While resembling O. jalapce in the color of .the upper parts, 

 this Rice Rat differs so much in the hue of the under parts, the 

 proportions of body and tail, and in the shape and dimensions 

 of skull, that it seems more entitled to a distinct, independent 

 rank than a subspecific one. The skulls of the present form 

 and O. jalapte are quite different and recognizable at a glance; 

 the long, narrow braincase, restricted spread of the zygomatic 

 arches, long anterior palatine foramina, and lighter mandible of 

 the present form distinguishing it at once from its relative, not 

 to mention the shorter tail and longer hind foot and pale under 

 surface. By the kindness of my friend Dr. J. A. Allen I have 

 been able to compare my specimens with topotypes of O. jalapce. 

 Seven specimens of the new form were obtained at San Carlos, 

 Vera Cruz, by Mr. N. G. Buxton. 



NEOTOMA. 

 Neotoma fuscipes *cnemophila, Subsp. nov. 



Type locality. Lock wood Valley, Mount Pinos, Ventura 

 County, California. 



Genl. Char. Size large; tail long, black above; general hue of 

 upper parts buff. 



Color. Upper parts and sides buff with the base of hairs dark 

 plumbeous, and this latter coloring manifests itself on the 

 dorsal region and head, causing these parts to be darker than 

 * z*r t ri.<',z heights, and ^./.toi to love.
