amining a skin of this animal, obtained by him in that district in 

 May 1862, which is now in the British Museum, where it has been 

 named Mycetes caraya. As might have been expected, it is de- 

 cidedly of a different species from the M. caraya of S. Brazil, 

 Paraguay, and Bolivia, being the most northern species of the genus, 

 while Mycetes caraya is the most southern. It differs from M. 

 caraya in its long soft hairs, which below, towards their bases, show 

 a rufescent tinge, in the hair on the face being inclined forward instead 

 of reversed, as will be seen in the accompanying figures, and in the 



Mycetes villosus.

colour of the female and young being black like that of the male. 

 Other differences would be, no doubt, found on comparison, which, 

 however, requires further materials for the purpose. But I have no 

 doubt of the distinctness of the northern species ; and I believed it to 

 be undescribed, until I compared it with the single imperfect stuffed 

 specimen in the British Museum upon which Mycetes villosus, 

 Gray*, was founded. This is stated to be from "Brazil;" but 

 I think it probable that there has been a mistake in the locality, and 

 that it is identical with the Guatemalan animal.
