It approaches more the triangular form, being distinctly of less anteroposterior 

 diameter on the outer side than the fifth tooth of the fragment from the White 

 Bluffs. It is also of slightly less transverse width than the fifth tooth of the 

 latter specimen. No. 23373 differs also from the fifth superior tooth of MegaJonyx 

 leidyi in smaller size and in shape. Compared to the corresponding tooth in 

 M. wheatleyi,-^ the California specimen is seen to agree in anteroposterior 

 diameter but differs slightly in transverse width (see measurements above). 

 According to Cope the shape of this tooth in M. wheatleyi is triangular but may 

 vary somewhat in different individuals. 



The second specimen, no. 23373 (fig. 296), is too fragmentary to allow definite 

 determination.

The specimen measures 51 mm. in mid-anteroposterior cross sec- 

 tion. It is believed to represent a large camel of the Pliaiiclienia type, 

 and with the fragmentary remains of the following section suggests 

 the probable prevalence of the camel in the fauna of this horizon.
