327 



Measurements of adult skulls of Crateromys schadenbergi. 



APOMYS HYLOCCETES Meams. 



Specimens.— '^ine, including the type, from Mindanao: Mount 

 Apo (Mearns). 



APOMYS PETR.ffi;US Meams. 



Specimens. — Two, including the type, from IVIindanao: Mount 

 Apo (Meams). 



APOMYS INSIGNIS INSIGNIS Meams. 



Specimens. — Twelve, including the type, from Mindanao: Mount 

 Apo (Mearns). 



APOMYS INSIGNIS BARDUS Miller. 



Specimens. — Twenty-five, from localities as follows: Mindanao: 

 Catagan, 1 (Mearns); Mount Bliss, 12, including the type (Meams); 

 Mount Lebo, 3 (Mearns); Mount Malindang, 9 (Mearns). 



This form is a slightly characterized geographical race of Apomys 

 insignis. The only distinguishing character is the slightly narrower 

 skull, an average difference. 



APOMYS MICRODON, new species. 



Type. — From Biga, Catanduanes Island. Adult male, skin and 

 skull (teeth little worn), U. S. National Museum No. 155145. Col- 

 lected May 8, 1909, by D. B. Mackie. Orig. No. 6. 



Diagnosis. — Of medium size, slightly smaller than the Mindanao 

 forms; thus widely different from either of the two known northern 

 species, from Benguet Province, Luzon. Differs from all other 

 forms of Apomys in the relatively small size of teeth. 



Color of type (in worn pelage). — Upperparts dark cinnamon-brown; 

 sides lighter, almost tawny-olive; underparts buffy-gray, strongly 

 washed with pale cinnamon. Hands, feet, and tail brown, the tail 

 apparently unicolor. 



Slcull and teeth. — The skull of the single specimen is broken in the 

 posterior parts, but it is apparently much as in Apomys insignis 

 from Mindanao in general shape; the teeth are much less in size, 

 smaller than in any species of Apomys except the little Apomys 

 musculus of Luzon.
