GENERIC CHARACTER. Stems simple or branched, rising 

 from a creeping filiform and anastomosing stolon, the whole 

 invested by a polypary ; polypites fusiform, with a single 

 verticil of filiform tentacula round the base of a conical pro- 

 boscis ; f/onophores borne on rudimentary polypites, desti- 

 tute of tentacles, developed directly from the creeping stolon, 

 containing fixed sporosacs.

STEMS branched or simple, crowded on the creeping stolon, 

 the longest attaining a height of about 4 lines ; poly- 

 pary transversely corrugated, slightly dilated at the base 

 of the polypites, ash-brown ; POLYPITES with about 12 

 tentacles, alternately erect and depressed, presenting a 

 slightly clavate outline at their extremities; GONOPHORES 

 borne on erect, club-shaped shoots, thickly set with 

 thread-cells above, which spring out of a short tubular 

 process from the surface of the creeping stolon, with 

 very short peduncles, densely crowded, commencing a 

 little behind the upper extremity of the shoot and ex- 

 tending to within a short distance of its base. 



THIS species closely resembles, in general appearance, 

 Dicoryne conferta ; but it is of humbler growth and some- 

 what stiffer habit, and is further and chiefly distinguished 

 by its simple, fixed sporosacs. 



Hab. The Harbour of Glengariff, co. Cork, on old uni- 

 valve shells tenanted by Hermit Crabs (G. J. A.) : Oban, 

 on Buccinum, near low- water mark (T. H.).
