but they are frequently found in moist pastures and small pond-holes, 

 ^'ery few birds in the white plujnage were noted. 



10. BuTORiDES VIRESCENS viRESCENs (Linne). 



Martinete. 



A male Sosua. 



Accidental visitor. The specimen, taken March 29, agrees per- 

 fectly in color and size with representatives from the United States; 

 the sides of the neck being more purplish than in B. v. maculatus, 

 while all its measurements are larger than typical B. v. maculatus. 

 Wing 177, tail 70.5, exposed culmen 60, tarsus 52, middle toe 44 mm. 



While I have referred this specimen to the continental form it is 

 perfectly possible that its larger size may be due to individual varia- 

 tion in B. V. maculatus. However there is no particular reason why 

 B. V. virescens should not occasionally occur in the other of the Greater 

 Antilles, as it has been taken in Porto Rico (Oberholser, Proc. U. S. 

 N. M., 42, p. 539). 



11. BuTORiDES VIRESCENS MACULATUS (Boddaert). 

 Martinete. 



Eight specimens, both sexes, adults, and immature, Monte Cristi, 

 Sosua. 



The Antillean Green Heron is locally common at favorable locali- 

 ties on the north coast of the island. They were rather numerous 

 along the course of the Yaqui River near Monte Cristi. At Sosua 

 they frequented ditches and mud-holes, seeming to prefer these 

 locations to the larger bodies of water. A small tree overhanging a 

 sluggish stream contained the remains of two of their characteristic 

 nests from which the young had already left by the last week in 

 March. 



12. Nyctocorax nyctocorax naevius (Boddaert). 

 An adult and an immature seen near the Sosua River, April 10. 



13. Ajaia ajaja (Linne). 



Spoonbills occur sparingly near Monte Cristi. Mr. Curt Peters 

 showed me a skull he obtained from the marshes at the mouth of the 

 Yaqui River.
