A, The common masses, of the natural size, on a small stone. 



B, A single animal removed, and much magnified. 



Description. Common body subglobose or papillary, gela- 

 tinous, of a clear honey-yellow colour marked on the upper 

 surface with white and brown specks from the contained 

 animals; orifices circular, protuberant, plain, and entire. 

 Animals distinct, scattered irregularly, each in its proper cell, 

 perpendicular, about two lines long. Branchial aperture [a) 

 divided into 6 equal short segments ; the sac (b) large, white, 

 netted on the sides with minute square meshes, w^hich, how- 

 ever, are very obscure ; oesophagus (c) narrow, entering late- 

 rally at the upper side of the stomach {d\ which is large, 

 yellowish brown, and mottled ; intestine {e) dark-coloured, 

 wide, flexuose, recurved and winding up at the side of the 

 branchial sac ; anal aperture {/) elongate, linear, entire, 

 lateral, and near the mouth ; ovary [g) white, cellulose, at the 

 base of the intestine, with a long white tubular canal running 

 up and along the middle of the intestine, and terminating in 

 the branchial cavity. Differs from Aplidium ficus in having 

 the apertures in the common envelope entire, whereas, in the 

 A. ficus they are distinctly cut into 6 equal rays. See Ellis, 

 CoralL tab. 17. fig. b, c, d. Hab. Affixed to old shells, &c. 

 from deep water in Berwick Bay.
