skull of this Geotrypetes^ I come to the conclusion that 

 the genus is valid, for the squamosals are not in contact 

 with the parietals, as in Hypogeophis rostratus. It may be 

 thus defined : — 



Geotrypetes. 



(Peters, Sitz. Ges. naturf. Fr. Berl. 1880, p. 55.) 



Squamosals separated from parietals. Teeth large, nume- 

 rous in inner row of mandible. Eyes visible. Tentacle 

 flap-shaped; tentacular groove horseshoe-shaped, situated 

 below and behind the nostril. Cycloid scales imbedded in 

 the skin. 



A single species, from West Africa : — 



Geotrypetes Petersii.
