SETIGER SÉTOSUS. 143 



individual — measuring about 10 c. m. — before me, has 

 the bases colored like the rest of the quills, viz. reddish 

 brown , the points being white , but several quills are entirely- 

 reddish brown. In our largest specimen — measuring about 

 22.5 c. m. — all the quills bear a rather narrow subterminal 

 black ring ^) : another individual — measuring 14 c. m. — 

 shows many quills Avhich are black , except towards the base. 

 Another again , of the same the length as the former , has 

 the white quills embellished with a brown sub terminal ring. 

 Upperparts of head , hands and feet are covered with smoke 

 brown hairs , the remaining parts of the body being straw 

 colored. Whiskers black, brown or straw-colored. Hairs 

 of the eye-brows black. 



Upper jau\ The incisors are separated from each other 

 by intervals, the two middle are the largest, — much 

 more developed than in the other Madagascar Hedgehogs — 

 subcylindrical , perpendicular, and placed at the apex of 

 the jaw ; the two other ones are shaped as the former , but 

 less developed in all proportions, though stronger than 

 in the following species. Separated by a small space suc- 

 ceed the canines , simular to the incisors , but longer and 

 bearing a small posterior notch — in very old individuals 

 the incisors too are notched. The molars , separated by 

 a space from the canines , are crowded , which is not 

 the case in the other species. 



Lower jaw. The hindmost incisors are the longest , for the 

 rest they are shaped as the other ones and obliquely di- 

 rected forwards ; the canines and incisors are crowded and 

 notched. The canines bear two notches, for the rest sha- 

 ped like the hindmost incisors , but larger in all proportions. 

 The first false molar is separated from the canines and the 

 other molars by a narrow space. The other molars are 

 crowded. 



The muzzle, ears and tail as in the common Erinaceus 

 europaeus. 



1) Both this sjiecimen and the following belong to the black variety , introduced 

 by Is. Geoffrey St. Hilaire as a distinct species under the name of nigrescent-
