LOV^NELLA CLAUSA. 177 



occasionally (J. A.) : on coralline &c. between tide-marks, 

 Torquay ; on zoophytes, amongst the Brixham trawl-re- 

 fuse, not uncommon ; Swanage Bay, Dorset, common in 

 5-7 fathoms (T. H.). 



Genus LOVENELLA, Hincks. 



Der. Named after the distinguished Swedish naturalist, Loven. 



GENERIC CHARACTER. Stems simple or slightly branch- 

 ing, rooted by a thread-like stolon ; hydrotheca turbinate, 

 elongate, crowned with a distinct, conical operculum, com- 

 posed of many convergent segments ; polijpites with a large 

 and prominent proboscis. 



Reproduction unknown. 



THIS genus is distinguished from its allies by its long 

 (but not tubular) operculated calycles. Its polypite is of 

 the same type as that of Campamdaria.

STEMS simple or very sparingly branched, with a few rings 

 at the top and bottom, the intermediate portion crenated 

 or wavy ; branches short, simple, erect, supporting a 

 single calycle; HYDROTHEC^E hyaline, very long and 

 slender, tapering off gradually below, the rim cut into 

 shallow crenations, which correspond with the segments 

 of a turret-shaped operculum, composed of about 8 pieces 

 that converge and meet in a point ; POLYPITE with about 

 15 tentacles; GONOTHEC.E unknown. 



THIS beautiful species was characterized by Loven inci- 

 dentally in a note to his famous paper on Campanularia and 

 Syncoryna. It had not, I believe, attracted the notice of 

 any subsequent author; and supposing it to be new to
