26 PROCEEDINGS OF THE NATIONAL MUSEUM [vol.82 



EREUNETES PUSILLUS (Linnaeus) 



Semipalmated Sandpiper 



Tringa pusilla Linnaeus, Syst. Nat., ed. 12, vol. 1, 1766, p. 252 (Santo Domingo-^ 

 Hispaniola). 



On a large mud flat near the flying field east of Cap-Haiftien, Haiti, 

 about 100 semipalmated sandpipers were seen on March 26. This 

 species also was common around the shores of the salt lagoons and 

 salt pans on Beata Island, Dominican Republic, May 10 to 15. On 

 the latter date a large flock was evidently in migration as they ap- 

 peared to have just arrived and were decidedly nervous at our 

 approach. Three were taken on May 12. 



EREUNETES MAURI Cabanis 



Western Sandpiper 



Ereunetes mauri Cabanis, Journ. fiir Orn., 1856, p. 149 (Cuba). 



Ordinarily but scant reliance should be placed upon field identifica- 

 tions of the western sandpiper, but occasionally conditions are suffi- 

 ciently favorable to allow satisfactory diagnosis without the necessity 

 for collection. Such an opportunity was presented on March 26, 

 when we identified several of these birds feeding in company with 

 E. pusillus on a mud flat a short distance east of Cap-Haitien, Haiti. 



CROCETHIA alba (Pallas) 



Sanderling 



Trynga alba Pallas, in Vroeg, Cat. Rais., Adumbr., 1764, p. 7 (coast of North 

 Sea). 



The sanderling was noted on but one occasion, when a single bird 

 was observed, May 12, at Beata Island, Dominican Republic, in com- 

 pany with three ruddy turnstones. 



Family RECUR VIROSTRIDAE, Avocets and Stilts 



HIMANTOPUS MEXICANUS (Muller) 



Black-necked Stilt 

 Charadrius mexicanus Muller, Natursystem, Suppl., 1776, p. 117 (Mexico). 



Black-necked stilts were first observed near Cap-Haitien, Haiti, 

 where on March 26 five or six were feeding along the edge of the man- 

 groves on a mud flat. At Terrier Rouge they were heard calling in 

 the moonlit evenings of March 28 and 29. On April 29, at lie a Vache, 

 the characteristic calls of this bird attracted our attention to an interior 

 marsh where half a dozen individuals were seen. A few were observed 

 on May 23, feeding on overflowed land at Source Matelas. 



In the Dominican Republic we noted stilts in the harbor at Bara- 

 hona on May 9, and small numbers were seen daily around the salt 

 lagoons on Beata Island, May 10 to 15.
