This extraordinary Sea-Pen was difcovered by Dr. Bo- 

 hadfch, of Prague, while he was at Naples in the year 

 1757. He fays, when it was brought to him, it was 

 two feet ten inches long, and very poffibly had been much 

 longer, as it was broke off at the Safe. 



The bone, which was fquare, was covered over with a 

 yellowiih membrane, and three fides of the upper part of 

 the trunk were covered with tentacles, the fourth, bare. 

 Pie fays, he numbered them, and found 13 10, and that 

 thefe tentacles are not drawn in, as in the other Sea-Pens. 

 Other authors mention, that the tentacles are only on one 

 fide ; but Dr. Bohadfch had an opportunity of feeing it 

 as it was taken out of the fea.

This very fmall animal, according to Dr. Linnaeus, is 

 found (ticking in the fifh, called by him Lophius Hiftrio, 

 having its ftern pierced into their fides. 



The figure in the Philofophical Tranfactions is copied 

 from Linnaeus's Amoenitates, Vol. 4. tab. 3. fig. 13. 

 having never (ccn it myfelf. For my own part, I am 

 doubtful whether it belongs to this genus.
