List of Costa-Rica Birds. 319 



Accipiter pileatus to A. bicolor, Vieill. 

 Geotrygon caruleiceps to G. chiriquensis, Scl. 

 Penelope purpurascens to P. jacuaca, Spix ? 

 Ortalida poliocephala to O. cinereiceps, G. R. Gray. 



I now add the names of a few species to the list of Costa- 

 Rica biids which do not as yet seem to have come under Mr. 

 Lawrence's notice : — 



1. Cacicus microrhynchus , Scl. & Salv. Peje (/. Carmiol). 



2. Dendromanes atrirostris (Lafr.), Angostura (/, Carmiol). 



3. Dendromanes homnchrous, Scl. Costa Rica (/. Carrniol). 



4. Xenops heterurus, Cab. Costa Rica (/. Cai'miol). 



5. Rhamphocanus rufiventris, Bp. Bebedero [Arce). 



6. Leptopogon pileatus, Cab. Valza (/. Carmiol). 



7. Serpophaga cinerea. Costa Rica (Endres). 



8. Lophornis helence, Delatt. Tucurriqui [Arce) 



9. Petasophora delphince. Costa Rica (/. Carmiol). 



10. Clais guimeti. Costa Rica [Endres). 



11. Conurus lineolatus. Angostura [J. Carmiol). 



12. Hypotriorchis rufigularis. Costa Rica (/. Carmiol). 



13. Cathartes atratus. Costa Rica (/. Carmiol). 



It will be seen that I leave Mr. Lawrence's list as regards 

 numbers almost where I found it, by removing fourteen species, 

 and replacing them by thirteen others. There are then 473 

 species of " Land-birds " known to inhabit Costa Rica ; and if 

 the remainder equal in number the A\aders and others of Gua- 

 temala, the total number of birds constituting the avifauna of 

 Costa Rica will reach altogether to 574 or thereabouts. If to 

 these be added the species of the adjoining countries of Veragua 

 and Panama, so as to include the whole of the birds of the 

 southern section of the Central- American fauna, we have a total 

 of 630 species. 



This brief summary will give some idea of the marvellous 

 richness of the ornithic productions of this interesting and 

 favoured country.
