IcTONYX erythraea de Win ton. 

 Red Sea Striped Weasel. 



Ictonyx erythraea (sic) de Winton, Ann. mag. nat. hist., 1898, ser. 7, 1, p. 248. 



The type locality of this species is Suakin on the Red Sea coast, and 

 its describer considers that a specimen from Somaliland represents 

 the same form. A male collected by Mr. A. L. Butler at Roseires on 

 the Blue Nile is also referred to this species by Wroughton (1911, p. 

 459). Two specimens were taken by our expedition — at Gabardi 

 and El Garef respectively, localities between Singa and Roseires. 



Erinaceus albiventris pruneri Wagner. 

 White-bellied Hedgehog. 

 Erinaceus pruneri Wagner, Schreber's Saugeth. suppL, 1841, 2, p. 23. 



Although apparently not uncommon, Hedgehogs were hard to ob- 

 tain. A live one was brought in by the natives at Fazogli who said 

 they occasionally came upon them, or found them hidden in hollow 

 logs or tree trunks. The dried spiny portion of the skin is sometimes 

 found, as if left by some animal that had eaten the rest. 



This species belongs to the group for which Pomel in 1848 proposed 

 the generic name Atelerix, type species pruneri. Fitzinger in 1867 

 gave the name Peroechinus to the same group of small hedgehogs 

 that lack the first hind toe. In the specimen from Fazogli the toes 

 are very short, hardly separate from the pad. The claw of posterior 

 digit 2 is largest, curved, and flattened. The remaining claws of the 

 hind foot are successively smaller, that of the third digit rather flat- 

 tened, those of the fourth and fifth compressed laterally. The face 

 from nose to between the eyes is thinly covered with short dark brown 

 hairs, and in life the skin is blackish. The hair of the forehead, cheeks, 

 and ventral surfaces is dull white, mixed on the ears, legs, and tail with 

 brown. This coloration separates it from the Senegambian albi- 

 ventris of which it is made a subspecies by Anderson and de Winton 

 in their Mammalia of Egypt. The spines are blackish, with white 

 tips, and a few along the sides are white throughout. 



We found nothing of the species senaarensis described from Sennar 

 Province, It belongs to the group of larger species with five well- 

 developed claws on the hind foot. According to Anderson and
