over, and, of course, internal to the muscular bands, which 

 was spread over with a small quantity of brown grumous 

 matter ; but I saw no organs which could be supposed sub- 

 servient to the office of respiration there. 



The worm, having been kept in sea water unchanged for 

 two or three days, sickened, and, by the more frequent in- 

 volutions and evolutions of its oral end, evidenced its uneasi- 

 ness. Being left unobserved in this state for an hour or so, I 

 found, on my return, that it had vomited up its tentacula, its 

 oral apparatus, its intestinal tube entire and as exhibited in 

 our figure (c), and a large cluster of ovaries, which lay 

 about the plate ! The muscular convulsion must have been 

 very great that thus so completely embowelled the creature ; 

 and yet life was not extinct, for the tentacula contracted them- 

 selves on being touched; and the empty skin appeared, by its 

 motions, to have lost little of its irritability. It is true, as 

 the poet has long since sung, that 



" Nature's store 



Of majesty appeareth more 

 In waters, than in all the rest 

 Of elements."

lations, and of a uniform 

 flesh colour. On the upper 

 side a small vessel is seen dis- 

 tinctly, running down the 

 middle of the body, having a 

 tortuous course, and termi- 

 nating near the sucker; and 

 it lies over a much larger in- 

 testine, following the same 

 direction, and alone visible 

 on the ventral aspect. The 

 anterior extremity is rounded, 

 somewhat raised above the mouth, which is placed in a 

 sinus here, and opens chiefly on the under side; it is wide, 

 edentulous; but, when opened, the inner surface appears 

 flocculent, being clothed with longish papillae, which are 

 arranged in close longitudinal series, and cover the whole 

 intestinal canal. This organ is nearly of uniform width and 

 structure throughout ; but the papillag appear to be longer 

 towards its termination, which is by a small aperture on the 



Ph;f nine gr6ssa : a, u^per side ; b, under side.
