Book Description
Excerpt from Catalogue of the Neotropical Squamata, Vol. 1: Snakes One Star: Low reliability. Keys and Synonymies prepared by us from existing literature; difficulties encountered by us because of insufficient descriptions, non - availability of critical specimens, or other reasons; manu script not checked by outside reviewer, since no one is currently engaged in revisionary study of the genus, to our knowledge. In the case of monotypic genera, one star means we have reasons to doubt its validity as a distinct genus. Two Stars: Moderate reliability. Keys and Synonymies prepared almost entirely by us, but usually checked against specimens and adequate information in the literature; manuscript often reviewed externally, although not necessarily by specialist actively studying genus. Further study needed to give better understanding of genus. Three stars. Good reliability. Keys and synonymies prepared either by us in consulta tion with a specialist or by the expert himself, or modified from monographs, check lists, or regional studies. Added work is usually in progress on the genus by the specialist, and we anticipate early publication by him to improve our understanding even more. Four Stars. High reliability. Manuscript either prepared externally, in which case the author is acknowledged in the heading material; or taken by us from a very recent generic mono graph summarizing the literature and including all available specimens for study.
