Nephoecetes niger guadeloupensis CORY: Type from Guadeloupe Island, Lesser

 C. S. Winch, August n, 1890. Similar to N. n. jamaicensis (RIDGWAY) from Ja- 

 maica, but averaging smaller and general color averaging darker. Wing, 144; tail, 

 63 (average of 8 specimens, wing, 145; tail, 6p). I have not seen specimens of the 

 Black Swift recorded from Dominica, Martinique and St. Vincent, which are prob- 

 ably this form, or from British Guiana (Merume Mts.) which may prove to be this 

 or another form.
