upon it : they differ considerably in length ; those that are near the 
edge of the calyx being but small papillae, in proportion to those that 
surround the disk, or the central part of the body. They are almost 
transparent ; and some of them are of a pale ash colour, with brown 
spots ; others, on the contrary, are of a chesnut colour, marked with 
white spots. The disk is formed like a star, which, according to the 
figure that is traced out by the innermost row of the feelers, consists 
of many angles. The colour of this part of the body is a beautiful 
mixture of brown, yellow, ash-colour and white, which together form 
variegated rays, that from the centre, or the mouth of the animal, are 
spread over the whole surface of the disk. This polype contract- 
ing itself, changes its body into an irregular hemisphere, which is so 
covered with the several extraneous bodies that stick to it, that it is 
extremely difficult to know the animal in this state, and to discern it 
from the rubbish, that commonly surrounds it.” Gartner . 
Perhaps a variety of the A. gemmacea.

“ When contracted, the body seems like two broad rings, of near, 
ly equal breadth, and about half an inch in diameter ; when expand- 
ed to nearly two inches, the body consists of two cylindrical portions 
of different dimensions, smooth, pellucid, yellowish ; a few longitudi- 
nal white streaks under the skin ; oral disk not expanded, surround- 
ed with about 18 filiform tentacula in two alternate rows.” Fleming, 
4. A. gemmacea, body conoid , variously coloured , rough with 
glandular warts or sometimes smooth ; tentacula numerous , in 3 
or 4 series , shorter than the diameter of the oral disk } thick , and 
generally variegated with red and white rings.
