ciraen differs from, or cau add to Temminck's figure, which probably 

 has been of a younger individual. 



The sutura coronalis (the frontal - parietal suture) makes in our 

 speciraen a sharp angle, whilst, in Temminck's and in a young spe- 

 cialen which (by the kindness of Mr. Thomas) I had the opportunity 

 of examining in the British Museum last year, it forms an almost 

 straight line. 



A distinct crista sagittalis proceeds from about the middle of 

 the frontalia, and is posteriorly joined to two elevated cristae occi- 

 pitales. In Temminck's drawing and in the young specimen in the 

 British Museum, the upper portion of the skull is smooth. 



The pars mastoidea forms an inflated bulla, leaning immediately 

 against the bind margin of the auditory bulla, so that there appear 

 to be on each side two bullae, the posterior one about ^'^ less than the 

 anterior. 



The foramina palatina are not evenly elliptical, as in the dra- 

 wing of Temminck, but contracted behind, and the inner margin is 

 curved. 



The teeth. The dentition is normal: 



* I, c I, p I, m i (46). 



In the Upper jaw the central incisors are considerably longer and 

 thicker than the others, and touch each other at the points. The 

 other incisors become successively sraaller; i '^ is thus not inconsi- 

 derably thicker than the two outermost pairs.
