LV. — Xeio Suhspfcifis o/' Profcoxeriis stan^eri, the Giant 

 Sqidrrd of E'lualorial Africa. By Oldfil:lu Thomas. 



(Published by peruiis.sioii of the Trustees of the Ih'itish .Museum.) 



The Miisomii series o? Proto.i'erna stanf/erl nou^ iimnbcrs 02 

 speciniejis^ raiigini;' from the CJohl Coast to Ktiviroiuln^ aii<l 

 from Ni<;eria soutliwarcis to N. An<^-ola. They are fairly 

 equally divided ainoiio- the 14 subspecies which appear to he 

 worthy of subspecific recognition. Ot" these four new ones 

 need description. 



The differences are merely of colour, as I can find no 

 cranial characters of any value. 



Pi'otoxerus stangeri dissomiSj subsp. n. 



Nearly allied to P. s. ehorivorus^ but paler througliont. 



Back with the light rings more bufiy than in ehorlrovus^ 

 less ochraceous, the resulting colour being an approach to 

 that of nordhofi, which Is still more yellowish. Shoulders 

 distinctly lighter than back. Under surface more whitish. 

 Crown dark hoary-grey, not abruptly separated. Lateral 

 line grizzled grey. Bnffy fringes of forearms well marked, 

 lighter than in ehorivorus. Hind limbs and feet bufly 

 ochraceous. Tail with the white tips of the hairs more 

 strongly contrasted. 



Hind foot of type 65 mm. ; greatest skull-length 67. 



llah. Ja Ttiver, Cameroous. Type from Bitye, 2U00'. 



Type. Adult female. B.M. no. 9. 10. 2. 20. Original 

 number 17. Collected 3rd September, 1908, by Mr. G. L. 

 Bates. Six specimens. 



This is one of the {aw cases where an animal of the Ja 

 Kiver, diaiidng eastwards, is definably ditlerent from its ally 

 of the Como and Benito rivers, draining- direct to the const ; 

 but the difference in general tone from Mr. Bates's exam[)les 

 of ehorivorus is quite well-marked. 



Prolo.cerus stangiri iwrreuf^^ subsp. n. 



A dark-coloured race from the AVclle, very like P. s. ehorl- 

 vorus of the West Coast. 



General appearance very much as in ehorivorus, conse- 

 quently much darker than in the ge(),<;ra[)liical neighbour, 

 notabilis. The back blackish, finelv licked witli ochraceous.
