Book Description
Unlike some other reproductions of classic texts (1) We have not used OCR(Optical Character Recognition), as this leads to bad quality books with introduced typos. (2) In books where there are images such as portraits, maps, sketches etc We have endeavoured to keep the quality of these images, so they represent accurately the original artefact. Although occasionally there may be certain imperfections with these old texts, we feel they deserve to be made available for future generations to enjoy.

Book Description
An in-depth look at the origin and evolutionary radiation of the synapsids. About 320 million years ago a group of reptiles known as the synapsids emerged and forever changed Earth’s ecological landscapes. This book discusses the origin and radiation of the synapsids from their sail-backed pelycosaur ancestor to their diverse descendants, the therapsids or mammal-like reptiles, that eventually gave rise to mammals. It further showcases the remarkable evolutionary history of the synapsids in the Karoo Basin of South Africa and the environments that existed at the time. By highlighting studies of synapsid bone microstructure, it offers a unique perspective of how such studies are utilized to reconstruct various aspects of biology, such as growth dynamics, biomechanical function, and the attainment of sexual and skeletal maturity. A series of chapters outline the radiation and phylogenetic relationships of major synapsid lineages and provide direct insight into how bone histological analyses have led to an appreciation of these enigmatic animals as once-living creatures. The penultimate chapter examines the early radiation of mammals from their nonmammalian cynodont ancestors, and the book concludes by engaging the intriguing question of when and where endothermy evolved among the therapsids. “Ever since Nick Hotton’s book from the 1980s we have needed an update on the biology of therapsids, and it has been Anusuya Chinsamy-Turan and her students and associates who through their bone histological work have made the greatest progress in this field.” —Martin Sander, Steinmann Institute, University of Bonn “Forerunners of Mammals is full of meticulous detail . . . [I]t also contains a number of excellently rendered illustrations of some of the animals covered in the book, and the final chapter is a discussion of the evolution of endothermy that anyone with a background in biology might find of interest. . . . Recommended.” —Choice “Forerunners of Mammals will take interested readers beyond the classic jaw-to-ear appreciation of therapsids, towards a deeper appreciation of the ancestry of mammals.” —Journal of Mammalian Evolution “This volume represents a state-of-the-art contribution to our understanding of the paleobiology of how mammals arose, and what factors contributed to their evolutionary radiation and eventual success. It is highly recommended for anyone interested in these topics, and will be accessible to readers with minimal background in bone histology and synapsid paleontology.” —Quarterly Review of Biology

Excerpt from Mammals Collected by the Swedish Zoological Expedition to British East Africa 1911 The costs of the expedition were chiefly defrayed by a friend of mine, who does not want his name mentioned in this connection, and by His Excellency Dr. Emanuel nobel. To these two gentlemen I wish to express my deepfelt gratitude for their generosity, but I keep also in grateful memory kind services rendered by other friends as well.

Book Description
As mammals ourselves, we have always been fascinated with this most advanced class of animals, and "Simon & Schuster's Guide to Mammals" describes 426 species worldwide. A long and thoughtful introduction to the evolution, characteristics, and orders of mammals is followed by the entries -- all illustrated in full color -- each containing the mammal's classification, description, and habitat as well as details on behavior, feeding habits, and reproduction. The entries also feature colorful symbols to illustrate habitat, color maps to show the distribution and rarity of each species, and line drawings to indicate unusual or notable physical features. With more than 500 color photographs, "Simon & Schuster's Guide to Mammals" is a superb and valuable reference.

Book Description
Excerpt from A Geographical History of Mammals Since the publication of Dr Wallace's book on the geographical distribution of animals in general, the only works which have appeared relating to Mammals from the same point of view are the small volume by Mr F. E. Beddard, and the series of papers by Mr W. L. Sclater, referred to in the Appendix. Both the latter admittedly take but little account of fossil forms and there is accordingly ample room for a work which? should collect and arrange the information on this subject, and it indicate the deductions which may be drawn therefrom. This task has been attempted in the present volume. The subject is, however, so vast, and the information relating to it scattered! through so many publications, that it is probable many points of interest or importance have not been noticed. From the mode. of arrangement of the work, a considerable amount of repetition was inevitable. The long time that the volume was in the press will account for its containing no allusion to certain papers which have appeared recently. It may therefore be mentioned here that recent discoveries have shown a slight intermixture of northern. types in the Palaeozoic flora of Argentina, so that the isolation of the northern and southern floras is not so nearly complete as was supposed.

Book Description
Excerpt from The Standard Natural History, Vol. 5: Mammals In the beginning of the third volume of tills series we have a general account of the anatomy and physiology of the branch of Vertebrata; and here, as an introduction to the class of Mammals, we need only to refer very briefly to some of the special diagnostic characters which separate this group from the other divisions of backboned animals. In this account we have intentionally omitted those features which are common to all ertebrates, and all description of physiological phenomena which, as explained in the ordinary school text-books of human physiology, will apply as well to the whole class of mammals as to man. The Mammalia, the highest class of the animal kingdom, is more distinctly marked off from all other groups than are many of the classes considered in the preceding volumes. While there frequently exists a doubt as to the proper boundaries of some of the lower groups, or their relative importance in the scale of perfection, no such hesitancy is felt regarding the limits or the grade of the mammalia. Even within the limits of the class the orders are all well defined, and in most cases their relative rank is pretty well settled. This superiority of the mammalia over all other classes of the animal kingdom does not imply that every organ is more perfect or better adapted to its purpose, or that every individual is really higher; but that when we come to regard the totality of the organization, and the setting apart of portions of the body for some specific purpose, resulting in an increased differention of organs and an increased complexity of the organism, upon which alone the relative rank of animal rests, the higher rank is at once evident. Thus the human eye, far from being the perfect organ described in some works of a teleological tendency, is less perfect than that of the eagle in many respects, and yet no one would think on this account of placing the bird of prey higher than man. Like all vertebrates, the mammals never have more than two pairs of limbs, but with the exception of some of the aquatic forms (whale, etc.), these two pairs are always present, whence the name in frequent use for the class - quadrupeds. The anterior pair of limbs are never absent in the group. Except in a few forms, to be noted below, the body is covered with hair. The mouth is usually armed with teeth. The heart is four-chambered, and the circulation is complete. The blood is warm and contains non-nucleated red corpuscles. The body cavity is divided into two portions by a transverse muscle, the diaphragm, or "midriff," the anterior portion being called the pleural, and the posterior, or abdominal portion, the peritoneal cavity. The young are born alive, and are afterward nourished by milk, secreted by milkglands (mammce), whence the name of the class.

Book Description
Excerpt from A Distributional List of the Mammals of California The system of entry adopted in the following list is simple. Of the higher groups only Orders and Families are given. The scientific name here adopted for the species is given in bold face, followed by the authority. A vernacular name has been selected - in many cases with difficulty, as is admitted. In nearly every case the original description has been verified from its original source. In the few instances where the cita tion is given within quotation marks, the citation is at second hand, that is, the original has not been seen by the writer. The type locality is usually just as given in connection with the original description; sometimes it is modified somewhat to make it more intelligible, for example, by giving the name of the county or of the nearest large town; and occasionally cor rections have been necessary. The synonyms are any other names - aside from those appearing in the heading and in the citation following orig inal description - that have been applied to the species as occurring within the state of California. Where a name now considered synonymous with the accepted one, was based upon a specimen from California, the full citation and type locality are given.
