pp. 13 & 31. 
Lasiopus, 1. Geoff. Cour. d’Hist. Nat. des Mamm. 57, 1835. 
Body compressed. Legs rather long. Fur grizzled. Tail conical, 
bushy. Toes 5—5. Claws rather elongate, sharp. The greater part 
of the soles of the hind feet are covered with hair. Teeth 40; false 
grinders = flesh-tooth triangular ; tubercular grinders =, 
The most Viverrine form of this subtribe. 
M. Geoffroy separates this genus on account of its peculiar denti- 
tion, which he describes :—false grinders 3/4, true 1/1, tubercular 2/1 
(Mag. Zool. 1839, p. 7). M. Geoffroy’s figures are lower on their 
legs and more vermiform than our specimen of I. albicauda. 
Dr. A. Smith, when first describing this species, observed, ‘‘ Its 
teeth exhibit a slight difference in form, and are not so closely set as 
in the trueIchneumons. ‘This peculiarity, in addition to the state of 
the soles of the feet, may, when its manners and habits are better 
known, require it to be separated from the present genus’? (South 
African Quart. Journ. 52, 1834). 
‘Shorter and more robust, and stands higher on its limbs, than 
Herpestes.”’—A. Smith.
