34 Mr. O. Thomas on the Striped Squirrels 



The forms referable to this genus appear to be as follows : — 



1. Tamiscus bdhmi, Reich. 

 Sciurus boeJnni, Reich. Zool. Aiiz. ix. p. 315 (3836). 



Dark lines on back not deep black, but lightened by inter- 

 mixed greyish or buffy hairs. Edges of ears lighter than 

 general colour of head. 



Marimgu (Bohm), Mweru {Sir A. Sharjw). 



2. Tamiscus emini, Stuhlm. 

 Sciurus mini, Stuhlm. Mit Emin Pascha, p. 320 (1894). 



Dark lines of back strongly contrasted glossy black. 

 Edges of ears (proectote and antitragus) not lighter than rest 

 of head ; a small whitish patch behind them. 



Incisors not specially thrown forwards ; comparatively 

 thick, about 1'6 mm. in antero-posterior diameter at their 

 exit from the base in adult specimens. 



2 a. Tamiscus emlni emim. 

 Sciurus emini xigandce, Neuni. SB. Ges. Nat. Berl. 1902, p. 180. 



General colour strong olivaceous. Dark stripes variable in 

 breadth, the outer ones well marked, well over 2 inches 

 in length. 



Semliki River (Stithhnann, Carruthers) (type-locality) ; 

 Congo area westwards to the Ubanghi (Boyd Alexander), 

 "Welle and Ituri Rivers (Emin, Boyd Alexander, Christy, and 

 others), Ruwenzori and Fort Portal (Woosnam), Unyoro 

 (Ansovge), Businde, Uganda (Blaine), Entebbe (Jackson), 

 Kampala [Neumann). 



I fail to find any distinction between the series from the 

 Congo area and those from Uganda. The breadth of the 

 dorsal stripes, used by Neumann to characterize his subspecies 

 ugandce, proves to be absolutely variable in every locality, as 

 also do the sizes of the teeth and the bowing of the skull, in 

 which respects differences are observable between different 

 specimens. 



2 b. Tamiscus emini gazellce, subsp. n. 



General colour of true emini, but body-colour much paler 

 and greyer. Flanks near "dull citrine" of Ridgway, head 

 and .shoulders rather greyer. Proectote of ears coloured quite 

 like the crown, but the edge of the antitragus may be a little 

 lighter. Dark dorsal lines reduced in extent, the outer 

 narrower aud shorter, little more than an inch in length.
