112 SHAWANGUNK HEAD. 



the great eight-pointed ultimate molar, with a distinct talon bearing two 

 very small mammillary eminences. 



This head differs, therefore, remarkably from the head of the skeleton, 

 in having two more teeth on the right side, making in the whole, ten teeth ; 

 while in ours and the Cambridge skeleton are only eight, and in the oldest 

 heads only four (as in the elejmant) ; whence we may conclude, that the 

 individual to which this head belonged was young at the period of its 

 death, and might, had it reached a great age, have attained an immense 

 size. As it corresponds in magnitude and in many of its measurements 

 with the great skeleton, we venture not to assume for it the claim of belong- 

 ing to another species.

parietalia anteriorly, and presents a rough space from two to three inches 

 in width, of a semi-lunar form ; constituting, with the ossa nasi, the superior 

 boundary of the nasal aperture. On the sides of the head, and in a lateral 

 direction, the ossa parietalia extend downwards about three-fourths of the 

 zygomatic fossa, where they unite with the temporal bone. 

 Temporal The temporal bone forms the posterior part of the zygomatic fossa;

thence extends backwards to form the inferior part of the occipital ridge. 

 At this point it bifurcates into the mastoid process on the back part, which 

 is of a flattened form, and more distinct than in the elephant ; and ante- 

 riorly into the zygomatic process, which, extending forwards, constitutes 

 one-third of the posterior portion of the zygomatic arch, being at this point 

 united with the posterior third of the jugal bone. The external auditory 

 foramen, situated at the root of these two processes, is of an oval form, and 

 about three inches in diameter ; its depth is, thirteen inches.
