HIRUNDO FRANCICA. 

 Inhabits India, &c. 



HIRUNDO ACUTA. 

 Sharp tailed Swallow. Inhabits Martinique. 



HIRUNDO CAYENENSIS; 

 Five inches long. Inhabits Cayenne. 



HIRUNDO SINENSIS. 

 Inhabits China. A foot long. 



The Fauna Suecica, and also Brown in his 

 Jamaica, class the Caprimulgi Europeus and 

 Americanus among the swallows. 



I might add the sea swallows ; Sterna hirundo, 

 Sterna minuta, the Sandwich tern, and others of 

 the genus. Some of these may have been mistaken 

 by some writers for swallows. But the accounts 

 which I have received of swallows being seen at 

 sea, are explicit enough to determine them not to 

 be terns, though they are not satisfactory as to 

 what species of swallow*.
