^ Oceanodroma monorhis (Swinh.). 



Thalassidroma monorhis, Swinhoe, Ibis, 1867, p. 386 (Amoy) ; Yan 

 Oort, Notes Leyd. Mus., xxxiii, 1911, p. Ill (Semarang, Java). 



There are three known specimens of this rare Petrel from 



Indo-Malayan waters; that from Java recorded above, a female 



obtained at Keppel Harbour, Singapore, by Mr. Koh Ah Wing, now 



in the RaflEies Museum, and a male obtained in the One Fathom 



Bank Lighthouse, oflF the coast of Selangor, in the F. M. S. Museum. 



The species will probably be found on the Siamese coast also. 



Oceanites oceanicus (Kuhl). 



Procellaria oceanica, Kuhl, Beitr., p. 136, pi. x, fig. i. (1820). 

 Oceanites oceanicus, A., p. 490. 



Davison records this species as seen off the Moscows, a group 



of islets north of Tavoy, and we have on several occasions in stormy 



weather seen small black petrels with white rumps, in various parts 



of the Straits Settlements, so the species probably occurs off the 



Siamese coast.
