upon it : they differ considerably in length ; those that are near the 

 edge of the calyx being but small papilla^, in proportion to those that 

 surround the disk, or the central ])art 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." Gcertner. 

 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, hody conoid, variously coloured, rough icitk 

 glandular warts or sometimes smooth ; tentacxda numerous, in 3 

 or 4 series, shorter than the diameter of the oral disk, thick, and 

 generally variegated with red and v;hite rings.
