Book Description
Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1955, Vol. 113 Today it occupies a purely Holarctic range. Northward it reaches northern Scandinavia, the Baikal region of Siberia, Kamchatka, southeastern Alaska, and southern Labrador. South ward it reaches Madeira, North Africa, northern Iraq, the south ern Himalayas, the mountains of Formosa, the mountains of central Mexico, and northern Florida. Where it comes closest geographically to tropical faunas, as in southeastern Asia, it still retains its north-temperate character, i.e., limited to tem perate vegetation at higher elevations and there associated chie y with typically Holarctic ant genera.

Book Description
Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1954-1955, Vol. 112 The other genus fairly well developed in Africa is Strumi genys, which survives as fourteen known, valid species in the Ethiopian Region, plus one in Madagascar. Two of the Ethiopian species have become established as tramps outside Africa Madagascar (rogem' and scotti), and these will be discussed be low. All of the African Strumigenys species clearly belong to one ancestral stock, of which the most generalized known species is S. Grandidieri of. Madagascar, although the close interrelation ship of these species is masked by extensive morphological radia tion and might not therefore be guessed at without one 's having the complete series of forms in intergrading array. Undoubtedly, other species from these regions remain undescribed and ancol lected, but in spite of the incompleteness of the record, it seems clear that the afro-madagascan Strumigenys fauna is a very limited one compared to the two other distinct faunas of the genus. The New World and indo-australian faunas share, roughly equally, at least 100 described and undescribed species that I have been able to verify to date, leaving out those that are clearly synonyms.

Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1960-1961, Vol. 123 Since the illustrated bones of A. Iong-irmana are most surely not from one individual, it is important to point out that there may be as much as a 13-per cent variation in size between the largest and the smallest specimens of the same element. 011 making comparisons of bones that articulate with each other, as, for example, the radius and ulna (figs. 7 and this size dif ference becomes at once apparent. The terms more feline or more canine used in the fol lowing pages do not imply that these similarities indicate close taxonomic relationships between these forms and Amphicyon.

Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1961, Vol. 125 The straight-hinge larva of the sea scallop is similar to that of other lamellibranchs. It has a wide hinge-line, is relatively long in proportion to its height, and is almost equally rounded at both ends (pi. The two valves are hinged dorsally, the mar gins meeting ventrally and laterally. The minuteness of the shell, its transparency, and lack of structure leave few characters of importance to aid in identification at this early stage. Both valves are similar in size, shape, and curvature. They are fairly flat, and lack color. The hinge-line is usually straight, but in occasional specimens, it curves inward slightly. The size ranges from 60 to 80 microns in height and 80 to 115 microns in length in 7 -day-old laboratory-reared specimens.

Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1957, Vol. 116 Because of its geographical nature, the mainland of China has been separated into thirty provinces. Scorpion flies and hanging flies occur in all those (about half) to which expeditions have been made. Since previous expeditions did not include most Of'the mountainous areas of any of the provinces and no expedi tions at all have been made for Mecoptera in fifteen of the pro vinces, I believe our collections and knowledge of this order in China are still very incomplete.

Excerpt from Bulletin of the Museum of Comparative Zoology at Harvard College, in Cambridge, 1957, Vol. 117 Also, we should remind the reader, who may not be familiar with the use of the trawl in deep water, that the depths of cap ture reported by this method, under the several genera, are in reality those at which the trawl was dragging on the bottom. This is not necessarily the depth at which the shark in question was living, for it is always possible that any particular specimen (even of the species that hold closest to the bottom) may have been picked up when the trawl was being lowered, or hauled up again through the water. The only precise data in this regard are for specimens caught on hook and line. And we have very few definite records of depths of capture for line-caught sharks.
