DESCR. In its general aspect, the species here referred to is thick 

 and short. The body is depressed, wider than deep, and, as usual, 

 thicker upon its middle region. A contracted neck separates the body 

 from the head. The latter is plane upon the occipital region, convex 

 above the eyes, hence, very declivous forwards. The snout, conse- 

 quently, is wedge-shaped, with both jaws equal. The cleft of the 

 mouth is subconcave in advance of the eye ; its angle is nearly hori- 

 zontal, with a tendency of being depressed. The limbs are slender :
