skin, skull, and lower jaw now in the Natural History- 

 Museum, London. The type of Okapia Johnstoni, Sclater, 

 namely the two pieces of skin (" bandoliers") from the hind 

 limbs, is also preserved in this Museum. 



Certainty as to the distinctness of these two species and a 

 complete diagnosis of their characters, if they should prove 

 to be, as now supposed, distinct, can only be based on the 

 examination of a large series of specimens.

Palreontologia Indica. New Series. Yol. I. Part 3. Fauna of the 

 Miocene Beds of Burma. By Fritz Noetlinq, Ph.D., F.G.S., 

 Palaeontologist, Geological Survey of India. Folio. 378 pages, 

 25 plates. Calcutta : Geol. Survey Office. London : Kegan 

 Paul & Co. 1901. 



The author explains that the fossils here described, besides in- 

 cluding those collected by himself from the Irrawadi series and 

 other beds, comprise some collected by the late Mr. Grimes and 

 others by Messrs. Tbeobald aud Fedden in Lower Burma some thirty 

 years ago. He foinid that the want of any reliable hterature on 

 Burmese palaeontology was not relieved by any of the published 

 works on Indian fossils. The corals and echinoids are too rare in 

 Burma for Duncan and Sladen's monographs on those of Western 

 India to be of service, and Sowerby's descriptions of Cutch fossils 

 are not sufficiently distinct. The memoir on the fossils of the 

 Nummulitic group of Sind by d'Archiac and Haime he found to be 

 " worse than useless," the fossils of different formations being con- 

 fused. The type fossils require to be revised and carefully compared 

 with others of autbeuticated horizons. 



Martin's ' Tertiiirschicbten auf Java,' however, has been of great 

 use to him ; and, following Stoliczka's suggestion that the fauna of 

 the Burmese Tertiary System should be compared with the living 

 fauna of the Indian Ocean, F. NoetUng has been able, thanks to 

 Major Alcock, to study the great collection in the Indian Museum 

 with highly satisfactory results. 



Thus a new line of research has been opened out in the study of 

 the Indian Tertiary System, affi^rdingsome higbly interesting "views 

 regarding not only the origin of the recent fauna of the Indian 

 Ocean, but also of the relation the Miocene of India-Burma bad 

 with the older Tertiary System of Europe and the recent fauna of 

 the Western Pacific. In fact, I think that one of the most im- 

 portant of my results," says Mr.Noetling, "is the proof of a migration 

 of species from Europe in an eastern direction, which commenced 

 with the Eocene and probably lasted through the Miocene— a migra- 

 tion which still continued in an eastern direction during the Miocene
