' 53. ToDUS ANGUSTiROSTRis Lafresnaye. 



BarancoM. 



One specimen, Sosua. 



An uncommon species, probably somewhat local in its distribution, 

 although preferring much the same haunts as T. suhulatus. 



In life the bill is dusky above, the lower mandible reddish; iris 

 grey-white; legs dark flesh, feet bluish, soles, yellowish. 



54. Streptoceryle alcyon alcyon (Linne). 



Fairly common along the coast. The natives assert that the species 

 breeds, but this assertion is as yet unsupported by reliable evidence. 



55. Nesoctites micromegas (Sundevall). 

 El Flotero. 



Four specimens, both sexes, Estero Balsa, Sosiia, Los Toritos. 



A fairly common resident. Up to within a few days of my de- 

 parture but three representatives of this species had been observed, 

 all of them taken. For the last two months, however, I had been

 but which seemed impossible to locate. The song, most frequently 

 heard in the forests on the northeastern portion of. the island, but also 

 occurring rather frequently as the season progressed, in the general 

 vicinity of Sosiia, consisted of a series of six whistled notes which 

 may be written graphically as, ^^_/, the last note rising 



abruptly and ending sharply. 



On April 9, however, I heard the song again and finally located the 

 author, after watching to be sure that I had the right bird I shot it. 

 Rather to my surprise it proved to be a female of this species. 



56. Centurus striatus (Miiller). 

 Carpintero. 



Nineteen specimens, both sexes, Monte Cristi, Sosua. Abundant 

 resident. In the desert region of the lower Yaqui Valley it frequents
