492 MR. ST. G. MIVART ON THE LEMURS. [May 20, 



lication a magnificent work on the Fauna of Madagascar, in which 

 no less than 300 plates are to be devoted to Mammalia. He also 

 tells me that he has now specimens of almost all the species in 

 spirit, as well as skeletons, and even fetuses. 



These treasures are due to the noble devotion to science of M. 

 Grandidier, who has spent so long a period in persevering and 

 arduous explorations in Madagascar, and who now places the scien- 

 tific world under yet further obligations to him by causing the 

 copious illustrations just referred to to be executed at his own cost. 



It would thus be labour lost, and useless occupation of space in 

 the Society's ' Proceedings,' to attempt here in London a revision 

 of the species of Cheirogalei. I will therefore merely make a few 

 passing observations. 



In tbe first place it may be useful to record where the types of 

 various species are deposited. 



The typical specimens of the so-called species (1. typicus, 2. mi- 

 nor, and 3. smithii) are preserved in the British Museum. 



Those of 4. milii, 5. furcifer, and 6. pusillus are in Paris; and 

 7. myoxinus is in Berlin. 



Professor Milne-Edwards informs me that the species which have 

 been termed smithii, minor, myoxinus, gliroides, rufus, and pusillus 

 are all one — also that, as I had suspected*, Ch. milii and typicus are 

 of the same species, and that the major of Geoffroy St.-Hilaire and 

 the adipicaudatus of M. Grandidier are also the same species as 

 milii — likewise that M. Grandidier's C. samati is the medius of 

 Geoffroy, but that coquere/i (which M. Grandidier was the first to 

 describe under that name) is a good species. 



The specimens added to the national collection are, amongst 

 others : — 



Four specimens attributed by Dr. Gray to his species 0. typicus 

 and four specimens attributed by him to his species C. smithii 

 (since called, in his Appendix to Cataloguef, Azema smithii), also two 

 specimens called by him in the British Museum Catalogue % C'hei- 

 rogaleus milii, but since erected by him into the type of his new 

 genus § Opolemur. 



The three other new genera also instituted by Dr. Gray (namely 

 Murilemur\\ for Cheirogaleus minor, and Phaner*^ for Cheirogaleus 

 furcifer, and Mirza** for C. coquereli) I cannot regard as having 

 any real claim whatever to distinctness, any more than the genus 

 Prolemur instituted by him for Hapalemur simusff. 



All these matters, however, will soon probably be set at rest by 

 the publication of the Fauna of Madagascar. 



As to the position of the genus Cheirogaleus, it must, I think, be re- 

 moved from that proximity to Lemur which I assigned to it in 1864, 

 and be relegated to the vicinity of Galago, as has been done|| by 

 Professor Alphonse Milne-Edwards, in accordance with the elon-
