OCT., 1909. BIRDS OF THE LEEWARD ISLANDS CORY. 231 



Family Strigidse. 



Two unidentified Owls were seen by Mr. Lowe. (Ibis, 1909, 

 P- 3i3-) 



Family Alcediiiidte. 



Ceryle alcyon (Linn.). 



Several birds of this species were seen by Mr. Lowe on Testigo 

 Grande. It was not noted by Mr. Ferry. 



Family Trochilidae. 



Chrysolampis mosquitus (Linn.). 



Mr. Lowe found this species on one of the smaller islands of the 

 group, but did not observe it on Testigo Grande. (Ibis, 1909, p. 317.) 



Family Tyraimidfe. 



Myiarchus tyrannulus (Mull.). 



5 specimens taken, 2 cT, 3 9 , all of which agree very well in size 

 and coloration with birds from Margarita. 



Family Icteridse. 



Holoquiscalus insularis (Richmond). 



1 8 specimens, n d\ 7 9. 



I cannot agree with Mr. Lowe in considering the bird which is 

 found on Los Testigos to be H . luminosus. While the variation in 

 size and terminal decurvature of the bill is considerable, specimens 

 occur which agree fairly well with insularis, and the female is nearer 

 in coloration to that species and may be readily distinguished from 

 females of H. luminosus from Grenada, as represented in the series 

 in this Museum. Birds from Testigos Islands seem to be inter- 

 mediate between insularis and luminosus and may represent a slightly 

 differentiated form; but it would seem undesirable to cumber orni- 

 thological nomenclature with a name based upon slight and apparently 

 inconstant characters.
