 London 1870, p. 828. We think is necessary to repeat 

 these also: 



"Notes on Hapalemur simus, a new species living in 

 the Gardens of the Society. By Dr. J. E. Gray, F. R. 

 S. etc. 



"(Plate 52)." 



"Every day, as the Osteology of the species is more 

 studied, brings to our knowledge the fact that Mammalia 

 Avhich are so alike in external appearance as not to be 

 distinguishable, prove on the examination of the bones, 

 and especially of the skulls, to belong to very distinct 

 species ; and some even , as in the leaf nosed Bats and 

 American Tapirs, prove to be very distinct genera. The 

 animal I am about to bring before the Society is an 

 example of this kind among the Lemuridae. Mr. Bartlett 

 during the autumn brought to the British Museum a Lemur, 

 which had died in the Society's Gardens to be determined , 

 that its name might be entered in the list of recent 

 accenssious ; and I agreed to purchase it for the collection. 

 On the casual inspection of the animal in its dead state, 

 I believed it to be a large specimen of Hapalemur griseus. 

 The preserved specimen and skull were exhibited on No- 

 vember the first. On examining the animal before it was 

 placed in the public room of the British-Museum collection, 

 I was convinced , that it was of a very distinct species 

 from Hapalemur griseus, then in the Museum, and I have 

 therefore sent to the Society the following notes, showing 

 the distinction of the two species. 



"I. Nose tapering , narrow in front. Skull — nose 

 tapering narrow in front; palate dilated behind; series of 

 grinders converging in front; lower jaw broad and strong 

 in front, with a long symphysis. Hapalemur. 



"Hapalemur griseus. 



"Hapalemur griseus, Sclater , Proc. Zool. Soc, 1863, 

 p. 161; Mivart, ibid., 1864, p 613, fig., skull (copied, 

 Catal. Monkeys etc. B. M., p. 77)."
