These observations must have been written from a very 

 indistinct recollection of ^1. d'( )rbip,ny's excellent and detailed 

 ])aper and plate ; for he not oidy figures the exterior of the 

 animal, but also gives a longitudinal section of it, showing 

 the inside of the arms, the mouth and the visceral cavity, de- 

 tails of the arms and armlets, and the articulating surfaces of 

 which they are composed. Nothing like these articulations 

 has ever been found in any cirriped. 



i\lr. llawson, knowing nothing of any doubt on this subject 

 having been expressed, at once recognized it as a crinoid, 

 showing the justice of Rang's position of it ; and the organi- 

 zation of the crinoid is so unlike that of any recent or fossil 

 genera I know, that I think authors have been justified in 

 forming it into a separate family, characterized by its bag-like 

 body covered with a continuous calcareous coat, and attached 

 by its outer surface to submarine bodies. 



There are certain points in which the form of the arm 

 in Mr. llawson's figure is very unlike that of the species from 

 Martinique which D'Orbigny has called H. Rangii. I would 



* I can find no figure of the genus in my copy of the ' Annates.'
