NO. I NEW AFRICAN MAMMALS HOLLISTER / 



Measurements of type. — Skull : Greatest length, 105 mm. ; condylo- 

 basal length, 104; zygomatic breadth. 54; mastoid breadth, 37.1: 

 postorbital constriction, 20.2 ; lireadth of rostrum over canine, 20.3 ; 

 length of mandil)le, 69.5. Teeth of type and of a younger adult, 

 male from the type locality in which the molars are less worn, 

 measurements of the latter in parentheses : Upper row, including 

 canine, 39.8 (40.8) ; lower row, including canine. 44.8 (45.8) ; last 

 lower molar, 7.6x4.2 (7.7x4.5). 



Remarks. — This new subspecies of Mungos alhicaudus is based on 

 three specimens from the type locality and an additional skin from 

 Merelle Water, on the Marsabit Road. These four skins are all 

 lighter colored than any skins of ibeanus in the collection, and when 

 placed together the series as a whole is sharply differentiated from a 

 suite of seventeen skins of ibeanus collected at points along the 

 Uganda Railroad from Kavirondo to the coast.
