in part from Osborn and 



III. TJie Brain. 



No specimen of the brain-cast is preserved in the Princeton 

 collection. Osborn and Wortman's figure shows that it was 

 decidedly more advanced than in the case of any other White 

 River genus so far known. Their account is as follows : 

 "The brain is deeply convoluted. We observe upon "each 

 hemisphere four longitudinal gyri ; these, according to Owen's 

 nomenclature, would be the median, medilateral, suprasylvian, 

 and sylvian" (No. 8, p. 355). A remarkably modern feature 

 of this brain is in the width of the cerebral hemispheres, as 

 compared with their length, and in this respect, as well as in 

 its richness of convoliition, it is superior to the brains of the 

 small modern deer, such as MoscJms, Hydropotes, Cervus 

 hiwiilis, etc.
