was shot ill the Bay of Fonseca by Capt. J. M. Dow, who kindly 

 presented it to me. 



69. Thalasseus regius, Gambel : Baird, Birds N. A. p. 859 ; 

 Coues, Ibis, 1864, p. 388 ; Salv. ibid. p. 385, et 1865, p. 190. 



Also abundant on both coasts. 



70. Gelochelidon anglica (Mont.) : Coues, Ibis, 1864, 

 p. 389, et 1865, p. 190. 



Common at Chiapara. 



71. Sterna paradisea, Briinn. : Coues, Ibis, 1864, p. 389; 

 Salv. ibid. p. 387. 



I observed only three or four of this species on Grassy Cay, 

 Turneff. They were, I believe, preparing to breed on that 

 island, which was also tenanted by great numbers of S. antil- 

 lai'um. 



72. Sterna forsteri, Nutt. : Coues, Ibis, 1864, p. 390. 

 The only Tern I ever saw on the lake of Dueiias.

 & 387 ; Coues, Ibis, 1864, p. 390. 



Mr. E. Bartlett has lately sent home a specimen of a Sterna, 

 which I have no doubt is the S. super ciliaris, Vieill. The dif- 

 ferences between this bird and S. antillarum are ably stated by 

 Dr. Coues as above quoted, and apply equally to the Bogotan 

 specimen he had before him and ^to Mr. Bartlett^s from the 

 Upper Amazons.

I cannot agree with Mr. Lawrence in justifying Dr. Coues's re- 

 description of this bird under a new specific name. Gmelin's 

 remark, '' cervix ex cinerascenti nigra,'' I think at once shows 

 that the bird he was describing certainly was not H. fuliginosa, 

 with which both he and Latham were well acquainted. This cha- 

 racter is, on the contrary, applicable to the present species, and 

 is also noticed by Latham (Gen. Hist. vol. x. p. 119), where he
