Canon Tristvam on San Domingo Birds. 167 



(4) Molothrus murinus, Pelz. Orn. Bras., from Rio Janeiro 

 (Natt.), is based upon two female specimens. 



(5) Agelaius pustulatus, S\v. An. in Men. p. 303, from 

 Brazil, if correctly described, is different from any thing that 

 I have seen, 



(6) Idiopsar brachyurus, Cassin, Pr. Ac. Sc. Phil. 1866, 

 p. 414, from Bolivia, remarkable for its short tail and plum- 

 beous plumage, is unknown to me. Is it an Iderine ? (Mus. 

 Smiths. Inst.)^ 



(7) Quiscalus mexicanus, Cassin, op. cit. p. 408. A uni- 

 formly coloured species belonging to the group Haloquiscalus, 

 which is likewise unknown to me. 



XV. — On a Collection of San Dommgo Birds. 

 By H. B. Tristram, D.D., F.R.S. 



A SMALL collection of birds lately made by Mr. C. McGrigor 

 in the island of San Domingo has been placed in my hands 

 for determination; and though it contains nothing new, yet 

 so few collections reach us from that island, the natural 

 history of which was perhaps better known a century ago 

 than to-day, that an account of it may be of interest to some 

 readers of ' The Ibis.' Witb the exception of some of the 

 cosmopolitan Waders, all the species in the series have been 

 already recorded from this locality ; but some of them are 

 rare, notably a large Picumnus, which has recently been 

 described and figured by Mr. C. B. Cory under the name of 

 Picumnus lawrencii (Bull. Nuttall Orn. Club, vol. vi. 1881, 

 p. 129). Both male and female are contained in this collec- 

 tion, and I am satisfied that Mr. Cory^s name must sink into 

 a synonym of SundevalFs P. micromegas (Conspect. Av. Picin. 

 p. 95). Sundevall described this species from a specimen in 

 the Museum of Stockliolm, which was hitherto, so far as I 

 am aware, unique in European collections. But Mr. Coiy 



* p.S. — The authorities of the U. S. Nat. Museum have most kindly 

 sent me this type for comparison. I propose to give an account of it in 

 the next Number of this Journal.
