E. LÖNNBERG, MAMMALOGY OF ECUADOR. 69 



From a geographical point of view this identification is 

 quite natural as Ph. 1. pictus is known from northerii Ecua- 

 dor before, but the original description suits it only with 

 regard to its first part. On the other hand the lower side 

 and the legs agree better with the description of those parts 

 of Ph. 1. senex Thomas. The type locality of the latter is 

 Mindo only 12—15 km as the crow flies south from Gualea. 

 But from Mindo this Museum possesses another specimen 

 presented by Consul Söderström at an earlier opportunity 

 and this ought thus to be the true »Ph. 1. senex», because 

 it is not possible to expect two different races of the same 

 species at the same locality. Now, however, the Mindo spe- 

 cimen shows several discrepancies from the description of 

 Ph. 1. senex. Among other things the lower side is almost 

 wholly white from chin to inner side of hindlegs, and the 

 mesial dark streak of the head is very well developed. I 

 think therefore that the colour variation is so great that 

 »pictus» and »senex» can be united, and the first of these 

 names has a slight priority.

1 J*, 10/7 1912, »Jacuehagen»(?), 5,000 feet. 



With regard to its colour this specimen agrees quite well 

 with Thomas' description of this subspecies, but with regard 

 to the variation of these animals it is difficult to express 

 any opinion about its value.
