Z. ASCIDIOIDA. 
Anguinaria. 
Hab. On Pinna ingens in the harbour of King-lade, near Cork, 
Miss Elliot. 
“ Coral attached, slender, dichotomously and divaricately branch- 
ed, pearly white ; cells slender, linear, ovate, base filiform, generally 
emitting a cell at right angles from the middle of each side ; mouth 
small, round, with a raised margin, placed near the top of the cell.” 
“ This species is very like H. divaricate t. 10, f. 15, 16, Lamou- 
roux, Expos, but he describes and figures the cells as fusiform, and 
not ovate, lanceolate, and his is from a Fucus .” Gray. 
29. Anguinaria, * Lamarck. 
Character. Polypidom calcareous , creeping , adnate, slen- 
der, fistular, the cells scattered, erect, free, spathulate, with a la- 
teral aperture near the apex . — Polypes ascidian.

Hab. Parasitical on the smaller Fuci, rare. Brighton, Mr Mac- 
gillivray. Scarborough, Mr Bean. “ Found on the shore at Carrick- 
fergus, on the sand,” Templeton. 
This remarkable coralline creeps along the stalks of the sea- weed 
it prefers in a wavy line, the capillary tube swelling out at irregular 
intervals, and sending up numerous clavate processes or cells, which 
are from one to two lines high, more or less bent at the top, of a 
pale pink or flesh-colour or white, smooth, glossy, calcareous; the 
aperture inferior, subterminal, oval, with plain margins. 
Lamouroux suspected that this might prove different from any po- 
lypous production, and he felt inclined to class it near to or with the 
Vorticellae, but the conjecture has been shewn to be groundless by 
Mr Lister’s discovery of its polypes, which are truly ascidian, and 
nearly allied to those of the Flustra. 
From Anguis, a snake.
