says, " hind part of the neck greyish black." The top of the 

 head is described as being spotted with black, indicating imma- 

 turity. A specimen before me has a single white feather on the 

 crown. Such being the case, I cannot avoid concluding that 

 the description of Sterna panayensis fits this well-known species 

 better than its congener, and that the name now under discus- 

 sion had best be left as most modern ornithologists have identi- 

 fied it. 



The species is common about the Cays of the Belize coast. 



75. Haliplana fuliginosa (Gm.) : Salv. Ibis, 1864, p. 385. 

 I only met with a few solitary birds of this species about the 



Cays of the Belize coast. It is said to be much more abundant 

 and to breed in large numbers at Cape Gracias a Dios. 



76. Angus tenuirostris, Temm. : Salv. Ibis, 1864, p. 383 ; 

 Cones, ibid. p. 393. 



Abundant on one small Cay (South-West of All Cay) on the 

 outer margin of Glover's Reef.

 Lagoon of Acapam, on the Pacific coast. 



78. Phalacrocorax floridanus. And. : Salv., Ibis, 1864, 

 p. 374. 



Man-of-War Cay, Belize coast. We possess one other species 

 of Phalacrocorax besides P. mexicanus, which we have not yet 

 been able to identify, as the specimens are immature. 



79. SuLA piscATOR (L.) : Salv. Ibis, 1864, p. 379. 

 Half-moon Cay on the Belize coast, where numbers resort to 



breed. 



80. PoDiCEPS CALiFORNicus, Hcerm. 



Common on the lake of Dueiias, in immature and winter 

 plumage. One specimen in summer dress was shot near Cubulco, 

 in Vera Paz, and brought to us. 



81. PODILYMBUS, sp. 



A second species of this form occurs on the lake of Atitlan. I 

 have not yet determined it.
