but in the present specimen 59 mm; the greatest height of the 

 zygoma in the former 36, in the latter 31 mm. 



These clifferences are of course not very great, but consi- 

 dering that in addition to the different colour the smaller di- 

 mensions are to be found in an fully adult male and the larger 

 in a female, it appears to be the correctest view to regard the 

 Paca from Pichincha to represent a geographic subspecies 

 distinct from that of Merida. This is also supported by the 

 fact that other mammals as well are represented by different 

 subspecies in the Merida-mountains and on Pichincha, al- 

 though they display an analogous development in both loca- 

 lities in consequence of similar conditions of life. 



Sylvilagus andiims Thomas. 



Four specimens ef c? ?$ from Pichincha. About two 

 it is stated that they ha ve been collected a t an altitude of 11,000 

 feet at Nono, and on the two other labels Consul Söderström 

 remarks that this little Hare ranges from 7,000 to 14,000 feet, 

 and that it appears to be most abundant in the rainy season. 



All four specimens are typical andinus with the rufous 

 patch of the nape extending beyond the laid-back ears. The 

 brightness of the rufous colour appears to vary individually ; 

 it is richest in a female caught in March, but duller in speci- 

 mens obtained as well in Febr. as in May. 



The native name is stated to be »Correjo». 



Pudua mepliistopheles De Winton. 



De Winton: Proc. Zool. Soc. London 1896, p. 508. 



A buck which Consul Söderström considers to be about 

 tullgrown, and which is from the type locality Papallacta, al- 

 titude 12,000 feet, has simple spike-like antiers still in velvet 

 but härd. Their length from the well developed burr to the 

 tip is about 75 — 78 mm; the diameter of the burr about 23 

 mm.
