Zeledon's Catalogue of the Birds of Costa Rica.* — ThisWs simplv an 

 enumeration of the birds of Costa Rica, without notes. The catalogue 

 numbers 692 species, about eight to nine tenths of them being indicated as 

 represented in the National Museum by Costa Rican specimens! The iden- 

 tification of the species is therefore doubtless beyond question. This list 

 is intended as preliminary to a work of a more extended character to con- 

 tain descriptions of the genera and species, with notes on their habits and 

 geographical distribution, which the author has in contemplation, and for 

 which his long residence in the country, and his unrivalled experience 

 with the birds of Costa Rica eminently fit him to prepare. — J. A. A. 



Ridgway on New American Birds. — Mr. Ridgway has separated the 

 Boat-billed Heron of Central America from that of Guiana and Brazil, un- 

 der the name Cancroma zelcdo>ti.\ Twelve examples from southern ami 

 western Mexico, Guatemala. Nicaragua, Costa Rica, and Veragua are 

 found to differ constantly from two South American specimens (British 

 Guiana and mouth of the Amazon) in having the upper parts much deeper 

 pearl-gray, the neck and breast deep buff instead of white, and the crest 

 less developed. 



The same author has also described a new Hawk from Cozumel, under 

 the name Rupornis gracilis. % It is compared with R. ruficauda grisei- 

 c.aiida of Mexico, from which it differs in being decidedly smaller, with 

 the thighs and under wing-coverts nearly immaculate instead of barred 

 and spotted. 



A re-examination of some specimens of Peuccea collected by Dr. J. C. 

 Merrill, and identified by Mr. Ridgway as Peuccea arizonce (Proc. U. S. 

 Nat. Mus., I, p. 127), in the light of additional material, shows that the 

 specimens represent Coturniculus mexicana of Lawrence, described from 

 Mexican specimens in 1S67. and subsequently referred by Mr. Ridgway 

 (Hist. X. Am. Birds, II, p. 38, footnote) to P. botterii. A second exami- 

 nation of the Texas specimens, in comparison with the Mexican examples. 

 results in the addition of a new bird to the fauna of the United States, 

 which Mr. Ridgway calls Peuccea mexicana (Lawr.). 



In a paper on the Golden Warblers§ Mr. Ridgway describes a new sub- 

 species from Western Mexico and Cape St. Lucas as Doidrocca bryanti 

 castaneiceps. D. bryanti is now separated specifically from D. vieilloti, 

 to which it was originally referred as a subspecies, and its habitat is 

 restricted to the "Atlantic coast, Belize to Northern Yucatan (Meridai."
