against the species — “Skull unknown.” That this remark may 
be no longer applicable, is the object of the present paper. 
Although I have only one skull at my disposal, and that damaged, 
the mutilation is not of such a character as to interfere with 
features necessary for comparative purposes.

Description ,— Skull stout and heavy, sides of muzzle slightly 
convex. Nasals somewhat expanded behind, their lateral edges 
concave, narrowest in the middle, posterior suture forming an 
obtuse backwardly directed angle. Ascending pi’ocesses of pre- 
maxillm greatly and suddenly broadened above, otherwise the pre- 
maxillo-maxillary suture not greatly inclined. Naso-premaxillary 
somewhat less than the naso maxillary suture. Frontal region 
narrow, immensely swollen, the supraorbital edges sharp and well 
defined ; they are coincident with the fronto-parietal sutures, 
coalescing where joined by the median frontal suture, thence 
forming a single prominent sagittal crest to the interparietal. 
Intertemporal area narrow, little more than the narrowest breadth 
of the nasals combined, and equal to their anterior breadth. 
Posterior palate without vacuities. In consequence of the inter- 
parietal and occipital bones having been removed, their condition, 
and also that of the foramen magnum cannot be described. 
Teeth . — The peculiarities already recorded are generally borne 
out by this example. I 1 descends much below l 2 and I ,} ; the 
two latter are equal in length, I 3 being much the broader. The 
canine is about three-quarters the length of the smaller incisors 
and proportionately strong. The premolar has no external ledge 
and the posterior ridge is deeply notched. The molars are perhaps
