Three specimens: Medje, 2 (cT and 9 adult), January 24, 1909; 

 Niapu, 1 (cf adult), November 28, 1913. 



Collectors' measurements of the Medje specimens: Total length, 

 d 71 322 mm., 9 337; head and body, <? 144, 9 152; tail vertebrae, cf 

 178, 9 185; hind foot, tf 35, 9 35; ear, & 14, 9 14. 



Skull, same specimens : Greatest length, d 71 37.3, 9 38.2; zygomatic 

 breadth, not measurable. 



The Niapu specimen is a little smaller and less mature. 



Entire pelage, including feet and tail, olivaceous gray, except ventral 

 surface, which is washed with ochraceous medially, the color of the sides 

 extending over the lateral third of the ventral area from axillae to loins. 



Compared with two specimens of Mthosciurus poensis (No. 8639, 

 Kribi, Cameroon, and No. 15667, Mus. Comp. Zool., Lolodorf, 

 Cameroon), with which they closely agree. Larger series from the two 

 regions (Cameroon coast and Upper Congo) might indicate an appreci- 

 able average difference not indicated by the material now available. 



'The total number of localities at which these forms were collected is 24.
