The acrodont amphisbaenids have been studied, and detailed descriptions are presented of the integument, skull and mandible, cervical vertebrae, hyoid, and shoulder girdles of four of the six species. Brief comments are made on the degree of lung reduction and nature of dermal innervation. 2. Forms recognized are (forms of which no specimens were available are marked with an asterisk, *): Trogonophis wiegmanni Kaup; Pachycalamus brevis Günther; Diplometopon zarudnyi Nikolski; Agamodon anguliceps Peters; *Agamodon compressus Mocquard; *Agamodon arabicus Anderson. 3. The subspecies A. anguliceps immaculatus Calabresi, placed in A. compressus by Loveridge (1941), is returned to its original species. 4. Reasons are presented for considering the acrodont forms as a distinct subfamily, the Trogonophinae, clearly separated from other amphisbaenids by a number of structural characters and a special mode of digging. 5. The problems encountered by burrowing species are analyzed on a theoretical basis. The theoretical analysis is tested on the basis of observations on the Florida amphisbaenid species Rhineura floridana Baird. The possible burrowing mode of the Trogonophinae is analyzed on the basis of differences from the pattern exhibited by rhineurine species"--P. 201.17441137 bytesapplication/pdfen-USQH1 .A4 vol.119, art.3, 1960TrogonophidaeAmphisbaenidae -- Adapatation.Amphisbaenidae -- Africa, NorthAmphisbaenidae -- Middle EastReptiles -- Africa, NorthReptiles -- Middle Easttext
