THE BIRDS OF HAITI AND THE DOMINICAN REPUBLIC 245 



Following are measurements in millimeters of the two specimens 

 seen: 



Acad. Nat. Sci. Phila. No. 82,270, male, wing 294, tail 130, culmen 

 and cere 30.0, tarsus 52.5. 



U.S.N.M. No. 279,303, female, wing 297, tail 132, culmen and cere 

 28.0, tarsus 57.2. 



On comparison it develops that Asio domingensis is so related to 

 A. portoricensis Ridgway, of the adjacent island of Porto Rico that 

 the two should be treated as geographic races. The Porto Rican bird 

 is distinguished by slightly smaller size, the wing in four example^ 

 ranging from 274 to 281 mm. (average 277 mm.), more rounded tail, 

 darker forehead and less heavily marked chest. In general color, 

 except as noted, the two forms are closely similar, birds in first 

 fall plumage being darker buff than those that are older. The Porto 

 Rican short-eared owl will be known as Asio domingensis portori- 

 cen-sis Ridgway. 



The Hispaniolan short-eared owl is dark brown above with the 

 feathers edged prominently with cinnamon buff, with bars of the 

 latter color on wings and tail. There is a dark ring around the eye 

 beyond which the facial disk is cinnamon buff and white. The bird is 

 cinnamon buff below with the abdomen immaculate, the sides and 

 flanks very lightly streaked and the breast very heavily marked with 

 dusky. The bird is easily distinguished from the barn owl by the 

 difference in color of the facial disk and from the eared owl by its 

 smooth head and paler color.

Little is at present known of this owl, first described from an 

 adult male secured by Dr. TV. L. Abbott near Constanza, D. R., at 

 an elevation of about 1200 meters, on September 23, 1916. 

 (PI. 19.) Kaempfer collected a second bird from the swampy 

 forests at the mouth of the Rio Yiina, which Hartert says is an 

 adult female taken November 18, 1922. Abbott informs us that this 

 latter bird was secured alive from a native. According to infor-
