 Panama, in Salvin' s collection, is precisely similar. 

 We have examined the following specimens : — 

 One, Costa Rica (Carmiol), Mus. S.&G. ; two, Panama 

 (Arce), Mus. S.&G.; one, Costa Rica {Endres), Mus. S.&G.; 

 one, Panama {McLennan), Mus. S. & G. ; one, Panama

XXXII. — On two Species of Trochilidse of the Genus Lo- 

 phornis. By Osbert Salvin, M.A. &c, and D. G. Elliot, 

 F.L.S., F.Z.S., &c. 



In Schreibers's ' Collectanea ad Faunam Brasilise/ 1833, the 

 species generally known to authors as Lophornis gouldi (Or- 

 nismya gouldi, Less.) is described and figured as Trochilus 

 regince. It is impossible to decide which of these names takes 

 precedence, as Lesson's work on the Trochilidae extended over 

 more than one year in its publication, and therefore the 

 exact date at which his name was first given cannot be accu- 

 rately ascertained. Rather than disturb, therefore, a name by 

 which the species is everywhere known, by the substitution of 

 regince of Schreibers, which possibly may have a slight priority, 

 we have deemed it best to place Schreibers's name among the 

 synonyms of gouldi. In either case, however, whether regince 

 or gouldi have precedence, it becomes necessary to give a 

 new name to the very distinct species described as regince by 

 Gould in 1847, many years after the term had been employed 

 by Schreibers. 



The synonymy of the two species will be somewhat as 

 follows : —
