Nineteen females, wing 126.7-144.6 (136.6), tail 182.0-227.0 (210.0), 

 culmen from base 46.4-54.3 (49.3), tarsus 33.9-39.3 (36.7) mm. 



The lizard-cuckoo ranges from 405 to 450 mm. in length, more 

 than one half of this being taken by the greatly elongated tail. The 

 bird is slender in form, with a long bill that in life appears nearly 

 straight. (PI. 17.) The upper surface is dark grayish brown, the 

 breast light gray, the throat and abdomen cinnamon, and the under 

 surface of the tail black with the feathers broadly tipped with white.

Gonave Island; resident. 



The present form, named in honor of James L. Peters of the 

 Museum of Comparative Zoology, is restricted to Gonave Island 

 where W. L. Abbott collected the type, a male, near La Mahotiere on 

 the south coast, February 20, 1918, and others on February 19, 20, 21, 

 22, and 23. On a subsequent visit he secured three additional males 

 at Anse a Galets March 6 and 8, 1920. He reports that the bird is 

 common in the dense scrubs and that its habits are similar to those of 

 the mainland form except that it seems shyer. One that he examined 

 had eaten a lizard. He describes the tarsus as lead-colored and the 

 iris as reddish brown. Bond says that this race does not differ in 

 notes and habits from the bird of the main island. Danforth reports 

 that it is not as common as typical longirostris. In the stomach of 

 one he found a lizard (Anolis), two sphingid caterpillars, three 

 noctuid caterpillars, a chrysalid, and the wings of a damsel fly. 



This race differs from Saurothera I. longirostris in the restriction 

 or absence of the buffy throat patch, paler abdomen and undertail 

 coverts, and paler dorsal surface. Three of our skins have no buff 

 on the throat whatever, and in others this color is faint and restricted 

 in area. The differences are so striking as to be almost of specific 

 value. Measurements (in millimeters) of the specimens at hand 

 range as follows : 



Six males, wing 133.0-136.5 (134.5); tail 213.0-236.0 (221.3); 

 culmen from base 44.0-52.7 (48.8); tarsus 34.9-37.0 (36.3). 



Three females, wing 133.0-139.0 (135.2) ; tail 217.0-232.0 (223.0) ; 

 culmen from base 44.5-47.0 (45.3); tarsus 38.5-40.0 (39.2). 



Type specimen, male, wing 136.0, tail 224.0, culmen from base 44.0, 

 tarsus 37.0.
