The difficulty is now to place some of these names cor- 

 rectly, and to decide which is the proper name of the Grison 

 from Ecuador. It may lie near at hand to assume the latter 

 to be identical with the last mentioned G. andinus as both 

 originate from western South America and from the Andes. 

 This is, however, not the case. Neither in colour, nor with 

 regard to cranial dimensions do they agree, G. andinus being 

 considerably smaller. 



On the other hand the cranial measurements of the 

 Ecuador specimen very nearly agree with the corresponding 

 ones of a Grison from S:a Catharina, Brazil as the foUowing 

 table of measurements proves, and at the same time they 

 agree very well with those which Nehring has published^ 

 for females of the animal which he named Galictis allamandi 

 Bell in his paper 1886.

The female Grison, on which Bell based the name -»alla- 

 mandi», was kept in confinement, and it is therefore prob- 

 able that the measurements of its skull not are quite similar 

 to those of wild specimens of the same kind. Nehring has 

 published them (1. c), and they prove to be a little smaller 

 (especially the mastoid breadth) than those recorded above 

 as well as than those of wild specimens published by the 

 author quoted. The origin of the type of »allamandi» does 

 not appear to be well known.
