Bassaricyon sp.? In this collection is also a skin of a 

 Bassaricyon collected on the eastern side of the Andes, viz. 

 at Baeza, on the road to Napo, alt. about 6000 f., V-s 1920. 

 Unfortunately there is no skull to this specimen and an 

 exact determination is thus impossible (perhaps it might be 

 B. alleni). It appears to be somewhat larger than the speci- 

 mens of B. g. medius, and with regard to the coloiir it is 

 duller, because the rings of the hairs are not buff, but dirty 

 whitish, and the tips rather blackish. By this a more grey- 

 ish brown general tone is effected, especially on the flanks. 

 The under parts are påle buffish in the middle, otherwise 

 more greyish white with a slight buffish tint. The hands 

 and feet are påle greyish brown, somewhat grizzled.
