 the feathers of the sides of the neck and in the greater size of the

 known.

The species described by me at the meeting of June 9, 1846, 

 {ante, pp. 44, 45) were 



18. Trochilus (petasophora) corūscans, a beautiful species al- 

 lied to the Anais, but whose locality is unknown to me. 



19. Trochilus ( .?) flabellifera, which is nearly aUied to, 



but a much larger species than T. mellivora, said to inhabit Mexico ; 

 and 



20. Trochilus ( ?) strophianus, a fine new species of the 



šame form as the Clarisse and the Parzudaki.
