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

 family, comprising those species distinguished by the extraoidinary 

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

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

 species known frequent the mountain districts of the Cordillerian 

 Andes or the valleys immediately beneath them. 



I possess five species of this forra, and I have seen tvvo others 

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

 typical.

4. An ACCOUNT OF Palolo, A Sea Worm eaten in the Navigator 

 IsLANDS. By the Rev. J. B. Stair, wiTn a descriftion 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 Rluseum, but unfortunately most of the 

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

 able to discover any specimen w'ith a head. It appears to be a new 

 genus allied to Arenicola, \vhich may be thus described : — 



Palola, Gray. 



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

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



? Lašt joint ending in a couple of tentacles. Eggs glo- 



bular.
