pruneri, a course followed by apparently nearly all subsequent authors. 

 But not by all, since von Heuglin 1 in 1867 gave a list of the species of 

 Erinaceus occurring in "Nordost Afrika" in which he included: "Erina- 

 ceus pruneri Wagner. Aus dem Sennaar." And Fitzinger 2 recognized it 

 as not only distinct from albiventris but as the type and only species of 

 his genus Peroechinus. In the original description of pruneri it is stated 

 merely that the specimens on which it was founded came in a collection 

 of mammals sent by Dr. Pruner from "Kairo." It is known, however, 

 that Dr. Pruner visited the Upper Nile region and there collected speci- 

 mens of hedgehogs that were sent to Wagner, 3 among them those on 

 which pruneri was originally based. 



It may be noted further that Sundevall, about the same time (see 

 below, p. 12), described his Erinaceus heterodactylus, 4 a species having 

 4-toed hind feet, based on specimens collected by Dr. Hedenborg in 

 "Sennaar," and that this species has always been synonymized with E. 

 pruneri by subsequent writers, both forms coming from " Sennaar." 

 As both have been referred by most authors to E. albiventris, it may be 

 that this fact has had an influence in the recognition of Sudan as the 

 type region of albiventris (or, more definitely, Kordofan, in the case of 

 pruneri) . 



To follow further the history of E. albiventris, from a geographic 

 point of view, Fitzinger, in 1867, 5 gave its Vaterland as "nicht mit 

 Sicherheit bekannt, wahrscheinlich aber Ost-Indien," and that of 

 pruneri as Kordofan. Dobson, in 1882, 6 gave the range of albiventris as 

 "Northern Tropical Africa (Senegambia, Sennaar)," and Anderson in 

 1895, 7 as extending from "Senegambia across Central Africa, south- 

 wards to Uganda and northwards to Somaliland." In 1902, 8 he stated: 

 "The specimen upon which Wagner founded this species [Erinaceus 

 albiventris] came, in all probability, from Senegambia," 9 and adds: 

 "The Nile Valley and East African specimens . . . may be more

 Wagner, E. heterodactylus Sundevall, E. adansoni Rochebrune. He added: "This species [albiventris] 

 has been obtained at the following localities: Senegal; Saint Louis; Cape Verd; Joal; MacCarthy's 

 Island, River Gambia [collectively =range of E. adansoni]; Accra, Fantee; Porto Seguro, Togo; 

 Gaboon; Kitui, Ukamba [type lor ality of E. hinder Thomas, 1907]; Tabora; Kas6; Kilima Njaro; 

 Wakilomi, District of Maka; Central Somaliland; Sennaar [E. heterodactylus]; Kordofan [E. pruneri]; 

 and region of Upper Nile."

9 This statement, doubtless, was based on his personal examination of the type in the Munich Mu- 

 seum, ashestatesin another connection (1895, Proc. Zool. Soc. London, p. 414) : "I may mention that I 

 have examined all the Hedgehogs preserved in the Museums of Paris, Frankfort on the Main, Munich, 

 Berlin, and London, and . . . some of the specimens described byTitzinger in the Vienna Museum."
