interesting from its apparent bearing upon the question of the 

 morphology of the cranium. If my interpretation of the general con- 

 dition, and identification of parts, be not incorrect, there are un- 

 equivocal indications that this skull is composed of four vertebrae. 



The modifications of the cranial bones produce a singular configura- 

 tion of the external parts. The snout, or nose proper, is separated from 

 the mouth-parts by a wide and deep fissure, reaching half way to the 

 ears, in a horizontal plane, and in the longitudinal axis of the head. 

 At the base of this fissure there is a transverse slit in the skin, 

 across from side to side, representing the eyes, meeting on the 

 median line, and directly continuous with each other; this cutaneous 

 opening is about an inch and a third long by a third wide in the 

 middle. With the exception of this slit, the whole face is contin- 

 uously covered with proper integument, of normal texture, sparsely 

 beset with slender white hairs. The gape of the mouth is unusually 

 small; the lower jaw and lips offer nothing very peculiar; but the 

 upper jaw is much shortened (through intermaxillary deficiency, as 

 will presently appear) and the lip is extended some distance beyond 

 it, to meet the lower lip; it is compressed from side to side, and has no 

 nasal opening. The lower jaw bears six teeth, whereof the two lat- 

 eral ones on each side are conical, acute and enamelled; the median
