 TUBUCELLAEIA HIESUTA (Busk). 



[Genus TUBUCELLARIA (D'Orbignt) = ONCHOPORA (Busk) in part. (Sub-kingd. 

 Mollusca. Class Polyzoa. Order Infundibulata. Sub-Order Chielostomata. Fam. Salicor- 

 nariidse.) 



Gen. Char — Cells convex, ventricose, confluent, indistinct; mouth produced into a tube ; 

 no raised margin, and no aperture.] 



Description. — Polyzoary of rather short internodes ; mouth prolonged forwards 

 into a slightly projecting- tube ; on each side below the tubular portion a long", hollow, 

 jointed, tubular process is articulated. 



Reference. — Onchopora id., Busk, Mic. Journ., vol. iii., p. 320.

This very peculiar species occurs in tufts, 1 to 2 or 3 inches 

 high. The internodes are short and thick. The cells are of 

 large size ; the surface (in dried specimens) divided into minute 

 areas bordered by chain-like rows of small punctations. The mouth 

 of the cell projects slightly in a tubular form, and on each side, at 

 the commencement of this projection, is a long, hollow, jointed 

 corneous process. This is quite different from the radical processes, 

 which are of about the same thickness, and may be occasionally seen 

 at the base of an internode, twisted cable-like and curled at the 

 ends. There is in many cells a small round or oval, raised pore 

 below the mouth. This is frequently wanting, and is probably 

 an avicularium.
