second voyage, as the species now known as Pterodroma 

 parvirostris (Peale) from Christmas Island of the Fanning 

 group. Mr. W. E. Clyde Todd monographs the South 

 American Crested Quails of the genus Eupsychortyx, and 

 illustrates their distinctive characters by a coloured plate 

 and tlicir distribution by two maps. Dr. J. Dwight, wlio 

 has long been engaged in the study of moult and change of 

 plumage, has an interesting and instructive article on the 

 Gulls. He believes that the smaller gulls attain their adult 

 dress in the second year, while in the largest forms this 

 process is prolonged until the fourth year. He also points 

 out that younger birds can be detected by the more pointed 

 shape of the primaries and by the more rounded ends of the 

 tail-feathers. The successive plumages of Larus philadelplda 

 and L. argentatus are described at length and illustrated on 

 five carefully drawn plates. The question of tlie distinctive 

 characters of the Common and Barrow's Golden-eye are 

 discussed at length by Mr. Allan Brooks, as well as some 

 other points in regard to the ducks of British Columbia ; 

 his remarks are illustrated by some fascinating drawings 

 from his own brush. 



The Killdeer Plover {Oxyechus vociferus), a common 

 North-American bird, has long been known to range to 

 South America, but was supposed to go there oidy during 

 the winter months as a migrant. Recently Mr. Harry 

 WatkinSj who has been collecting for the American Museum 

 in New York, has sent to Mr. Chapman fourteen examples 

 of the Killdeer which he found breeding on the coast of 

 Peru. The bird turns out to be separable from the North- 

 American one, and is named Oxyechus vociferus peruvianus 

 by Mr. Chapman. 



Another new bird described is a duck of the Mallard 

 group found in New Mexico and named by Mr. W. Huber 

 Anas 7iovimexicana. 



Of the faunal papers, Mr. S. Cobb writes on the birds of 

 the Catskill Mountains in New York, Mr. L. Griscom on
