different to Riparia chinensis, larger and, in the case o£ one 

 flock, with paler rumps. This is the more probable in that 

 birds found breeding at Jhelum (Ibis, 1916, p. 69) were 

 referred to Riparia riparia and described as a new race of 

 that form, R. r. indica Ticehurst. I have carefully com- 

 pared these Jhang birds with those from Jhelum, and there 

 is no doubt of their distinctness. On the other hand, 

 breeding-birds obtained in January and February at C'amp- 

 bellpore and Attock by ftlr. A. E. Jones are the same as the 

 Jhelum birds. It is clear that a lot of work remains to be 

 done as regards the Sand-Martins of India. 



Riparia rupestris (Sco[)oli). 



A winter straggler only ; one was seen at Jhang on 

 8 March, 1918, one or two about the low hills at Yakkuwala 

 on 23 February, 1919, and one at Jhang on 2 January, 

 1920. 



[Delichon urbica (L.). 



Two ^lartins seen on 13 October, 1918, were almost 

 certainly of this species.]

XVII. — Remarks on the Japanese Petrels of the Genus 

 Oceanodroma. By Nagamichi Kuroda, Rigakushi, 

 M.O.S.J., F.M.B.O.U. 



Viscount Y. Matsudaira, M.O.S.J., has recently collected 

 a series of Petrels ofE the coast of Sagami Bay, Hondo, 

 Japan, and has sent them to me for examination. They are 

 preserved in his collection. I examined them very carefully, 

 and came to the conclusion that the series contains two 

 species. They are as follows : — 



Oceanodroma melania (Bonaparte). 



Oceanodroma markhami owstoni (Mathews k Iredalc).
