47. Lawrence on new Trochilidse and Tetraonidse. 
- f [Descriptions of new Species of Birds of the Families Trochilidse and 
Tetraonidse. Ann. N.Y. Ac. Sc. i. p. 50.] 
The Humming-birds here described are Sporadinus bracei, 
from New Providence, Bahamas, apparently a close ally of 
S. ricordi of Cuba; and Orthorhynchus emigrans, said to be 
from Venezuela, and allied to O. cristatus. Of the so-called O. 
emigranSj through Mr. Lawrence^s kindness, we possess a spe¬ 
cimen, and cannot forbear to say that we altogether fail to see 
how it differs from the ordinary O. cristatus. Then, too, we 
have been brought up to believe that Orthorhynchus is a purely 
Antillean genus. Is Mr. Lawrence sure that there is no 
mistake in the origin assigned to his O. emigrans ? 
The Quail described is called Cyrtonyoo sumichrastl, the 
characters being drawn up by Prof. Sumichrast, in anticipa¬ 
tion of the specimen being transmitted to Washington. It is 
evident from the description that the species must be closely 
allied to C, salleei. 
48. Lawrence on new West-Indian Birds, 
[Descriptions of Seven new Species of Birds from the Island of St. 
Vincent, West Indies (Ann. N.Y. Ac. Sc. i. p. 147) ; and Descriptions of 
supposed new Species of Birds from the Islands of Grenada and Dominica, 
West Indies (op. cit. p. 160).] 
Mr. Ober, whose doings in Dominica we have already 
recorded (antea^ p. 195), has since been attacking St. Vincent 
and Grenada. In the former island he succeeded in securing 
specimens of thirty-five species of birds, and observed or 
obtained tidings of twenty-four others. In the latter he 
obtained specimens of twenty-eight species. Mr. Lawrence, 
to whom the collections were submitted, has in the first 
paper described seven species as new, all more or less inter¬ 
esting, and some even remarkable species. There is amongst 
them a true Turdus, called T. nigrirostris. A Myiadestes, of
