F. DE Lafresnaye. 



Among the collections jiurchased by Dr. Wilson in Paris was 

 that of M. Delatre, obtained in Peru, Bolivia, Colombia and 

 Panama. This contained many novelties, and these were sub- 



mitted to Lafresuaye for publication before the collection was 

 shipped to America. His paper appeared in Ihe Revue Zoologiqv.e, 

 March, 1847, pp. 67-79, and in it eighteen new species were 

 proposed. The types of all of these are preserved in the collec- 

 tion, and their study proves of interest, as some of Lafresnaye's 

 names seem to have been entirely overlooked.

Lafresnaye's excellent description seems to have been entirely 

 overlooked and the bird has gone by the name of 0. citr'mifroiiA 

 Sclater, P. Z. S., 1862, p. 113, which must, however, become of a 

 synonym of 0. frontalis Lafr.
