liio-ly delicate, and have at fmall diftances fibres running acrofs 

 them from then* attachment at the fi:em to the loofe edge, 

 which gives them a ribbed appearance. Thefe fibres are conti- 

 nued about one-tenth of an inch beyond the membrane, having 

 their edges finely ferrated, like the tentacula of the Adinise 

 found in Barbadoes : thefe tentacula (liorten as the fpiral turns 

 become fmaller, and are entirely loft in that part of the mem- 

 ■brane which terminates in the point of the cone. 



Behind the origin of thefe cones arifes a fmall fhell, which, 

 for one-fixth of an inch from its attachment to the animal, is 

 very (lender: it is about three quarters of an inch in length, 

 becoming confiderably broader at the other end, which is flat, 

 and about one-third of an inch broad; the flattened extremity 

 is covered with a kind of hair, and has rifmg out of it two 

 fmall claws, about one-fixth of an inch in length. If the hair, 

 •and mucus entangled in it, be taken away, this extremity of the 

 fhell becomes concave, is of a pink colour, and the two 

 claws rifing out from its middle part have each three fliort 

 -branches, not unlike the horns of a deer. The body of this 

 ■fhell has a foft cartilaginous covering, with an irregular but 

 poliflied furfacet on this the cones red in their collapfed ftate, 

 in which ftate the whole of the fhell is drawn into the cavity of 

 the brain-ftone, excepting the flattened end with the two 



-claws. 



Before the c6nes there is a thin membrane, which appears to 

 be of the fame length vv'ith the fliell juft defcribed. In the col- 

 lapfed ftate it lies between the cones and the fliell in which trie 

 animal is inclofed ; but, when the tentacula are thrown out, it 

 •is alfo protruded. 



The fhell of this animal is a tube, which is very thin, and 

 adapted to its body: the internal furface is fraooth, and of a
