NO. 2028. PHILIPPINE LAND MAMMALS— H0LLI8TER. 319 



Mindanao: Davao, 3 (Mearns); Margo Satiibig, 2 (Kierulff); Pan- 

 tar, 4 (Mearns); Todaya, Mount Apo, 2, including the type (Mearns). 



I am unable to divide this species satisfactorily into island races 

 over all this range. In Mindanao and on some of the southern islands 

 forms are well marked. Doubtless a large series of specimens of 

 comparable age and pelage woidd make it possible to recognize races 

 on many of the northern islands as well. 



EPIMYS MINDORENSIS (Thomas). 



Specimens. — Eleven, from Mindoro: Mount Halcon (Mearns). 



On the evidence of specimens from the Alag River and lower slopes 

 of Mount Halcon, listed under Einmys mindanensis, I mistrust that 

 this handsome mountain species, distinct as it appears to be, does 

 really intergrade with the wide ranging lowland form. 



EPIMYS ZAMBOANGiE (Mearns). 



Specimen. — One, the type, from Mindanao: Zamboanga (Mearns). 



EPIMYS KELLERI (Mearns). 



Specimen. — One, the type, from Mindanao: Davao (Mearns). 



From the fact that no specimens referable to the true Epimys 

 neglectus of Borneo have been found in the material representing the 

 rattus group from the Philippine Islands in the United States National 

 Museum collections nor among the numerous specimens examined 

 for the PhiHppine Bureau of Science, I beheve that E. neglectus should 

 be dropped from the list of Philippine mammals. 



EPIMYS QUERCETI Hollister. 



Specimens. — Two hundred and fourteen, from locahties as follows: 

 Luzon: Haights-in-the-oaks, Benguet, 56, including the type (Mearns) ; 

 Manila, 158 (Mearns, Fox). 



The Manila examples are not typical and have shghtly smaller 

 teeth than the series from Benguet. The Manila specimens are, 

 however, mostly in alcohol, and without a series of skins it does not 

 seem best to attempt the separation of a form based on so slight an 

 average character. 



EPIMYS MAYONICUS, new species. 



Type. — 'From Mount Mayon, Albay Province, Luzon (4,000 feet). 

 Male adult, skin and skull (teeth considerably worn). United States 

 National Museum No. 144600. Collected June 5, 1907, by Dr. 

 Edgar A. Mearns. Original No. 6438. 



Diagnosis. — Externally hke Epimys querceti, but slightly less in 

 size, with more yellowish sides, hips, and underparts; pelage more 

 spiny than in any example of querceti in a series of over 50 specimens, 

 but these differ greatly among themselves in this respect. Skull 

 differs from that of querceti in its much narrower, almost parallel-
