THE BIRDS OF HAITI AND THE DOMINICAN REPUBLIC 353 



the breeding season, as many as five nests being found during my two 

 weeks' stay on the island during that month. These were placed 

 from about one to three feet above the ground, and contained one 

 fresh egg, two fresh eggs, three heavily incubated eggs, and three 

 young nearly ready to leave the nest, while one nest was empty, the 

 young having but recently flown. A single egg secured March 18th 

 measures 21.6 by 14.5 mm." A nest that he collected is a cuplike 

 structure suspended, as usual in vireos, by the margin from a fork 

 at the end of a limb. It is made of strips of bark with a lining and 

 filling of leaves and other soft materials, with a very deep cup. The 

 occurrence of this vireo on Tortue is of considerable interest since 

 the species crassirostris, with four other geographic races, range 

 through the Bahama and Cayman Islands to Old Providence in the 

 Caribbean Sea. As Tortue is only fifty miles from Great Inagua 

 the separation here is not great, it being more remarkable that the 

 vireo has not crossed from Tortue to the coast of Haiti less than 

 five miles away. 



Vireo crassirostris tortugae differs from Vireo c. crassirostris in 

 being tinged or washed with buff instead of yellow below, and in 

 having the upper surface buffy brown rather than grayish. It does 

 not require comparison with the other forms of crassirostris 

 (flavescens, alleni and approximates) as these are brighter colored, 

 being much more yellow. V. c. tortugae is subject to considerable 

 plumage wear as the summer season advances, then appearing grayer 

 than in fresh dress. Even worn specimens are browner, however, 

 than crassirostris. The twenty-one specimens available were taken 

 from January 30 to February 8, April 7 and 8, and June 29, 1917. 

 Measurements from this entire series show no appreciable difference 

 from crassirostris, the smaller size alleged in the original description 

 disappearing when a larger series is measured. Dimensions of 

 tortugae (in millimeters) are as follows: 



Males, 17 specimens, wing 59.3-63.4 (61.5), tail 45.7-51.5 (48.9), 

 culmen from base 12.2-13.8 (12.9), tarsus 18.3-20.8 (19.8). 



Females, 4 specimens, wing 57.0-63.3 (59.5), tail 44.3-46.8 (45.9), 

 culmen from base 12.4-13.6 (12.9), tarsus 19.5-20.3 (19.9). 



Type, male, wing 62.7, tail 50.7, culmen from base 13.3, tarsus 19.8. 



There is apparently some difference in eye color, due possibly to 

 age as Abbott has marked this on different specimens as pale yellow- 

 ish, grayish white, gray and dark gray. He indicates the bill as 

 lead color, blackish above, and the tarsi as leaden. 



This vireo is from 129 to 136 mm. long, dull buffy brown above, 

 and whitish washed with buff (more heavily on the chest) below. 

 A yellowish white line extends from above the eye to the lores, and 

 there are two white wine; bars.
