new African Mammal s. 107 



Cricetomys gamhianus proparator, subsp. n. 



A Cricetomys about the size of typical gamhianus, less 

 brightly coloured, major part of tail white, and having 

 markedly larger teeth. 



Fur rather softer than in emini, 15 mm. long on back ; 

 individual hairs with basal two-thirds greyish white, apical 

 ihird brown. General colour on the Hanks "fawn," much 

 darker on the middle of back. Anus and legs rather darker 

 than flanks, whole hand and toes white. Almost three-fourths 

 of tail white. 



Skull with even stouter teeth than in emini, palatal foramina 

 shorter, only slightly larger than in gamhianus (s. s.), pre- 

 m axillary suture cutting foramina at their posterior extremity 

 (often at their centre in gamhianus). 



Dimensions of type : — 



Head and body 350 mm. ; tail 418 ; hind foot 72 ; ear 42. 



Skull : greatest length 76 ; basilar length 63 ; zygomatic 

 breadth 34; nasals, length 32; palatal foramina 7*5, dia-

Hah. East Ruwenzori. Alt. 6000 feet. 



Type. B.M. no. 6. 7. 1. 63. Original number 612. Col- 

 lected by R. B. Woosnam, 1st January, 1906. Presented by 

 the Ruwenzori Exploration Committee. 



The very large proportion of white tail-length, dull colora- 

 tion, and the skull-characters noted above serve to distinguish 

 this from any other form of Cricetomys. 



In order to determine some specimens recently received by 

 the Natural History Museum from Mlanji in Nyasalaud all 

 the specimens of P. hrucei were laid out, and it then became 

 evident that series of specimens from four different localities 

 representing distinct geographical races required names. 



Procavia hrucei hi?idei } sp. n. 



A Procavia of the Heterohyrax group, differing from 

 P. hrucei by its darker and redder colouring and by the 

 formation of the posterior palate. 



Fur medium, 25-27 mm. on the back. General colour 

 above " Mars-brown " ticked with whitish; individual hairs 

 pale seal-brown fading to russet, subapical 3—5 mm. cream- 

 buff, very short black tip. Belly and chest pure white, chin 

 and throat tending to become grey (though pure white in 

 some cases). Face coloured like back, but the obsolescence
