68 Merriam Five New Mammals from Mexico. 



upper and outer sides of forelegs and feet except a small irregular yel 

 lowish blotch on top of forefoot. [In tropicalis the color is paler, the 

 yellowish of underparts reaches down on inner side of hind leg and foot 

 to toes, which are mainly yellow, and the forefeet and wrists are yellow 

 all round.] Underparts with orange fulvous deeper and concentrated 

 on belly and thighs, leaving throat and sides of neck white in contrast; 

 facial white markings complete, the side stripe reaching above plane of 

 eye, the patch between eyes large and broad (not restricted as in tropi 

 calis); black cheek patches much larger and broader; no black spot 

 under ear. 



Cranial characters. Skull like that of tropicalis but bullae decidedly 

 smaller and with anterior ends more obliquely cut off; zygomata shorter, 

 heavier, and more highly arched. 



Nasua narica molaris subsp. nov. 



Type from Manzanillo, Colima, Mexico. No. fffff $ ad., U. S. Na 

 tional Museum, Biological Survey Collection. Collected Feb. 7, 1892 by 

 E. W. Nelson and E. A. Goldman. Original No. 1844. 



Characters. Similar to N. narica from eastern Mexico but gray of 

 face more restricted; tail longer; skull slightly larger; molariform teeth, 

 particularly the upper ones, very much larger and more massive. 



Measurements. Type specimen ( $ ): total length 1240; tail vertebras 

 680; hind foot 122. 



Remarks. Externally this subspecies appears to present most of the 

 color variations of narica from the east coast, but in the type and another 

 specimen from Manzanillo the face is very much darker, the gray ring 

 around the nose being narrower and more mixed with dark hairs and 

 the gray bands connecting it with the superciliary stripe being nearly 

 obsolete; the ground color in the type specimen and a female from the 

 same place collected the same day is dark brown, lightened on the neck, 

 shoulders and anterior part of back by a profuse grizzling of buffy or 

 ochraceous hairs.

 S. National Museum, Biological Survey Collection. Collected Sept. 4 

 1896 by E. A. Goldman. Original No. 10,142. 



Characters. Size small for a Platygeomys (about equaling P. fumosus 

 from Colima); general appearance and characters as in P. planiceps but 

 color paler and duller (less chestnut); size smaller; rostrum and nasals 

 shorter; frontal flat interorbitally (not elevated on each side over the 

 orbits); zygomatic arches parallel (instead of strongly divergent ante 

 riorly); jugal light and slender, its faces not strongly developed.
