upper end, but grow sensibly wider towards the lower: the outermost of these 

 tubes are narrow, the middle are broader, and all of them have striae crossing 

 them; the distances between their parts are smooth, and appear hollow; their 

 superficies are wider at the top, and grow sensibly narrower towards the bottom. 

 All the tubes are hollow on the inside, forming cavities between the lines, both 

 simple and branched, which compose them. They arise from the orifice in 

 the middle of the inner part of the shell, and proceed towards the sides; the 

 branched part being nearest the side of the shell. 



As to the animal; in the upper part there appeared something like a gaping 

 mouth ; the upper and lower parts were both semicircular, but narrower towards 

 the point of the aperture; they were membranaceous, and took their rise from 

 the inside of the shell. The upper lip, if I may so call it, was altogether mem- 

 branous; the lower seemed of an osseous consistence towards the shell, and ap- 

 peared like the denies molares: a little below the mouth appeared the cirrhi, 

 which were continued with the rest of the body of the animal. I doubt not 

 but when the animal is alive, the under part below the cirrhi resembles the 

 under part of the mollusci of thepolypode kind: this resembles the parenchyma 

 of a buccinum, but was much firmer, and when piessed it yielded a fat juice; 

 it was white without, but blackish where it adhered to the shell ; it was all 

 contracted within the under part of the shell, which it filled: it was somewhat 

 exsiccated, so that I could not perceive any distinction of parts in it, though 

 some are of opinion there may be viscera and other vessels traced in it, when 

 the animal is newly taken. There are two sinewy bodies, which arise from the 

 sides of the upper part of the shell, exactly opposite to each other, and end as 

 it were in two claws; by these it is probable the animal attaches itself to any 

 thing; and by these it hung to the whale; it can dilate and contract them at 

 pleasure. This animal is a new species of the polypus kind, which seems to be 

 peculiar to some sort of whales in our northern seas.
