Observation. 

 The name of this genus is derived from the Greek AIIION, pear. 



None of its species have as yet occurred in a living state, and those found 

 fossil, are of local occurrence, and confined as to geological place to strata 

 more recent than the lias. 



One of the species is proved to be permanently adhering, whether the other 

 was so has not been ascertained. 



I. SPECIES APIOCRINITES ROTUNDUS. 

 ROUND COLUMN'D PEAR-LIKE LILY-SHAPED ANIMAL. 



Specific Character. 



A Crinoidal animal, with a round column composed of joints adhering by 

 radiating surfaces, of which from ten to fourteen gradually enlarge at its apex, 

 sustaining the pelvis, costae, and scapulae, from which the arms and tentacu- 

 lated fingers proceed. 



Base formed by exuding calcareous matter, which indurates in laminae, and 

 permanently attaches the animal to extraneous bodies.
