4. List of Birds collected on the Blewfields River^ Mosquito 

 Coastj by Mr. Henry Wickham. By P. L. Sclater^ 

 F.R.S., and Osbert Salvin, M.A., F.Z.S. 



Mr. Henry Wickham, who has lately left England to collect ob- 

 jects of natural history in the little explored territory of Mosquitia, 

 has kindly requested his correspondents in this country to submit 

 his bird-skins to our determination. We have had great pleasure 

 in undertaking this task, the more so as we have as yet seen no col- 

 lections from this part of Central America. 



The nearest point of the ornithology of which we have as yet any 

 published account is the vicinity of Greytown, Nicaragua, where 

 Mr. II. E. Holland obtained the small series described by Mr. Livw- 

 rence in the ' Annals of the Lyceum of New York ' in 186.5*. 



Mr. Wickham's ])resent collection embraces thirty-nine species. 

 We have thought it advisable to give a complete list of these 

 (although the greater part are well-known Central American species, 

 and none are new to science) in order to furnish further data for 

 limiting the geographical range of the species. The district is one 

 of considerable interest, as it is somewhere here that the remarkable 

 change must take place for the fauna of Guatemala to pass into that 

 of Costa Rica. We must await further additions before we draw any 

 conclusions from Mr. Wickham's series ; but we may point out as of 

 interest the occurrence in it of several southern forms, such as Cotyle 

 iiropygialis, Dendrornis lucrymosa, Copvrus lenconotus, Myiozetetes 

 yi'anadensis, Myiarchus nigricapillus, Prionorhynchus plutyrhyn- 

 chus, and Porzana alhigularis, not hitherto recorded so far north. 



Mr. Wickham's present collection contains the following species, 

 all collected during his voyage up the Blewfields River : —
