Elliot from the collection of the Field Columbian Museum, convinces 

 me that they all belong to the present species. 



Neotoma fuscipes Baird. Round-tailed Wood Rat. 



Two adults and two young, June 13-15. These seem identical with 

 Berkeley specimens, and it is noticeable that one from each locality has 

 a partly bicolor tail. In this and other respects this rat seems subject 

 to much individual variation, and I cannot but think that some of the 

 recently established forms which do not seem to have any distinctive 

 geographic range will prove to have been based upon unstable charac- 

 ters. 



Microtus californicus (Peale). California Vole. 



One specimen, identical with those from Berkeley. 



Phenacomys longicaudus True. 



One female example of this rare mouse was found dead in a road, 

 June 30. 1899 (No. 11,625, Coll. Acad. Nat. Sci. Phila.). The occur- 

 rence of this species so far south of its previously known habitat in 

 C)regon is of particular interest, apart from the fact that this is, so far 

 as I am aware, only the third specimen that has been secured.^ 



In color this specimen is pale rusty, with an admixture of grayish- 

 white hairs, especially about the head and shoulders, and with long 

 rather inconspicuous black hairs scattered over the whole upper surface, 

 beneath grayish-white with the plumbeous bases of the hairs showing 

 through, feet pale rusty above, grayish-white below, tail dark brown 

 with a mixture of silvery white hairs below which make it appear 

 indistinctly bicolor. 



Length 170 mm., tail 70, hind foot 19. 



The skull resembles that of P. preblei (the only one available for com- 

 parison) in general appearance, but is relatively narrower. Basilar 

 length 20 mm., zygomatic breadth 14, occipito-nasal length 24, length 

 of nasals 7. The teeth have been described in detail by Mr. Miller. 

 Those of the present specimen are considerably worn. 



Thomomys bottae (Eydoux and Gervais). California Gopher. 



Three specimens. 



Lepus badnnani W^aterhouse. Bachman's Rabbit. 



Two specimens, a female and young male, July 6 and June 14. 



*Lepiis californicus Gray. California Jack Rabbit. 



Jack rabbits are reported as abundant in Mr. Bunnell's notes.
