Actiturus bartramius Lawrence, Ann. Lye. N. Y., IX, 1868, 142 (C. R. [| 

 Carmiol]). 



Am. Mus. Nat. History: San Jose, Sept. 18, 1889 (Underwood). 

 Bangs Collection : San Jose, Sept. 15 (Underwood). 

 C. H. Lankester Collection : San Jose, Sept. 15, 1907. 

 Carnegie Museum : Guacimo, Oct. 13, 1903 (Carriker). One skin. 

 This species is a common winter visitant on the " sabanas " about 

 San Jose, but apparently does not remain there all winter. I found it 

 common there in October, 1907. The single specimen secured at 

 Guacimo was shot in a newly ploughed field and no more were seen. 

 I suspect that it does not descend much into the low country, but 

 remains on the plateau. 



74. Ereunetes pusillus (Linnseus). 



Trin^a pusilla Linnaeus, Syst. Nat., I, 1766, 252. 



Ereunetes pusillus Baird, Brewer, and Ridgway, Water-Birds N. Amer., 1, 1884, 

 205. — Sharpe, Cat. Birds Brit. Mus., XXIV, 1896, 514. — Sai.vin and 

 Godman, Biol. Centr.-Am., Aves, III, 1903, 382 (Guatemala and Panama). — 

 Bangs, Proc. Biol. Soc. Wash., XIX, 102 (San Jose, Sept. 15, 1898 [Under- 

 wood]). 



Carnegie Museum: Coronado de Terraba, July 3, 1907 — S" & 9 



(Carriker). Two skins. 



Evidently only a rare straggler in Costa Rica. I can find no 

 records for its occurrence there besides the single specimen recorded 

 by Mr. Bangs and the two secured by myself. These two were 

 secured on a mud-flat along a salt-lagoon, or rather on one of the 

 branches of the delta of the Rio Grande, and were two of a flock of 

 about a dozen birds. It is a remarkable occurrence to get this bird 

 in Costa Rica at that late date, but most likely, having missed the 

 regular return flight, they would have spent the summer there. 



75. Ereunetes mauri Cabanis. 



Ereunetes mauri Cabanis, Jour, fiir Orn., 1856, 419. — Auk, XXV, 1908, Four- 

 teenth Supp. A. O. U. Check List, 367. 



Ereunetes occidentalis Bangs, Auk, XXIV, 1907, 291 (Barranca de Puntarenas, 

 August [Underwood]). 



Two specimens were taken by Underwood at Barranca de Pun- 

 tarenas on August 12 and 20, 1906, while another was secured at 

 La Herradura de Puntarenas on August 12. These specimens are 

 apparently the only records for the occurrence of this species in 

 Costa Rica.
