regarded as synonymous with paca, being based on a female 

 of the original species only. Thomas has expressed a similar 

 supposition when describing C. sierrae, but he had then only 

 a female specimen of his new species. Novv he has in a 

 letter kindly confirmed the conclusion made above. 



If the descriptions of alpine Pacas by Stolzmann, Tho- 

 mas and the present author not are considered just now, 

 there appears only to be two more subspecies of Paca known 

 viz. »Agouti paca virgatus» Bångs and »Cimiculiis paca nel- 

 soni» Goldman, the former from Divala, Chiriqui and Pa- 

 nama, the latter from Vera Cruz in Mexico to Guatemala 

 and Honduras. J. A. Allén has låter (1916) recorded C. p. 

 virgata from western Colombia. 



It is thus of interest to find in the present collection 

 some big Pacas resembling C. p. virgata, but in some parti- 

 culars also differing from the same, so that it appears ne- 

 cessary to distinguish them with a subspecific name to avoid 

 confusion. I therefore venture to call them: 



Coelogeiiys paca guanta n. subsp. 



1 ^ old (type), 1 $ juv, Vs 1919 Gualea, 5,000 feet; 1 

 ^ old (skull only) 1918, Gualea, 3,500 feot; 1 $ ad., ^^Vg 

 1918, Pacto below Gualea, about 3,000 feet. Native name: 

 »Guanta». 



Bångs remarks, that the subspecies virgata differs from 

 the Brazilian form in being larger and in having the second 

 stripe on the sides much less broken up into spöts. Inthese 

 respects the present form agrees with virgata, but the author 

 quoted adds also that his subspecies has all the spöts above 

 the two lateral stripes smaller and the palate narrower than 

 the Brazilian form, but this is not the case with the present 

 specimens, but ratber the opposite. 



The general colour of this Paca from Gualea agrees with 

 that of the typical form, and the pattern is also essentially 

 alike. The two white side-stripes are well developed, and 

 the lower of them is separated from the white of the belly 

 by a broad dark band (unlike nelsoni). Above these lateral 

 bands there are as usual two rows of white spöts the lower 

 of which reaches from the sides of the neck to posterior end
