and the pale tint is not so sharply defined fi'om the yellowish tint 

 of the sides of the body. The bands on the tail vary in thickness, 

 but are almost parallel-sided all round and the intervening space 

 is marked with a narrow ring which, although varying in distinct- 

 ness, is always apparently detectable ; the under side of the tail is 

 not white and only a little paler than the upper. The example 

 in the British Museum, alleged to have come from )Sierra Leone, 

 does not differ appreciably from the type and the two from the 

 Benito River. Its locality is probably erroneous. 



The type and only known example of Poiana richardsoni 

 ochracea has the gi-ound- colour a richer and more rusty yellow 

 than in the others. The spots on the body are very small and 

 widely spaced, and show signs of fusion into definite lines only 

 upon the dorsal area between the shoulders. The caudal rings 

 are narrow, much nai-rower than the interspaces, which have no 

 intermediate stripe. The ventral surface of the body and tail and 

 the insides of the limbs are yellowish and only a little paler than 

 the dorsal surface. 



The three subspecies may be distinguished as follows : — 



a. Spots small and widely spaced ; ventral surface yellowish, 



scarcely paler than the dorsal ochracea. 



a}. Spots mostly large and therefore more closely-set ; ventral 

 sui-face white or whitish. 

 h. Dorsal surface a dusky yellow-brown ; ventral surface 

 yellowish or creamy white, gradually blending with 

 the yellowish hue of the sides ; under side of tail not 

 white, hardly paler than the upper; rings on tail 

 regular and annuliform, with intermediate rings more 



or less apparent richardsoni, 



&\ Dorsal sui-face a lighter clearer yellow ; ventral surface 

 milk-white and sharply defined from the yellow hue 

 of the sides of the body ; under side of the tail white ; 

 tail-rings not regularly annuliform, somewhat tri- 

 angular in shape ; intermediate rings not apparent.
