MYIARCHUS BREVIPENNIS Hartert. 

 CURASAO CRESTED FLYCATCHER. 



Similar to M. tyrannulus, but tarsus longer, wings and tail shorter, 

 bill black, and coloration of upper parts paler; length, 185; wing, 

 86.4-88.9; tail, 88.9; culmen [ exposed ?] , 17.8-20.3; tarsus, 19-21. 6.^^ 



a I am unable to verify, from comparison of a single specimen from St. Christopher, 

 the color differences claimed in the original description. 



b One specimen, from St. Christopher. 



I refer doubtfully to this form, a series of Myiarchus from the island of Barbuda. 

 These agree with the specimen of M. o. berlepschi from St. Christopher in small size, 

 but are apparently slightly paler and more olivaceous in color of back, et(;., and the 

 upper tail-coverts are in all (five adults) strongly tinged with cinnamon or rusty. 

 The yellow of under parts is also brighter and clearer (more so even than in M. o. oberi) , 

 approaching sulphur yellow. Average measurements are as follows: Adult males: 

 Length (skins), 178-196 (189); wing, 88.5-95 (92.6); tail, 77-84.5 (82.3); exposed 

 culmen, 20-22.5 (21.2); tarsus, 23.5-24.5 (24.1); middle toe, 13-14 (13.5). Adult 

 female: Length (skin), 192; wing, 89.5; tail, 79; exposed culmen, 21; tarsus, 24.5; 

 middle toe, 13.5. 



c Specimens from Antigua and Nevis not seen by me. 



d Free translation of original description, the measurements (in inches and decimals) 

 converted into millimeters. I have not seen a specimen of this form.
