12 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 6 1 



gated by longer annulated hairs ; head more grayish, the hair covering 

 chiefly annulated black and white ; muzzle and chin with black hair 

 chiefly ; back of ears black. 



Measurements. — Head and body, 560 ; tail, 440 ; hindfoot, 125 ; ear, 

 20. Skull, condylo-basal length, 1 10 ; zygomatic breadth, 525 ; post- 

 orbital constriction, 22 ; width of palate across PA1 4 , 35 ; length 

 of upper tooth row to front of canine, 44.5 ; condylo-incisive length 

 of mandible, 79 ; height at coronoid, 24 ; length of last lower molar, 

 7.8 ; breadth of last lower molar, 5. 



Teeth much worn in type, the cusps of the molars worn down to 

 the general tooth level, so that the cusp formula? cannot be deter- 

 mined. Skin tanned and preserved in a flat condition. A series of 

 skins of ibeanns from the vicinity of the type locality are blackish, 

 the underfur showing only on sides and where it is grayish and not 

 buddy. The white-tailed mungos inhabiting the coast district of 

 East Africa is a light colored race like leucurus of the north with 

 the large bodily size of the southern race, grandis. The last lower 

 molar exceeds in width that of grandis by three millimeters, but the 

 skull is almost the exact size of the type of the southern race. 



BDEOGALE CRASSICAUDA OMNIVORA, new subspecies 

 Northern Four-toed Mungoose 



Type from Mazeras, British East Africa ; adult female, Cat. No. 

 182275, U. S. Nat. Mus. ; collected by Edmund Heller, Dec. 21, 191 1. 

 (Original No. 2588.) 



Characters. — Resembling Bdeogale crassicaitda crassicauda in size 

 and proportions, but color of tail and feet darker, black rather than 

 seal-brown ; body color lighter owing to the scantiness of black tipped 

 hairs which allows the buffy underfur to predominate, giving the coat 

 a grizzled effect. This race differs decidedly from tenuia of Zanzi- 

 bar, which is a short tailed species with a uniform brown body color- 

 ation and smaller body size. 



Measurements of the type in the flesh. — Head and body, 420; tail, 

 245 ; hindfoot, 81 ; ear, 34. Skull fully adult, all the sutures being 

 obliterated, but the cheek teeth have prominent unworn tubercles or 

 cusps. Condylo-basal length, 85 ; basal length, 80 ; zygomatic breadth, 

 46; mastoid breadth, 33; interorbital width, 18; post orbital con- 

 striction, 14; palatal length, 50; width across PM 4 , 28; length of 

 upper tooth row, 40 ; width of M\ 7. 



Besides the type there is another adult female in the collection 

 from Mazeras. This specimen is slightly larger with more worn
