47. Lawrence on new Trochilidse and Tetraonidae. 



[Descriptions of new Species of Birds of the Families Trochilidae and 

 Tetraonidfe. 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 0. cristatus. Of the so-called O. 

 emigrans, 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 0. emigrans ? 



The Quail described is called Cyrtonyx sumichrasti, 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. sallai. 



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
