The word hirondelle, in French, is ufed as a general 

 term for the four *.fpecies of thefe birds, as the 

 term f wallow is with us. 



Now the four fwallows thus caught and examined 

 by Monf. Adanfon were either all of the fame 

 fpecies, or intermixed in feme other proportion. 



Would not then any naturalift in Mating fo ma- 

 terial a fact (as he himfelf fuppofes it to be) have 

 particularized of what fpecies of fwailow thefe very 

 interefting birds were ? 



Should not Monf. Adanfon alfo have taken care to 

 diftinguifh thefe iuppofed European fwallows from 

 two fpecies of the fame tribe, which bear a general 

 refemblance to thofe of Europe, and are not only 

 defcribed, but engraved by BrirTon, under the name 

 of Hirondelk de Senegal G? Hirondelle de rivage du 

 Senegal -f ¥ 



Though Monf. Adanfon was above a year on 

 this part of the African coaft, paid fo much atten- 

 tion to fwallows, and was fo immediately acquainted 

 with the different fpecies on the firft infpection, yet 

 he feems never to have difcovered that there were 

 fuch African fwallows as are thus defcribed and en- 

 graved by BrifTon, though he muft have feen them 

 daily. 



Monf. Adanfon however concludes his account of 

 the fuppofed European fwailow, whilft it continues 

 on the coaft of Senegal, by a circumflance which

 and the fwift : I omit the goatfucker, becaufe this bird, though 

 properly claffed as a fpecies of fwailow by ornithologifts, is not 

 fo confidered by others.
