Tliis specimen as well as a ¥ I'roiu Toiiago are practically idenlical wilh a 

 (J from Grenada. All have the upper tail-eoverts Idackish with a slight steel-green 

 gloss, only a very narrow edge along the inner web being pale greyish ; tlic lower 

 surface is pure schistaceous, in strong contrast to the steel-black under tail-coverts. 

 C. c. quianeitsis Hart, of which form there are three examples from British 

 Guiana in the British Museum, differs in having the upper tail-coverts or at least 

 tiieir inner webs light schistaceous grey like the rump. 



According to Leotaud, the species is sedentary on the island.

It agrees perfectly with a typical specimen from Tobago. A series ot twenty 

 examj)les from Cayenne and Surinam is also absolutely identical. 



This is the bird commonly called C. poUura, but Temminck's name certainly 

 does not refer to the species in question. Ci/pselua poliouii.is Temminck * is 

 exclusively based on D'Aubenton's plate 720, fig. 2. Both the figure and the 

 description of the " Hirondelle brune acutipenne de la Louisiane" suit much better 

 the common North American Chaetura pelagica (Linn.); and, moreover, in the 

 letterpress Moutbeillard expressly states : " L'individu dont il est ici question a 6te 

 cnvoye de la Loiiisiani' par M. Lelieau." Tiience there is not the slightest donbt 

 that ('j/psdi(s poliourias must be regarded as a pure synonym of C. pclfujicn, which 

 is the only species found in Louisiana. Tlie next available name for the South 

 American s])ecies is A. hradnjHra.
