Series A. into three subfamilies:— 1. AcrocJiordince.—The postfrontal bone produced over the supra- orbital region. Scales not or but sliglitly imbricate. 2. Coluhrince.—Postfrontal bone not produced over the supra- orbital region. Scales usually imbricate. Teeth on theentire length of the maxillary aud dentary bones. 3. RliachiodontiiKe.—Teeth rudimentary; maxillary and dentary bones edentulous anteriorly. Beyond these three subfamilies I am unable to divide the Agly-phous Coluhridce into groups (higher than genera) that may beregarded as natural and capable of definition. I have, however,arranged the genera of Coluhrince in two series according to thepresence or absence of hypapophyses or hnemal processes on theposterior dorsal vertebrae. This point (see fig. 12) is easilyascertained by making an incision along the belly in the posteriorfifth of the body, pushing aside the viscera, and disarticulating the COLUBKIDJ;. 171 rhaclii
