tarsi thickly clothed with downy feathers, forming a thick ruff round 

 the leg. 



Sexes nearly alike in colour. 



Type, E. vestita, 



I beg to propose the above generic appellation for a section of this 

 family, comprising those species distinguished by the extraordinary 

 ruffs of downy feathers with which their tarsi are clothed, and by the 

 sexes being nearly alike in the colour of their plumage. All the 

 species known frequent the mountain districts of the Cordillerian 

 Andes or the valleys immediately beneath them. 



I possess five species of this form, and I have seen two others 

 in the collection of Mr. Loddiges, which I believe to be equally 

 typical.

 This group forms part of M. Lesson's Race Vestipedes, the genera 

 comprised in which have not as yet I believe been defined. 



4. An account of Palolo, a Sea Worm eaten in the Navigator 



Islands. By the Rev. J. B. Stair, with a description by 



J. E. Gray, Esq., F.R.S. etc 



The Rev. J. B. Stair kindly presented numerous specimens of this 



Sea Worm to the British Museum, but unfortunately most of the 



specimens are broken into short pieces, and as yet I have not been 



able to discover any specimen with a head. It appears to be a new 



genus allied to Arenicola, which may be thus described : — 



Palola, Gray. 



Body cylindrical, separated into equal joints, each joint with a 

 small tuft of three or four spicula on the middle of each side. Head 

 ? Last joint ending in a couple of tentacles. Eggs globular.
