(3) A laigc-to()tlK(l and very broad-jawed form, //. c. 

 guiueensh', inlial)its the eountrics i'rorn Conio River to 

 Lil)eria. Tliis area is a direct western continuation of tlic 

 region inhabited l)y K. c. centra/is, and, in accordance with 

 tliis tact, //. c. f/uincensis is nothing bnt an "exaggeration " 

 of//, c. centralis-, one ot" the chief characters of centralis, 

 the I'.rge nnixiilary width, linds a climax in (/uineeusis. 



(l) Angola is. geograi)hically, intermediate between tlie 

 areas of //. c. ti/juciis and //. c. centralis; and wc find in 

 Angohi a representative of the cajjcr type, //. c. anyolensis, 

 which in ahnost every respect is thoroughly intcrmcvliate 

 between tiie two races. — The geographical position of Angola 

 is such as to have invited H. c. t;/picus to immigrate from 

 east (Zand)csi Valley), //. c. centralis to immigrate from 

 north-east (Congo Valley); thus we find in Angola three 

 forms of //. coffer : not only //. c. unyolensis, the predominant 

 form, but also //. c. ty picas and H, c. centralis. 



(5j In the Guineau coast-iegion, from Benito River to 

 Liberia, lives a repre>entative of the cqlf'er type, //. beatus, 

 which in its cranial and external characters is so sharply 

 separated from all the foims ju.st menticuied that we have no 

 other choice than to regard it as a di>«tinct species. 



(6) Finally, iii the region inhabited by H. c. (/nineensis and 

 H. bealas, from Old Calabar to the (iold Coast, we find the 

 very different //. fuliyinosus. It has been necessary to give 

 an account of this species in the present paper, owing to its 

 confusion with //. coffer. Bnt it belongs to a ditlerent group 

 of the genus. 



The probable phylogeny of //. caffer, heat as, nud fulifjinosus 

 will be discussed in a subsequent paper, on some Oriental 

 species of Hipposulerus.
