THE BIEDS OF HAITI AND THE DOMINICAN REPUBLIC 251 



dem Boden befinden. Der Ruf ist ein schauerlich klingendes weithin 

 horbares Pitangua, gegen das Ende stark anschwellend." As Antro- 

 stomus carolinensis, the chuck-will's-widow, is known only as a mi- 

 grant these observations may refer to the native species. 



This bird in size and form is similar to Antrostomus cubanensis 

 cubanensis Lawrence of Cuba from which it differs in having the 

 light tips of the outer rectrices and the under tail coverts cinnamon- 

 buff, immaculate except for the longer central feathers which have 

 dark bars on the outer webs, and with the light mottlings on the 

 inner webs of the primaries less extensive, the feathers being im- 

 maculate on the inner web for the distal fourth. The Cuban form 

 has the entire under tail coverts heavily barred with the inner webs 

 of the primaries displaying extensive mottled bars that extend to 

 distal end of the feathers. 



Though Abbott noted developing eggs as large as number two 

 shot in his specimen for some reason he marked it " $ ? ". After 

 comparison with Cuban birds it appears to be a female, as the female 

 of that form differs from the male, in addition to the narrower light 

 band on the tip of the tail, in having distinct paler markings on the 

 inner webs of the outer rectrices, producing a series of bars. This 

 area in the male is immaculate. As the bird from Mao has the 

 mottled bars on the inner webs of the rectrices it appears certainly 

 to be a female. It has the following measurements (in millimeters) ; 

 wing 170.5, tail 128.3, culmen from base 16.3, tarsus 17.9. The 

 dimensions are closely similar to those of A. c. cubanensis. 



The present bird in form is like the chuck-will's-widow but is 

 smaller, and grayer, less buffy, in color. In the hand it may be told 

 by shorter wing, which measures about 170 mm. (instead of the 

 200 mm. or more of the chuck-will's-widow) and by the smooth 

 bases of the rictal bristles which lack lateral filaments. (PI. 20.)

Resident; local. 



The present species, peculiar to the island, was first taken by R. H. 

 Beck, who collected an adult female near Tiibano, in the Province 

 of Azua, February 10, 1917. Hartert informs us that Kaempfer 

 secured three specimens for the Tring Museum, near Tiibano on
