definitely registered as Erinaceus albiventris subsp. pruneri." Again 

 he says, later on the same page, referring to albiventris: ''This species is 

 found to the south of Khartum," and "ranges into Somaliland and as 

 far south as Kilima-nyaro." Within this region, since 1902, two forms 

 (E. hindei Thomas and E. albiventris sotikae Heller) in addition to pruneri 

 have been recognized, 1 and two more are added in the present paper, 

 both from Farad je, northeastern Belgian Congo. 



As stated above (p. 9, footnote), Thomas and Wrough ton in 1907, 

 in describing their Erinaceus spiculus, referred to Sudanese specimens 

 as typical of E. albiventris. In view of the complications of the case, it 

 seems to me preferable to place Erinaceus albiventris permanently in the 

 list of unidentifiable species, it having no type locality and being speci- 

 fically unidentifiable from the original description, although the type 

 appears to have been preserved in the Munich Museum. 2 Senegal (or 

 Senegambia) and Sudan (or Sennaar), the rival suggested type regions, 

 are far apart, with E. adansoni representing the former and E. pruneri 

 the latter as well established species. Under this ruling the two forms 

 from Farad je are described as new. 



Atelerix Pomel 

 Since the foregoing was prepared for the press a paper by Oldfield 

 Thomas, on 'The Generic Divisions of the Hedgehogs' (1918, Ann. Mag. 

 Nat. Hist., (9) I, February, pp. 193-196) has appeared, respecting which 

 a few notes are here appended. The old genus Erinaceus is divided by 

 Thomas into five genera, which, with their designated genotypes, are as 

 follows: 



1. Erinaceus Linne, 1758. Genotype, E. europseus Linne. 



2. Mihechinus, new genus. Genotype, E. algirus Duvernoy and 



Lereboullet. 



3. Atelerix Pomel, 1848. Genotype, E. albiventris Wagner. 



4. Hemiechinus Fitzinger, 1866. Genotype, E. platyotis Sundevall. 



5. Parechinus Trouessart, 1879. Genotype, E. micro-pus Blyth. 



Although each of these groups is represented in Africa, only 

 Atelerix and Mihechinus come geographically within the scope of the 

 present paper. Atelerix was proposed by Pomel (1848) as a subgenus of 

 Erinaceus, with the statement "4 dactylus" as the entire diagnosis. No 

 species was referred to it, and no geographic range was indicated for the 



iSince this was written Thomas has added a third from Kilimanjaro as Atelerix kilimanus (1918, 

 Ann. Mag. Nat. Hist., (9) I, March, p. 232. 



2 As stated above (p. 10, footnote), the type was probably critically studied by Anderson prior to 

 1895, together with the type of pruneri, leading to his assignment of the type locality of albiventris to 

 Senegambia, and to his later recognition of pruneri as an eastern subspecies of albiventris.
