noble: the resident birds of Guadeloupe. 383 



this bird is very like a wood-warbler reminding one particularly of a 

 Black-poll {Dendroica striata). 



32. HoLOQUiscALus guadeloupensis (Lawrence). 



Holoquiscahis martinicensis Ridgway. 

 Merle. Bout de Petun. 



Nine specimens, adults and half-grown males from Ste. Rose, July 

 12th-18th; four specimens from Basse Terre, July 3d. 



I fail to find any characters by which to separate H. martinicensis 

 from H. guadeloupensis. Ridgway (Bull. U. S. N. M., 1902, 50, 

 pt. 2, p- 232) says of H. guadeloupensis "Similar to H. martinicensis 

 but wing averaging slightly longer." His measurements for the wing 

 of the male of H. martinicensis are: — 119.4-124 (120.7) and for the 

 female 102.4-108.5 (105.4). For the male of H. guadeloupensis, on 

 the other hand, his wing measurements are: — 119.9-124.5 (121.9), 

 for the female 104.4-109.2 (106.7). 



My averages for the wing of H. guadeloupensis are also slightly 

 larger than those of H. martinicensis, but this difference is very small, 

 and there is, apparently, no other distinguishing character. I do 

 not believe a distinction can be made between the two forms, and it 

 seems best to refer the ^Martinique bird to H. guadeloupensis. On 

 geographical grounds alone there would seem to be a real difference 

 between these two birds for the species has never been taken on 

 Dominica, lying just between and in plain sight of Guadeloupe and 

 Martinique. But if isolation has tended to make a distinction be- 

 tween the two forms, this distinction is, to my mind, at present not 

 great enough to recognize two species.
