" I saw this species, which in habits much resembles the last- 

 named, at Ambohitroni, and also at Nossi-be, where I ob- 

 tained a specimen." — S. R.

" When crossing the Mangourou, near Ambohitroni, on the 

 24th of October, a small Grebe was seen. The next day, on a 

 little swamp in the great plain, I shot a male. This plain, I 

 may mention, is a delightful spot for an ornithologist ; and I am 

 sure we should have been well repaid, had we been able to stay 

 there a week. The iris of this bird is red." — E. N. 



" I saw what I believe to have been a specimen of this species 

 at Nossi-be."— S. R.

Several of these small Petrels followed us on our voyage from 

 Mauritius to Tamatave ; and the day before we made the land of 

 Madagascar, one was caught by a piece of thread, which had 

 been thrown over the taffrail to trail in the sea. It was a male.

A Gull was observed by us in the roadstead of Tamatave on 

 our arrival there in September.

" On our return journey, on the 24th of October, I saw two 

 Cormorants, probably of this species — one on the Antataby and 

 one on the Mangourou." — E. N. 



"I saw a Cormorant, at Nossi-be, which appeared to me very 

 similar to the bird found on the marshes near Calcutta." — S. R.
