 ON SOME RARE AND INTERESTING MAMMALS.

Dec. 1884. 



Hapalemur griseus and Hapalemur simus. 

 (Plate 1 and 2). 



lu the Proceedings of the Zool. Soc. of London for this 

 year (1884) Mr. Beddard wrote a very interesting paper 

 regarding some points of the structure of Hapalemur simus. 

 On page 392 he says a few words touching the differences 

 between the skulls of H. simus and H. griseus. He says 

 that he was able to verify the late Gray's statements (with 

 regard to the differences in the skulls of the two species) 

 with a single exception, and finally states that it seems 

 to him that Gray was right in believing that Schlegel's 

 figure of the skull of Hapalemur griseus was in reality that 

 of Hapalemur simus. 



Being able to settle this question it seems to me that 

 it is my duty to fixe for a moment again the attention of 

 the naturalists upon this matter. 



At the time as the late Schlegel wrote his Monographie ., 

 entitled Simiae , our Museum was not in the possession of 

 a specimen of Hapalemur simus and at that time Schlegel 

 never had had a skull of the named species in his hands. 

 I can testify this as I personally assisted Prof. Schlegel
