Show 492 MR. ST. G. MIVART ON THE LEMURS. [ Myy 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 m e that he has now specimens of almost all the species in spirit, as well as skeletons, and even foetuses. 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 scientific 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 the 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. minor, 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 m e 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 coquereli (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 C. 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 % Cheirogaleus milii, but since erected by him into the type of bis new genus § Opcdemur. 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 removed from that proximity to Lemur which I assigned to it in 1864, and be relegated to the vicinity of Galago, as has been donejl by Professor Alphonse Milne-Edwards, in accordance with the elon- * P.
