104 Recently published Ornithological Works. [Ibis, 



Magellanic Goose, introduced recently from the Falkland 

 Islands, where it is in some danger of extermination. With 

 regard to the Teal, Mr. Murphy is satisfied that its relation- 

 ships are not with the other South-American species of the 

 same genus, such as Nettion fiavirostre, N. oxypterum, and 

 N. andinu7n, but with the Duck known as Dafila spinicauda, 

 widely distributed in South America, which it seems to 

 resemble closely in markings and proportions, though it has 

 sixteen rectrices, whereas the Pintail has only fourteen. 

 But then, again, Dafila acuta, the type of the genus, has 

 sixteen, so that the number of the rectrices of Ducks do not 

 seem to count for much. 



Mr. Murphy found nests and eggs of Nettion georcfianum, 

 and gives us some interesting field- notes, as well as a photo- 

 graph of the birds at the nest. They only lay five eggs, a 

 tribute to the severity of the struggle for existence in so 

 remote and southerly a spot. 



Noble on the Birds of Guadeloupe. 



[The resident Birds of Guadeloupe. By G. K. Noble. Bull. Mus. 

 Cornp. Zool. Cambridge, Mass. Ix. 1916, pp. 359-396.] 



Mr. Noble was fortunate enough to be able to pay a 

 three months' visit, in the summer of 1914, to the French 

 West India Island of Guadeloupe, in the interest of the 

 Museum of Comparative Zoology, during which time he 

 mainly occupied himself with the resident land-birds, and 

 he was fortunate enough to come across all the existing 

 resident species. The birds dealt with number 46 in all, 

 and in addition to the vernacular names and field-notes, 

 there are valuable remarks on the taxonomy and relation- 

 ships of many of the species. 



In some respects Mr. Noble is conservative in his views. 

 He believes that the numerous Antillean races of the Green 

 Heron {Butorides virescens), recently described by Ober- 

 holser, cannot be maintained, but that all the Green Herons 

 from Cuba to Grenada must be referred to one subspecies 

 (B. V. maculatus). He also finds that Cichlherminia coryi 

 Ridgway, is the adult of C herminieri (Lafr.), the type of
