 It is at present impossible to make a satisfactory deter- 

 mination of every one of these squirrels, which show a wide 

 range of colour-variation, especially in the amount and in- 

 tensity of the bufFy of the under surface. The ns.mQ paraensis 

 seems to be the best to use provisionally for them until they 

 have again been revised with much further material. 



35. Microsciurus manarius, sp. n. 



c? . 85, 86. Acajutuba, Rio Negro, near its mouth.
