EINAR LÖNNBERG, MAMMALS FROM ECUADOR. 15 



especially on the lower flanks. The light rings of the hairs 

 are broader on the flanks than on the back, but often some- 

 what cream-coloured. The upper snrface of the tail is »warm 

 sepia» (Rép. de Coul. 305,i), some few of the hairs of the 

 basal portion with creamy rings. The lower side of the tail 

 is pure white. The hairs of the upper surface are about 8 

 cm., those of the lower side and at the end about 11 — 12 cm. 



The face is warm sepia, inclining to black, thickly sprink- 

 led with white rings from a little above the rhinarium and 

 upwards, but in the posterior portion of the interorbital 

 regions the rings cease, and then follows a broad parietal 

 area, which is uniformly a dark shade of warm sepia. This 

 area is prolonged in a short tip över the nape, but is not 

 continued into any line över the neck. The outside of the 

 ears is grizzled grey, paler at the base behind, the inside 

 with long white hairs. The sides of the head in front of the 

 eyes dark grey with white sprinklings, and the eyes them- 

 selves are surrounded by broad whitish rings. A broad band 

 of warm sepia, nearly black, behind the rhinarium from lip 

 to lip. In front of the same and between it and the rhina- 

 rium a white spöt on the upper lip, and behind the black 

 band on either side a whitish band to the corner of the 

 mouth, but these whitish band do not meet on top of the 

 nose. The chin is white, bordered on either side by a black 

 spöt on the lower lip, and in the middle by a smoky grey 

 white-sprinkled band from the sides of the head; behind this 

 the interramial space and the throat are white. The före 

 neck is smoky grey more or less overlaid with white; the 

 chest and breast resemble to some degree »avellaneous» 

 (RiDGVAY 1912), towards the axillary region with a some- 

 what buffy tint, and behind blending into the white of the 

 belly. Proximally the limbs are white on their inner side, 

 which distally is continued as a stripe down the posterior 

 side, otherwise the limbs are brownish grey as the body 

 colour, sprinkled with whitish, but without any dark mark- 

 ings, rather paler on the digits than on the metapodials. 

 The tuft of the tarsal gland is very dark brown, most re- 

 sembling »van Dyke brown» (Ridgway 1912), and its sur- 

 roundings are rusty yellow. 



Mesially on the back, about 22 cm. in front of the root 

 of the tail, there is a naked spöt measuring about 6 cm. in
