The occurrence of this species on the mainland of Central America rests at present 

 upon two specimens in the collection of Messrs. Salvin and Godman, and now in the 

 British Museum. One specimen was procured by Mr. G. F. Gaumer in Yucatan, Avhere, 

 says that gentleman, it is resident, frequenting the cave-like holes called " senotes." 

 Another specimen, not fully adult, was obtained in Panama by the late Mr. M'Leannan, 

 and there can be no doubt that it is referable to the present species. Messrs. Salvin 

 and Godman suggest that there is a possibility of an error in the locality attributed to 

 this specimen, as M'Leannan once had some Cuban birds in his possession ; but it is 

 quite possible that on the continent of America the species is local and only to be found 

 in colonies, like its conveners, and thus it mav be distributed over a wider area than is 

 generally supposed. 



Dr. Thienemann has described eggs of this Swallow sent from Cuba by Dr. 

 Gundlach as being similar to those of its North- American relative, the ground-colour 

 being milky white without much gloss, and thickly covered with reddish grey, or else 

 with light or dark spots of a brownish-red colour. 



The descriptions are taken from the British Museum ' Catalogue,' and the figure is 

 drawn from the Yucatan specimen in the Salvin-Godman collection.
