30. Calidris leucophea (Pallas). 



Rare migrant. A Sanderling was seen on the open sand-beach a 

 few miles east of Gaspar Hernandez on March 4. 



The species is not included in the lists of Bryant, Cory, and Verrill. 



31. AcTiTis macularia (Linne). 



Common winter resident. The Spotted Sandpiper was found at 

 Monte Cristi, Sosua, and along the sand-beaches from Cabarete to 

 San Juan. They often occur where the mangroves adjoin the beach 

 and seem equally at home running up and down the sand or hopping 

 from root to root in the swamps. They were still present on April 1 1 , 

 the day of my departure. 



32. Squatarola squatarola cynosurae Thayer & Bangs. 



Rather uncommon winter resident. On February 18, a flock of 

 about 20 birds was observed at Monte Cristi on a flat left bare by the 

 clearing off of mangroves. Two others, both in immature plumage 

 were seen on the hard sand-beach some miles west of the mouth of the 

 Rio San Juan on March 4. 



33. OxYECHUs vociFERUs RUBiDus Riley. 



Six, both sexes, Jaibon, Gaspar Hernandez. 



All of these specimens belong to the small resident form of the Antil- 

 lean Killdeer. The ovaries of a female taken at Jaibon as early a^ 

 February 14, showed some slight signs of activity. Two pair were 

 killed at Gaspar Hernandez, March 14, that certainly acted as though 

 mated; the sexual organs of both males and females were somewhat 

 enlarged. 



Killdeer were fairly common at Monte Cristi during the second and 

 third weeks in February, though none were taken. It is possible 

 that some of these might have been migrants from North America, 

 as Dr. Barbour tells me that 0. v. wciferus winters commonly in 

 Cuba. 



34. Charadrius semipalmatus (Bonaparte). 



A rather uncommon migrant. A small flock was seen near Monte 

 Cristi, February 18, but none of the birds were secured.
