ornithological trip in the latter half of 1882, first to Fuji- 

 yama, where a month was passed at Subashiri, 2500 feet 

 above the sea-level, and 326 specimens were obtained, and 

 afterwards to the Nikko mountains and Omachi, in the pro- 

 vince of Shinshiu. Good field-notes are given concerning 

 101 species. Most of them are well-known Japanese birds ; 

 but examples of Accentor erythropygius were obtained on 

 Fuji-yama, and the Ptarmigan [Lagnpus, sp. inc.) of the high 

 peaks of the Tate-yama range Avas heard of, tljough not pro- 

 cured. Mr. Jouy considers Pyrrhula rosacea of Seebohm 

 (Ibis, 1882, p. 371) to be only a highly developed stage of 

 P. orientalis. 



23. Lawrence on a new Hemiprocne. 



[Description of a new Species of Bird of the Family Cypselidae. By 

 George N. Lawrence. Amials New York Acad. Sci. ii. p. 355.] 



The species described is Hemiprocne minor from Bogota. 

 It seems to be like H. zonaris, but smaller. 



24. Lydekker on Slivalik Fossil Birds. 



[Siwalik Birds. By R. Lydekker, B.A., F.G.S., F.Z.S. Mem. Geol. 

 Surv. India, sect. x. vol. iii. pt. 4.] 



In the Siwaliks, Mr. Lydekker tells us, as in most other 

 ossiferous formations, the remains of birds are extremely 

 scarce as compared with those of mammals, and such remains 

 as do occur are mostly in a fragmentary condition. Little 

 has yet been written on the fossil birds of the Siwaliks, and 

 Mr. Lydekker^s present paper is intended to give an account 

 of all the remains which appear capable of identification. 

 Besides some forms, the exact genera of which cannot be 

 determined, Mr. Lydekker describes species of Pelecanus, 

 Phalacrocorox, LeptojMlus, Mergus, Striithio, and Dromceus. 

 Dromceus sivalensis is established on four phalangeal bones, 

 which so clearly resemble those of the living Emu as to 

 leave little doubt that a nearly allied, although possibly not 

 generically identical, bird existed in the Siwaliks.
