HIRUNDO, CHELIDON, and COTILE. 



It has almost nnanimously been considered, tliat Bote (Isis, 1822), 

 was the first who subdivided the genus Hirundo after the species be- 

 longing to Cypselus had been removed, and consequently his names 

 Hirundo (type riistica LiN.), GlieUdon (type urhicaljUi.)., and CoUle (type 

 riparia Lin.) have been generally adopted. The same species, how- 

 ever, had already five years earlier been made types of three different 

 genera, by Thomas Forster, who, in his " Synoptical Catalogue of 

 British Birds" (London, 1817), establishes the genera Chelidon, Hirundo 

 and Clivicola, having as tyi^es respectively rustica, urhica, and riparia. 



These names, which are as well founded as the later names of BoiE, 

 cannot, so fiir as I can see, be rejected. Mr. Forster himself states, 

 p. 40, that he has " in the following catalogue attended to generic and 

 specific differences, and thereon founded a nomenclature, regardless of 

 the modern names, wherever they appeared to disagree with facts." • 



I suppose the following will stand as the correct synonymy : 



CheUdon Forster, 1817. 



< 1758.— ffiriwcio Lin. S. N. ed. 10, I, p. 191. 



= 1817. — CheUdon Forster, Syu. Cat. Brit. B. p. 55 (nee Boie, 1822), (type H. rustica 



Lin.). 

 =1822.— Hirundo Boie, Isis, 1822, p. 550 (nee Forster, 1817), (same type). 



Of this genus we only have one species in North America, viz : 

 1. CheUdon erythrogastra (BoDD.), Barn Swallow. 

 The European species are : 

 CheUdon rustica (Lin.), and 

 CheUdon savignii (Steph.).
