tail separates it from this group and allies it, in proportions, 

 with the Felis eyra group, of which it appears to be a small, 

 dark form. 



1 8. Urocyon guatemalae Miller. Two specimens, an adult 

 female and a two-thirds grown male, from Pozo Azul, July 17. 



The adult female agrees very closely in size, cranial charac- 

 ters, and coloration with topotypes of Mr. Miller's U. guate- 

 malce, except that the whole dorsal area is much blacker, and 

 the ears, sides of the neck, outer edges of the limbs, and under 

 surface of the tail are darker, being ochraceous brown instead 

 of "tawny ochraceous." On the back the black tips of the 

 hairs are so long and abundant that the prevailing color of the 

 middle portion of the back is black. The audit al bullae are 

 also less inflated. Probably additional material would show 

 the desirability of recognizing the Costa Rican animal as sub- 

 specifically separable from U. guatemalce. 



19. Conepatus (Marputius) marpurito (Gmeliri). Two 

 specimens, an adult female from Pozo Azul, June 6, and a 

 young male from Rancho de R. Jimenez, April 21. Female, 

 total length, 610; tail vertebrae, 175; hind foot, 49. 



These specimens are very different from C. tropicalis, from 

 the eastern coast of Mexico, both in coloration and in the 

 form of the skull. In the absence of Colombian specimens of 

 true C. marpurito, they are provisionally referred to it on the 

 basis of Mr. Thomas's statement (Ann. and Mag. Nat. Hist. 

 (7), V, June, 1900, p. 500) that "true C. marpurito 

 occurs at Bogota and north-westwards into Central America."
