DECEMBER, 1903. MAMMALS ELLIOT. 247 



This desert rat is noticeable for its gray color, with hardly any 

 red showing, so often conspicuous in its relative N. f. macrotis. It 

 would seem to be the desert representative of that race. Mr. Heller 

 found it only at .the type locality where seven specimens were taken, 

 and the extent of its distribution has not been ascertained. 



Neotoma desertorum grandis. Subsp. nov. 



Type locality: Cameron Lake, Sierra Nevada, Kern County, Cali- 

 fornia. 



Genl. char.: Similar to N. desertorum, but larger; tail more hairy 

 and blacker above. 



Color: Upper parts mixed buff and black; sides and thighs brighter 

 buff with less black; nose and sides of face buff; under parts and feet 

 white; under fur along sides and thighs plumbeous; hairs on throat, 

 chest, and middle of ventral surface white to the roots; tail very hairy, 

 black above, white beneath; ears pale brown, tuft of buff hairs at base 

 succeeded by a band of black hairs near middle of ear. 



Measurements: Total length, 385; tail, 185; hind foot, 38; ear, 

 30. Skull: total length, 47; Hensel, 40; zygomatic width, 23; inter- 

 orbital constriction, 6; length of nasals, 17; palatal length, 21; length 

 of upper tooth row, 8; length of mandible, angle to tip of incisors, 

 30; length of lower tooth row, 9. 



This is a large rat, equaling in size N. f. streatori, but with the 

 coloring of N. desertorum, and a larger hind foot than that species; in 

 fact, the two specimens from Cameron Lake are exactly alike in 

 appearance with topotypes from Furnace Creek, Death Valley, except 

 the black tail, but the gfeat size at once separates them from the 

 longer known species. The skull, save in its greater dimensions, 

 offers no particular differences from that of N. desertorum. 



TEONOMA. 



Teonoma cinerea *acraia. Subsp. nov. 



Type locality: Hot Springs, Long Canon, Mount Whitney, Inyo 

 County, California. Altitude 8,000 feet. 



Genl. char.: Similar to T. cinerea, but much paler, tail paler, foot 

 smaller. 



Color: Upper parts pinkish buff lined with black on top of head and 

 dorsal region, lightest on rump; sides of face and flanks pinkish buff 

 with very little black showing; this color extending over shoulders 



* axpatoff dwelling on the hills.
