Sylvisorex gemmeus infuscus, subsp. n. 



General characters as in true gemmeus, but colour of body 

 much darker, near " fuscous " of Ridgvvay. 



Dimensions of type (measured in flesh) : — 



Head and body 65 mm. ; tail 73 ; hind foot 135 ; 

 ear 8. 



Skull : condylo-incisive length 17*5 ; breadth of brain- 

 case 7*7 ; upper tooth-series 7'6 ; p^-m 2 3*8. 



Hab. Bitye, Ja River, S. Cameroons. 



Type. Adult male. B.M. no. 13. 9. 12. 4. Original 

 number 642. Collected 17th December, 1912, by G. L. 

 Bates. 



Erinaceus algirus caniculus, subsp. n. 



Similar in essential characters to true algirus, but while 

 E. a. algirus of Morocco and Algeria is comparatively dark 

 above and partly or wholly dark below, and E. a. vagans of 

 the Balearic Islands (and Spain?) is light above and wholly 

 white below, the present form is even lighter than vagans 

 above, but its face and lower surface are partially brown, as 

 in algirus. 



Spiny area white or cream-white, the dark rings to the 

 spines scarcely showing, their light tips from 5-7 mm. in 

 length. Furry area with the edge bordering the spines 

 brown all along, from the crown backwards along the flanks 

 to the hind limbs. A broad band across the muzzle from 

 cheek to cheek brown. Hands, hinder portion of belly, and 

 whole of hind limbs also brown. 



Dimensions of the type, measured in flesh (immature) : — 



Head and body 190 mm.; tail 27; hind foot 35; 

 ear 30. 



Skull : greatest length 51. 



Skull of an old female : condylo-basal length 56*5 ; 

 zygomatic breadth 37 ; intertemporal constriction 13 # 8 ; 

 palatal length 34 ; upper tooth-series 27*8. 



Hub. Eastern Canary Islands. Type from Toston, Fuerte- 

 ventura. 



Type. Immature male. B.M. no. 13. 7. 26. 11. Original 

 number 1. Collected 9th May, 1913, by Mr. D. A. 

 Bannerman. 



It is not improbable that hedgehogs from the desert regions 

 of Africa opposite the Canaries will also prove to be this 

 pale form of E. algirus.
