to Dr. O. P. Hay for examination. Dr. Hay has very kindly 

 furnished the following statement regarding these specimens. "I 



examined the pieces of turtles 

 sent me and compared them 

 especially with Clemmys mar- 

 morata from California. I 

 see no reason why they may 

 not belong to that genus, but 

 they certainly are not C. mar- 

 morata. The material is so 

 scanty that it seems to me 

 better not to describe it, or 

 at least not to name it. ' ' 



Occurrence : Virgin Valley 

 Beds; locality 1090, Virgin Valley, Humboldt County, Nevada.

At two localities several miles apart in the Thousand Creek 

 region, fragmentary specimens representing the ulna of a large 

 species of goose (fig. 3) were found. These specimens were ex- 

 amined by Mr. L. H. Miller who has kindly furnished the follow- 

 ing note regarding them. 



"No. 12556 is the distal portion of the left 

 ulna of a large anserine bird corresponding 

 most closely in size with the Recent Branta 

 canadensis. The fossil specimen slightly ex- 

 ceeds in size the only specimen of the Recent 

 form available for comparison, but the difference 

 is scarcely greater than exists within the range 

 of the species as it is known today. There is no 

 character that would exclude the specimen from
