1922] Kellogg: Pinnipeds from Miocene and Pleistocene Deposits 35 



A canine tooth from the Vaqueros formation near the Stage 

 Station, Section 4, Township 28 South, Range 38 East (Bakersfield 

 Quadrangle), was sent to the Department of Paleontology by O. A. 

 Cavins for determination. It is included here because it has many 

 points in common with Allodesmus, though it is not considered to be 

 of this species. This canine is much smaller than that of Allodesmus 

 kernensis and may possibly belong to some immediate ancestor. The 

 roots of the canine of Allodesmus are grooved, the enamel on the crown 

 is wanting, and the internal face is much worn. The roots of this 

 tooth from the Vaqueros are ungrooved, the enamel on the crown is 

 relatively thick, and the internal face is deeply worn (fig. 15a). Con- 

 ditions of deposition have caused the loss of part of the enamel layer 

 on the external face (fig. 15ft.).

The radius (tig. 9) is represented by the distal portion alone, a 

 large portion of the surface being worn away. An accurate descrip- 

 tion is therefore impossible. The shaft is narrower and was without 

 doubt shorter than that of Eumetopias. The interosseous border is 

 wider and more rounded than the posterior border. On comparison 

 it was observed that the inner surface does not differ in any marked
