i, and pi. x, fig. 5), apparently agreeing with it in size, but differ- 

 ing from it in coloration. The type of M. minuta was from 

 " Capella-Nova, dans le Bresil," on the upper Amazon, but a 

 second specimen, still darker in color, from the Province of 

 Bahia, was also referred to it by Gervais. 



The single specimen on which M. hypoleuca is based unfor- 

 tunately lacks the skull. It differs from descriptions of M. 

 minuta by Gervais and Dobson in the yellowish white instead 

 of grayish white underfur above, and in the clear white instead 

 of ashy underparts.

This species is based on six specimens, only one of which 

 (taken as the type) is adult, and this unfortunately lacks the 

 skull. Although the immature examples almost equal the adults 

 in size (the forearm ranging from 54 to 56 against 60 in the 

 adult), four out of the five still retain the upper milk incisors.
