The name Chelidon Forster has recently been revived by Dr. E. 
Hartert 1 as the proper generic appellation for Hirundo rustica and 
its allies, on the ground that Schaeffer? did not fix the type of 
Hirundo as HMirundo rusiica, and that Forster,* as the first author to 
subdivide the group, thereby determined its type. While it is quite 
true that Schaeffer in 1774 did not in the modern sense fix the type of 
the genus Hirundo, it is likewise true that the action of Forster in 
merely applying different generic names to several of the species is 
equally of no effect. The International Code of Nomenclature pro- 
vides that in order to make a type designation valid an author 
must definitely indicate a species as the type. So far as we have 
been able to ascertain, the first designation according to the speci- 
fications of the International Code was by Selby in 1825,4 who 
selected Hirundo rustica as the type; and Gray, in 1840,° designated 
the same species. There is thus open, under the rules, no other 
course than to consider Hirundo rustica the type of Hrundo 
Linnaeus.
