The word hirondelle , in French, is ufed as a general 
term for the four * fpecies of thefe birds, as the 
term fwallow is with us. 
Now the four fwallows thus caught and examined 
by Monf. Adanfon were either all of the fame 
fpecies, or intermixed in fome other proportion. 
Would not then any naturalift in Hating lb ma- 
terial a fadt (as he himfelf fuppofes it to be) have 
particularized of what fpecies of fwallow thefe very 
interefting birds were ? 
Should not Monf. Adanfon alfo have taken care to 
diftinguilh thefe fuppofed 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 BrilTon, under the name 
of Hirondelle de Senegal & Hirondelle de rivage du 
Senegal -f- ? 
Though Monf. Adanfon was above a year on 
this part of the African coaJf, paid fo much atten- 
tion to fwallows, and was fo immediately acquainted 
with the different fpecies on the firff infpedtion, yet 
he feems never to have difcovered that there were 
fuch African fwallows as are thus defcribed and en- 
graved by Briffon, though he muft have feen them 
daily. 
Monf. Adanfon however concludes his account of 
the fuppofed European fwallow, whilif it continues 
on the coaft of Senegal, by a circumftance which 
* Viz. the fwallow x«T e^o^v, the martin, the fand martin, 
and the fwift : I omit the goatfucker, becaufe this bird, though 
properly clalTed as a fpecies of fwallow by ornithologifts, is not 
fo confjdered by others.
