EINAR LÖNNBERG, MAMMALS FROM ECUADOR. 19 



lateral borders of this area bave the same colour to tbeir 

 roots, the longest bairs on tbe oceiput are more greyisb brown 

 at tbeir roots. Tbe long bairs on tbe dorsal side of tbe neck 

 are about 15 era. long gradually decreasing to about 12 — 11 

 cm. above tbe sboulders. Tbey are dull rust red at tbeir 

 extreme basal parts, tben follows along more or less a third 

 of tbe bair a buffy wbitisb zone, and after tbat a broad 

 zone of »warm sepia» (Rép. de coul. 305, i), and finally tbe 

 2—3 cm. long light tip, wbich is dirty wbitisb. On tbe middle 

 of tbe back tbe bairs are only 8 — 9 cm., tbe rusty coloured 

 basal zone is broader and brigbter, but tbe sepia-coloured 

 zone is missing, or only represented by a dull brownisb sbade, 

 wbicb is a little more pronounced on tbe sacral region, wbere 

 tbe bairs also increase in lengtb. On tbe flanks tbe bairs 

 bave a lengbt of about 11 cm. Tbeir extreme bases are not 

 so brigbt, but ratber similar to a påle sbade of fawn (Rép. 

 de Coul. 308, i), and tbe dark zone is »burnt umber>> (1. c. 

 304) of various sbades, sometimes also similar to Ridgway's 

 »verona brown»; towards tbe sboulders it darkens to »warm 

 sepia» as on tbe neck, and a t tbe same time tbe extreme 

 basal parts also become rusty. On tbe bind legs tbe dark 

 portion of tbe bairs is also »warm sepia», but tbe basal ligbt 

 portion diminisbes very mucb, wbile on tbe otber band tbe 

 ligbt tips get longer, often 5 cm. Tbe inside of tbe bind 

 legs, and tbe inside and front side of tbe före legs are almost 

 black, also on tbe outer side of tbe latter tbe ligbt tips 

 are not long except on tbe posterior fringe, so tbat tbere as 

 well as on tbe toes tbe warm sepia is dominating. Tbe bairs 

 of the fringe are 11 cm. on tbe upper arm gradually decreas- 

 ing to 9 cm. at tbe carpus. Tbe cheeks and tbe tbroat 

 are dark brown, ratber similar to Ridgway's »verona brown», 

 sharply defined from the påle colour of tbe upper parts of 

 tbe head. On the lower tbroat, före neck and chest tbe 

 bairs gradually become warm sepia with buffish white tips. 

 Ön tbe belly the lengtb of the bairs is about 2 cm., and tbe 

 ligbt tips are long enough to cover tbe there »burnt umber» 

 brown basal parts. The claws are bluisb grey horn colour 

 with black tips. Wben the living animal is hanging down 

 from the lower side of a branch the dorsal parts exposed to 

 view may look dirty buffish, tbe sides a ratber palc sbade
