Remarks.— Dr. Merriam has kindly lent me an adult topotype 
of his P. erinitus for comparison with my series. P. crimitus 
scitulus is much paler, its tail is shorter, less hairy, and grayish 
above,— the tail of true P. crinitus is black above. FP. cranttus 
scitudus needs comparison with no other form. In color it is very 
like P. ¢ruez from the same region, but it always can be told from 
that animal by its smaller size, smaller ears and different tail — 
longer, less hairy, and less sharply bicolor. The adult examples 
of . ¢ruet also have more fulvous or pinkish on the lower sides 
and rump. In the collection made by Messrs. Price and Simons 
there are many examples of P. crinztus scitulus and P. truet taken 
on the same dates, so that the two species probably occur 
together. 
Arctomys flaviventer avarus' subsp. nov. 
Type, from Okanagan, British Columbia, 2, young, no. 7299, coll. of E. A. 
and O. Bangs, collected July 17, 1897, by Allan C. Brooks. 
Subspecific characters.— Similar in markings and general characters to true 
A. flaviventer ; colors all much paler; on the back and shoulders the black 
central bands of the hairs are much shorter and the yellowish and grayish tips 
much longer, giving to these parts a lighter and more hoary appearance; yel- 
low of under parts, feet, and hands, paler. Skull similar to that of true 4. 
flaviventer except that the nasals end on a line with the ends of the maxillary 
arms. In true 4. fleviventer the nasals extend a considerable distance behind 
the ends of the ascending branches of the maxilla. 
Measurements.—Type, 2 , youngish: total length, 457; tail vertebra, 140; 
hind foot, 70 mm. 
1A varus — greedy.
