Carriker: List of the Birds of Costa Rica. 359 



on the Gulf of Nicoya (probably at Tempate and Bebedero), after 

 which he crossed over to the Caribbean slope, collecting at Tucurriqui 

 and on the Volcano de Irazu. Most of the new species came from 

 Tucurriqui. In the article describing these new species Mr. Salvin 

 says : "I am now acquainted with about 304 species (mostly Passeres) 

 from this country, no less than 65 per cent, of which have been de- 

 scribed by various authors as new, and which have not as yet been 

 found beyond the limits of Costa Rica or the immediate adjoining 

 province of Veragua. ' ' 



During 1863-4 Capt. J. M. Dow (captain of one of the Pacific 

 Mail boats) collected a few birds at Puntarenas while the steamer was 

 there at different times, and some of these skins found their way to 

 the Smithsonian Institution, while most of them went to Mr. Salvin. 

 It was from these specimens (as well as others from Realejo, 

 Nicaragua) that Vireo pallens and Ela'inea (Sublegatus) arenarum 

 were described by Salvin (P. Z. S., 1863, p. 186). 



We are indebted to P. L. Sclater for two additional species in 1865, 

 viz.: Leucopternis princeps (P. Z. S., p. 429) and Calliste (Tangara) 

 dowii {Ibis, Vol. VI, 371). 



Previous to 1868 (date uncertain) Prof. S. F. Baird described 

 several species in his Review of American Birds, of which we have as 

 valid species the following : Setophaga (Myioborus) aurantiaca, S. 

 {M.) torquata, Basileuterus melanogenys, and Vireo carmioli. 



Between 1865-8 there appeared in the Proc. Acad. Nat. Sci. of 

 Philadelphia, several short papers by John Cassin, relating more or less 

 to Costa Rican birds. * In 1865, p. 91, was described Chrysomitris 

 bryanti {Spinus xanthogaster bryanti) ; page 169, a paper entitled, 

 "On Some Conirostral Birds from Costa Rica," contained twenty- 

 three species, of which three were new, Arremon rufodorsalis 

 {Arremon aurantiirostris rufodorsalis'), Buarremon (lysurus) cras- 

 sirostris, and Euphonia annece ; in 1867, p. 51, Icterus salvini 

 (I. me so me las salvini) appeared. 



In 1864 Mr. George Newbold Lawrence began writing on Costa 

 Rican ornithology from material in the Smithsonian, collected by the 

 Carmiofs, Frantzius, Jose Zeledon, Juan Cooper, Manuel L. Calleja, 

 and A. R. Endres. His list of 1868 contains all the above names as 

 collectors of material used, and between 1864 and 1868 (when his 

 list appeared) eight papers had been written describing new species of 

 birds from Costa Rica as follows: Tachyphonus {Pselliophorus)
