than that at outer borders of interparietal, a condition the reverse 

 of that in Epimys norvegicus. Suture between premaxillary and max- 

 illary relatively further forward in front of antorbital foramen than 

 iu Epimys non'egicus. 



Teeth. The teeth in the only known specimen are slightly too 

 worn to show the exact details of the enamel folding. In general they 

 appeal' to represent a stage of reduction of the outer side of upper 

 molars corresponding to that of Epimys ml/us. Fourth tubercle in 

 both m} and m 2 with distincl outer reentrant angle. 



Measurements. Type: Head and body, 310 nun.; tail, 270; hind 

 foot (dry). 57 (53.6); skull, condylobasal length, 62.2; nasal. 28.0;

 greatest breadth across lateral ridges, 16.8; breadth across lateral 

 ridges posteriorly. 12. 8; interorbital constriction, 9.6; depth of brain- 

 ■ at middle, 15.8; least depth of rostrum behind incisors, 12.1; 

 maxillary toothrow (alveoli), 11.0; mandibular 

 toothrow (alveoli), ]().(). 



Specimen examined. The type. 



Remar -This rat conspicuously exceeds the largest hitherto 



•wn Philippine species in size. In this respecl it can only be com- 

 pared with Epimys imperator of the Solomon Islands; but it shares 

 none of the peculiar cranial character of the latter. 



EPIMYS GALA, new species. 



Type-specimen. Adult male (skin and skull). Cat. No. 144633, 

 U.S.N.M. Collected on theAlag River, Mindoro, November:!!). 1906, 

 by Dr. Edgar A. Mearns. Original number 6334. 



Diagnosis. A dark local form of the Epimys <r<nfti group; color 

 of underparts not conspicuously contrasted with that of sides; fret 

 blackish. Skull and teeth essentially as in Epimys everetti, but 

 audit al bullae smaller and molars larger. 



Color. Back and sides a coarse grizzle of black and dull, light 

 ochraccous-buir, the lighter color in excess everywhere except on 

 rump; shoulders with a slight grayish tinge; sides, cheeks, and outer 

 surface of legs somewhat lighter than back; underparts dull ochra- 



lus-buff, not conspicuously contrasted with >ide^. the line of 

 demarcation scarcely indicated: feet blackish brown, in noticeable 

 contrast with legs; tail blackish through somewhat less than basal 

 half, the distal portion yellowish. 



Skull and teeth. In all general features the skull agrees with that 

 of Epimys everetti, but the audit al bulla is noticeably smaller, its lon- 



udina] diameter decidedly less than distance between bases of 

 paroccipital p Teeth more robust than in the Luzon animal, 



the width of /;/' equal to fully three-quarters the least distance 



between tooth row
