mottled with dusky, and the brown spot behind the ear-coverts 

 is very distinct. Wing 13.

 Very common.

 Very common. 



989. Thalasseus . 



At Balacherry, on the Gulf of Kuchh, I frequently noticed 

 a sea-Tern, which I believe to have been Th. bengalensis, 

 but which may have been the larger species. I never ob- 

 tained a specimen. 



1004. Pelecanus 



Pelicans, both grey and white, are not uncommon both on 

 the coast and on the large inland lakes, but they take good 

 care to keep out of shot.

 Common on the Null.

 Common. 



XLVI. — Letters, Announcements, fyc. 



The following letters, addressed " To the Editor of ' The 

 Ibis/ " have been received : — 



Sir, — In the ' Proceedings ' of the Zoological Society for 

 1865, p. 823, I described the Harrier of New Caledonia under 

 the name of " Circus wolfi." Since that time some eminent 

 ornithologists have expressed the opinion that this Harrier is 

 not really distinct from C. gouldi of Australia and New Zea- 

 land ; I am therefore desirous of calling attention to a recent 

 corroboration of my view as to the specific distinctness of 

 these two Harriers, which will be found in page 16 of the in- 

 troduction to Mr. Bullcr's valuable ' History of the Birds of 

 New Zealand/
