uciv Mammati from Lalce Chad and the Congo. ;'7l 



shade ; two dark (almost black) streaks from the shoulders 

 to the tail, broken at regular intervals, from the middle of 

 the back backwards, by whitish-buff spots; outside these ou 

 each side two other dark stripes, not extending quite so far 

 forward as the median pair, broken by five and four pale 

 s))ots (the general effect is that of a rather regular chess- 

 board pattern on the lower back, rump, and haunches). 

 Individual hairs of the back, outside the pattern-area, grey at 

 their bases, then a bright buff (almost orange) with black 

 tips, the black ti|)s varying very much in length, from two 

 thirds the whole length of the hair to 1 or 2 mm. only at the 

 distal end. Fore feet dark-coloured, clothed with short 

 hairs which are black at base and tip, with a median bright 

 buff ring ; hind feet still more sparsely clothed with even 

 shorter hairs of the same pattern. Tail at base black for a 

 short distance (30-o5 mm.), then white and clothed with 

 sparse, very short, white hairs. 



The measurements of the type specimen are as follows : — 



Head and body 314 mm. ; tail 222; hind foot 80; ear HO. 



Skull : greatest length 67 (circ.) ; length of nasals 19 ; 

 length of frontal suture 27*5 ; greatest breadth 35 ; inter- 

 orbital breadth 22 ; length of palate 35 ; length p^ to m^ 

 inclusive 20. 



Ilab. Beritio, Welle River. 



Type. Old male. Original number 58. Collected Feb- 

 ruary 14th, 1906, by Mr. Boyd Alexander. (Four specimens 

 and a young skull examined.) 



The present species is at once separable from all others 

 except Stuhlmanni by its white tail, and from that it differs 

 by its paler brighter colouring. In the type of Claudiy though 

 a very old animal, the chessboard pattern on the back is 

 brightly and clearly marked. 



We have named this handsome species and the duiker 

 described further ou in honour of Major Claud Alexander, 

 the leader of the Alexander-Gosling Expedition up to the 

 time of his death. 



Erinaceus spiculus, sp. n. 



A medium-sized hedgehog, belonging to the group with 

 four toes, with the colouring and short slender spines of 

 albiventris. 



Spines short (15 mm.), slender and absent on the summit 

 of the crown along a band about 5 mm. broad. 



Ear of medium size, smaller than in Adansoni from 

 Senegal, but larger than in the Soudanese albiventris. Hind
