Specimen. — One, the type, from: Cagayan: Cagayancillo (P. B. S.). 



EPIMYS DATiE (Meyer).

 (Mearns).

EPIMYS BENGUETENSIS, new species. 



Type. — From Camp John Hay, Baguio, Benguet Province, Luzon 

 (5,000 ft.). Adult female, skin and skull (teeth moderately worn), 

 U. S. National Museum No. 145790. Collected May 1, 1907, by 

 Dr. Edgar A. Mearns. Orig. No. 6405, 



Diagnosis. — Like Epimys datse but smaller and lighter colored; the 

 underparts conspicuously different, light buff with a strong tendency 

 toward ochraceous [in datx naphthaline yellow]. 



Color of type (in worn pelage) . — Upperparts mixed gray and ochra- 

 ceous-buff, the hairs broadly dark gray at bases, tipped with 

 ochraceous-buff. Cheeks and sides much lighter, almost pure warm- 

 buff, the under fur of a lighter shade than on back. Entire under- 

 parts light buff, with a strong wash of ochraceous, the hairs very light 

 gray at bases. Feet pinkish-buff with a faintly darker streak along 

 upper surface; tail light brown, unicolor; whiskers dark brown and 

 black [in datse mixed with white]. 



Slcull and teeth. — -Except for its smaller size the skull does not differ 

 appreciably from that of Epim^ys datse,. The last upper molars lack 

 the antero-internal supplementary cusps, but that this is a somewhat 

 variable character in datx is shown by one specimen in which this 

 cusp is present on one side and absent on the other. 



Measurements of type (estimated from dry skin) . — -Head and body, 

 130 mm.; tail, 130; hind foot, without claws (moistened), 32. Skull: 

 Condylobasal length, 33.3; zygomatic breadth, 16; interorbital
