occiput. According to the published figures of IJ . hakelensis, 

 the vertebral centra are higher than long. This is confirmed 

 by the examination of three small specimens in this collection. 

 In .4. hathshebcB, on the contrary, the centra are longer than 

 high, longer, in fact, than the height of the centrum and the 

 neural arch taken together. The figures of U. hakelensis 

 show that the portion of the body in front of the anal fin 

 measures 38 mm., the portion behind this fin to the base of 

 the caudal, 53 mm. In A. hathshehce the two portions of the 

 body are practically equal. Of course, the presence of ven- 

 tral fins in A. bathshebce and their absence in U. hakelensis 

 constitutes the most important difference between the two 

 species; but the other differential characters given ma}* en- 

 able us to distinguish specimens when the region of the ven- 

 tral fins is injured or absent. 



Named in honor of Bathsheba, who attained the distinc- 

 tion of being a wife of one great king and poet and the mother 

 of another great king and poet.

The types of this species are No. 4514a (3765) and No. 

 45146 (3766). These specimens are both from Hakel. 



No. 4514a (3765) (PI. XXXVII, Fig. 2) presents a vertebral
