266 Z. ASCIDIOIDA. Anguinaria. 



Hab. On Pinna ingens in the liarbour of Kinglade, 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. divaricata, t. 10, f. 15, 16, Lamou- 

 roux, Expos, but he describes and figures the cells as fusiform, and 

 not ovate, lanceolate, and his is fi'om a Fucus." Gray. 



29. Anguinaria, * Lamarck. 

 Character. Polypidom calcareous, creeping, adnate, slen- 

 der, Jistular, the cells scattered, erect, free, spathulate, tvith 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.
