ensis, I failed to find these structures. I do not lay much stress 

 upon the value of this observation, since it is less satisfactory to 

 deal with dried skins than with the recently dead animal. But 

 the possibility must be borne in mind that these tactile hairs may 

 be less constant in the female of certain Lemurs than in the male. 

 And that, therefore, the character to which I refer as possibly 

 distinguishing the two species of Hapalemur — if it really does 

 distinguish the male from the female in H. simus — may not be of 

 great value as a mark of specific difference. The matter must be 

 settled later.

of H. simus seems to be longer in proportion to the body than in 

 the other species. The specimen of H. simus which I dissected 

 had a body-length (exclusive of tail) of 14 inches, it being thus 

 not much, if any, larger than H. griseus. But the intestinal 

 measurements were as nearly as possible double the length of 

 those of the example of H. griseus recorded by myself. In 

 H. simus the several lengths were as follows : — fSmall intestine 

 4 ft. 9 inches ; large intestine 2 ft. 4 inches. The alimentary
