The collection from the locality near Hanford (loc. 3031) in- 

 cludes the following forms : 



Megalonyx, small species, probably new. 



Equus or Pliohippus, ealeaneum 



Oamelid, small, near Pliauehenia 



Camelid, possibly larger than first mentioned form 



Cervid, antler fragments 



Leporid, new genus 



Fish vertebrae and other elements of skeleton 

 Testudo, fragments 



With the exception of the ground-sloth remains the material from 

 locality near Hanford (loc. 3031) is not well preserved, and this 

 form furnishes the only type diagnostic of any recognized faunal 

 stage. 



The Megalonyx specimen consists of a well-preserved maxillary 

 with all four cheek-teeth in perfect condition. The species resembles 

 the Pleistocene M. whcatlyi in size, but is probably new. 



A single specimen representing the horse group consists of a 

 considerably worn ealeaneum or heel bone somewhat smaller than the 

 average of ealcanea of the Pleistocene horses, and exceeding little if 

 any the average of Pliohippus from the West Coast Pliocene. It is 

 considerably larger than the specimens commonly found in the West 

 Coast Miocene. 



Of the camel remains none of the fragments can be generically 

 determined with certainty. A portion of a tooth and an incomplete 

 proximal toe bone seem to represent a type not more advanced than 

 those of the later Tertiary. They appear smaller and less specialized 

 than the known forms of the West Coast Pleistocene. 



Deer are represented by fragments of antlers, some of which show 

 the burr well preserved. The deer of the Pleistocene and later Ter- 

 tiary are not as yet well enough known to furnish a good basis for 

 comparison of the fragments represented in the White Bluffs col- 

 lection. 



A single upper cheek-tooth of a rabbit-like form obtained in the 

 White Bluffs beds is considered by Dr. Lee R. Dice to resemble in 

 its tooth-pattern a new genus known from the middle Miocene and 

 early Pliocene of northern Nevada. In this specimen the enamel 

 folds on the re-entrant angle are comparatively coarse, in contrast to 

 the finer folds seen in the teeth of the later rabbits. 



The fish and tortoise remains have not shown characters furnishing 

 definite evidence concerning geologic position.
