quitensis, in which f. i. at least the greater part of the last 

 molar falls bebiiid the vertical through the anterior börder 

 of the orbit. 



Nasua nasiia subsp.? 



1 J" jun., Vio 1917, near Archidona, Napo, 3,400 feet 

 altitude. 



It is of interest to note that further down on the eastern 

 slopes of the Andes another species of Nasua lives below 

 N. guichua jivaro. It is very distinct from the latter with 

 regard to its much broader palate, much larger teeth etc., 

 as well as its different colour. As it is just shedding its 

 hairs, and so young that the permanent dentition is not 

 yet fully developed it can not be classified with full certainty. 

 It may only be mentioned that the före quarters show some 

 rufous hairs, but that the posterior back bas a black 2 V2 

 cm broad dorsal band, as the long hairs on the sides of this 

 are missing (only the dark sooty grey under fur remains), it 

 cannot be decided how widely the black colour is distributed. 

 The tail is strongly annulated by means of subequal black 

 and dirty whitish rings. 



Nasua olivacea quitensis Lönnberg. 



1 J^, lo/i 1915, below Nono, 8,500 feet altitude. 

 A quite typical specimen with the characteristic white 

 under fur. 



Mesosciurus hoffmanni Peters. 



1 ?, 10/5 1913^ Nanegal; 1 J^, ^i/j^ 1915, Piganta, western 

 slope of Mojanda, 8,800 feet altitude; I $, ^Vö 1912, road to 

 Mindo; 1 J" '^7» 1917, near Mindo, western slope of Pichincha, 

 7,000 feet altitude. 



Of these specimens the one from Pigan ta is by far the 

 brightest coloured with the middle of the tail to great extent 

 orange red. The female from Piganta has a very thin and 

 poor tail, but the bright orange-coloured tips of the new 

 hairs are to be seen between the bases of the remaining old
