medial rectrices, which have nearly the ordinary normal form, by 

 nearly half an inch. In P. Jilicauda, as is well known, the rectrices 

 are nearly of equal length, and terminate in a long hair-like filament. 

 Further differences from Pipr a Jilicauda are observable in the crim- 

 son colour descending lower down the back above, and pervading the 

 breast and upper part of the belly. In the latter respect this species 

 approaches to P. aureola and its scarcely separable ally, P. flavicollis 

 of the Rio Negro, an example of which was in the same collection. 

 I propose to call this Manakin

Description of a New Tyrant-bird of the genus Elainea, 

 from the Island of Saint Thomas, West Indies. By 

 Philip Lutley Sclater, M.A., Secretary to the So- 

 ciety. 



Mr. Osbert Salvin landed at St. Thomas for a few hours on his 

 way out to Guatemala in the spring of last year, and with charac- 

 teristic energy took out his gun for a ramble. The first shot fired 

 secured two examples of a bird not previously known as an inhabitant 

 of this island*, and, I believe, new to science — a species of Tyrant- 

 bird of the genus Elaineaf. Mr. Riise, so well known for his col- 

 lections in different branches of Natural History made in this island, 

 having had his attention drawn to the existence of this bird by Mr. 

 A. Newton, caused a search to be made, and obtained six other spe- 

 cimens, which I now exhibit. It is to this gentleman that I propose 

 to dedicate this species, in commemoration of his exertions in con- 

 firming Mr. Salvin' s discovery, by the name of 



Elainea Rush, sp. nov.

t This genus of Sundevall has heen written in many differeiii; ways (sc. Elcenia, 

 Elainia, &c.) ; but the proper orthography is certainly Elainea, from eXaivos or 

 v eXatveos, oleagineus.
