290 POLYZOA INFUNDIBULATA. 



The polype " protrudes itself through a small opening at the 

 upper margin of the cell, and the large opening seen in the dead 

 specimen on the anterior surface of the cell, is in the living spe- 

 cimen covered in by a memhrane. The polype has from ten to 

 twelve ciliated tentacula about half the length of the cell." J. Reid. 



9. ANGUINARIA,* Lamarck. 



CHARACTER. Polype cells spathulate, erect, scattered, with a 

 lateral aperture near the apex, originating from a creeping fis- 

 tular sulcalcareous fibre adnate to a foreign base. Polypes 

 ascidian.

Hdb. Parasitical on the smaller sea-weeds, not common. " In- 

 vests those algae chiefly whose stems are clothed with hair-like 

 fibres, as Dasya coccinea, Griffithsia equisetifolia, and Sphacellaria 

 scoparia ; but found occasionally on smooth stemmed species, as 

 Plocamium coccineum," W. Thompson. 



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 

 polypous production, and he felt inclined to class it near to or with 



* From unguis, a snake, to the head of which the cells of the Anguinaria have 

 some resemblance.
