108 Mr. 0. Salvin on Mr. Lawrence's 



Birds found in Costa Rica (Ann. Lye. N. H. New York, ix. 

 pp. 141-149 *), and appended thereto some remarks correcting 

 and confirming his previous identification of certain species. A 

 supplementary list is also added of such species as had been 

 subsequently received by the Smithsonian Listitution. 



Mr. Godman^s and my collection has also been enriched by 

 some species not included in Mr. Lawrence's catalogue. It is 

 my intention now to enumerate these, and to add a few rectifi- 

 cations of nomenclature that additional material has enabled me 

 to ascertain. 



(58.) Basileuterus melanotis. 



Two specimens of a Basileuterus, agreeing accurately with 

 Mr. Lawrence's description, have been recently sent us by 

 Arce from Veragua. They are hardly appreciably darker on 

 the upper surface than Bogota and Ecuador specimens attri- 

 buted by Mr. Sclater (Cat. Am. B. p. 34) to B. hivittatus (Lafr. 

 & D'Orb.); in other respects they are quite the same. These 

 skins answer to D'Orbigny's description (Voy. Ois. p. 324), and 

 also to that of Myiodioctes tristriatus, Tsch. (Faun. Per. p. 193). 

 I have not seen Bolivian or Peruvian specimens, but I have little 

 doubt that the same species is found in all the above-mentioned 

 countries. 



(65.) Stelgidopteryx fulvigula. 



Since writing my note on this species (Ibis, 1869, p. 313), we 

 have received a specimen from Carmiol which, upon examina- 

 tion, proved to be the true S. fulvigula, Baird, and shows that 

 the specimen so called which we received from the Smithsonian 

 Institution is not S. fulvigula at all, but S.fulvipennis, Scl., 

 agreeing, as before stated, with Guatemalan examples attri- 

 buted to that species. The Smithsonian specimen (No. 41246) 



* There is nothing on the second portion of this catalogue to show that 

 it was issued some months later than the first portion. What appears to 

 have been the case is that separate copies of the latter were struck oft" and 

 distributed by Mr. Lawrence some time before the issue of the part of 

 the Annals of the New- York Lyceum which contains the paper. What 

 is the true date of this communication ? The first portion bears the date 

 " April 1868" (qu. that of reading ?) ; and in the second, reference is made 

 to the number of ' Exotic Ornithology ' issued in October 1868.
