of the body, while the upper is confined to the posterior 

 half of the body. The spöts of which these rows consist are 

 comparatively large with a vertical diameter of 10 — 12 mm. 

 Below the lowermost of the lateral bands there is in the 

 inguinal region and across the thigh a short series of spöts 

 which especially in the female specimens have a tendency 

 to become confluent to a band which, however, anteriorly 

 soon is löst in the white of belly. 



The pelage is very thin and scanty. Especially in the 

 females the skin can be seen between the hairs everywhere, 

 but also in the male on the belly and the back, less on the 

 flanks.

As the type of virgata was an old male the cranial mea- 

 surements of the same communicated by Bångs are directly 

 comparable with those above. It is thus found that the 

 Paca from Gualea has a longer skull, with longer nasals, 

 longer palate etc. The palate is also comparatively much 

 broader and it is of importance to note that the present 

 form in this last respect approaches the Brazilian Paca. The 

 molars are also larger than those of virgata. This is visible 

 even in the smaller female skull.
