On a Collection ofBirds frorm Chna and Japan. 157the species Balcena marginata on three blades of whalebone,he says I have called it Eubalcena marginata-thus confound-ing it with the whales with brittle and coarse whalebonewhereas the chief reason that induced me to consider the bladesto belong to a distinct species was their very fine and toughstructure. The accuracy of the determination is now provedby the very different form of its skull from that of any otherknown whale. In the same manner, the Physalus antarcticus,also established on finner-fins or baleen imported from NewZealand, has been proved to be a very distinct species of thatgenus, named Sulphur-bottoms by the whalers.XIII.-On a Collection of Birds from China and Japan. By R. B. SHARPE, F.L.S., Libr. Z.S., &c. With Notes by the Collector, ROBERT H. BERGMAN.I HAVE lately received from my friend Mr. Bergman a smallcollection of birds which he has formed during his leisure timein the course of his cruises between China and Japan. Thisis the first consignment he has transmitted to me; and al-though the birds sent are none of them very rare, I think itadvisable to place on record the very interesting notes whichMr. Bergman has added on the habits of the species noticedby him; and for the trouble taken in this matter he deservesail praise. I shall hope from time to time to contribute furthernotes on Chinese birds as they are sent home to me by thepresent collector. The nomenclature employed is that adoptedby Mr. Swinhoe in his 'Catalogue of the Birds of China'(Proc. Zool. Soc. 1863, p. 259); and I have availed myseIf ofthat gentleman's presence in England to obtain his assistancein the identification of some of the species. 1. Turdus Naumanni.
