4. Dermophis sechellensis, sp. n. (Fig. 3.) 



14 or 15 teeth on each side of upper jaw, 12 on each side (outer row) of lower jaw. 

 Snout obtusely pointed, prominent; eyes rather indistinct or scarcely distinct, the distance 

 between them nearly equal to the length of the snout ; tentacle in front of and below the 

 eye, three times as distant from the nostril as from the eye. Body short, its diameter 

 17 to 22 times in the total length; 147 to 160 folds, the first 18 to 26 complete, the 

 following alternately complete and interrupted, the last 43 to 77 complete. Tail indistinct, 

 rounded. Dark brown or blackish ; vent usually in a whitish spot. 



Total length 190 mm. 



Overlooking the very small inner mandibular teeth, I referred the first specimens 

 obtained by Prof. Gardiner to the allied Cryptopsophis multiplicatus, and recorded them 

 under that name in my previous list. The larger material which has now been placed at 

 my disposal shows this Csecilian to belong to the genus Dermophis, of which four species 

 occur in Tropical America, one in the West-African Island San Thome - , and one in British 

 East Africa.
