plored, namely, the islands of Dominica* and Saint Vincent.^ Introduc- 

 tory to these lists are several pages descriptive of the islands in question, 

 and of his experiences there, by Mr. Ober, and copious notes by the same 

 gentleman relating to the habits of the various species observed, and giving 

 measurements, color of eyes, etc., from the fresh specimens. The Domin- 

 ican list numbers fifty-six species, of which rather more than one third 

 are North American, but the greater part of these are wading and swim- 

 ming biids. Six species are mentioned that are not scientifically deter- 

 mined. To the insular form of the Barn Owl (Strix Jlammea), occurring 

 here, Mr. Lawrence gives the varietal name nic/rescens. The Saint Vin- 

 cent list numbers fifty-nine species (including three undetermined), one 

 half of which are common also to the Island of Dominica, and nearly one 

 half to North America. About one fifth of the whole number are semi- 

 cosmopolitan GrallcB. The characteristic species, as would be expected, 

 belong to genera almost wholly tropical in distribution. Mr. Ober notes 

 especially the paucity of species as well as of individuals, and the total 

 absence of Woodpeckers, although the islands are well forested. 



Mr. Ober also made collections at the islands of Grenada, Antigua, and 

 Barbuda. Those obtained at the two islands last-named he left to be 

 forwarded at the earliest opportunity, but they appear to have not yet 

 reached this country. Although Mr. Ober's work was several times inter- 

 rupted by severe illness, the results attained are of the highest importance, 

 and relate not only to ornithology but to other departments of science. —
