162 Bangs New Mammals from Santa Marta, Colombia. 



feet and hands pale brown, in dried skin ; ears hairy at base outside, 

 naked inside and for rather more than half their length outside ; a gray 

 mark across base of ear, rest of hairs brown ; tail naked above for about 

 half its length, below for about three- fourths its length ; hairy portion of 

 tail brown, like back, but the hairs unicolor throughout their entire 

 length ; naked portion, in dried skin, yellow, with some irregular black 

 spots, all near where the hair ends ; " testicles glaucous blue." * 



Measurements. 



Skull, type, 9 adult: basal length, 49; zygomatic width, 30.8; mastoid 

 width, 20.2; interorbital width, 9.8; width across postorbital processes, 

 15 ; length of nasals, 21.6 ; greatest length of single half of mandible, 39.2. 



Remarks. This handsome Philander is represe nted by four examples, 

 three taken at Pueblo Viejo at an elevation of 8000 ft. and one taken on 

 top of a small mountain near Santa Marta at 4000 ft. The Santa Marta 

 skin has a much longer tail and larger hind foot than any of the others, 

 but otherwise they are all four very similar. P. cicur is apparently 

 nearest to P. derbianus, but differs from that species in having rich brown 

 instead of white upper sides to arms and in lacking the gray dorsal stripe. 

 Another species that may be somewhat closely related is the P. oniatus 

 Tschudi of Peru, but this also has the gray dorsal stripe, which is wholly 

 absent in P. cicur.
