Color. Body, pectorals, and ventrals, light brown above, whitish beneath'; tail, 



dark brown throughout. 



Desdipttoii. Body ovoid, its lateral margins blending imperceptibly with the pect

the greatest depth. 



Eyes oval, of moderate size, situated obliquely, the greatest divergence posteriorly ; 

 distance between them being about three quarters that to tip of snout. The temporal 

 orifices are large, just behind the eyes, the anterior edge coming to a line with their middle 

 point; situated obliquely, in opposite direction to that of the eyes. Nostrils small, their 

 alae, large and projecting. Mouth moderate, transverse, curved anteriorly; teeth ses-

smooth longitudinal groove when at rest. Their number undoubtedly varies. Dekay 

 speaks of three being present, — and in the specimen from which his description is drawn, 

 but one is present, although the stump of a second, the anterior one and its distinctive 

 groove, afford evidence of its former existence. 



Anus longitudinal, near the origin of the tail. 



The greatest depth of pectorals on a line with the temporal orifices. 



The ventrals are fan-shaped, emarginated posteriorly. The claspers are rather more 

 than one half the length of the ventrals.
