of DevonJJiire, particularly at Milton fands in the foutli, 

 and Ufracomb in the north ; but is rarely procured alive, 

 except at very low tides, or by dredging. Doflor Pul- 

 TENEY fpeaks of it as„a rare (hell on the (hores oS. Dor- 

 fetjhire ; and we believe grows fcarcer eaftward. 



The animal is painted like its (hell, with two very long 

 filiform tentacula; beneath thefe, at the bafe, are two 

 fmall black eyes; clofe to which are two minute feelers, 

 or cirri, and on each fide is another, little inferior in 

 length to the tentacula ; thefe appendages are in conti- 

 nual motion, and are capable of turning in all direftions.

Tab. 12. f. 5. per in (hape, and finely reticulated: colour tranfparent

 tenth of an inch ; breadth one third its length. 



We found this elegant fpecies at Whit/and bay in Corn- 

 zvall, and in fand from Salcomb bay in DevonJJiire, but 

 extremely rare; its beauty is only to be feen under a 

 firong magnifier, as the work is extremely fine; by the 

 aid of a microfcope it appears delicately punflured all 

 over, and wrought with extremely fine decuflated ftriae.
