LOWER PLIOCENE SNAKE CREEK BEDS. 



79 



ramus of the lower jaw, an ulna and some other bones, of which 

 the lower jaw (No. 12078 Princeton University Geological Museum, 

 collecting locahty lOOoC) is here figured to give some idea of its 

 size and proportions. The fragment retains alveoli for the canine, 

 four double-rooted premolars and the sectorial molar. The first 

 and second premolars are separated from each other by a short 

 space, and from the canine and first molar by long diastemata, whlie 

 the rest of the dentition is in close series. 



Fig. 2. fAmphicyon sp. indesc, No. 12078, right ramus of the lower jaw, 

 side and top views, one half natural size. 



Brachypsalis obliquidens sp. nov. 



Type No. 12070 Princeton University Geological Museum, col- 

 lecting locality loooC, the left ramus of the lower jaw with P2-m2" 

 and alveoli of the canine and first premolar (Fig. 3). This is a 

 decidedly larger, deeper- jawed, heavier-toothed species than 

 Brachypsalis pachycephalus, with the anterior premolars placed 

 very obliquely to the tooth-row and all the teeth closely crowded. 

 It is of about the same size as Paroligobunis (Brachypsalis) sim- 

 plicidens from the Lower Harrison, but has a larger second molar, 

 a slightly larger sectorial and more closely crowded, obliquely placed 

 anterior premolars.
