Mexico, and the State of Vera Cruz may be considered as the 

 type region of the species. 1 



The later names given to the Mexican species must be 

 treated as synonyms of N. narica, none of them being dis- 

 tinguishable from it by any of the assigned characters or 

 localities. 



The material available for examination shows that the 

 Coatis from widely separated localities in Mexico and Central 

 America vary greatly in general coloration and size, in the 

 relative size of the teeth, and in the size and shape of jthe 

 audital bullae, which variations form a basis for the separation 

 of the group into a considerable number of geographical forms, 

 in addition to those already recognized. 2 Several are here 

 indicated, as follows: 



Nasua narica panamensis, subsp. nov.

In coloration not readily distinguishable from N. narica bullata, 

 being very dark and highly colored, but much smaller, and with the 

 bullae of the usual size for the narica group. Top of head, nape, and

shoulders rusty brown; anterior half of back yellowish gray brown, 

 darkening on the posterior half of the back and rump to dusky brown, 

 the hairs tipped with yellowish gray; ears and sides of shoulders yel- 

 lowish white; feet and tail dark brown, the latter darkening apically.
