Rev. T. Hincks on new species of British Zoophytes. 129 



sometimes in pairs^ one on each side of the fibre, sometimes 

 singly, sometimes in companies, are elongate, attached by a 

 short stalk, adnate, except at the anterior extremity, which bends 

 upward, and terminates in a roundish aperture. They are com- 

 monly laid alongside the fibre, and often appressed to it, but 

 occasionally stand out from it.

Cellularia cuspidata (Busk), — a British species. 



Mrs. Gulson has kindly supplied me with a specimen of this 

 Cellularia, which she obtained from the refuse of one of the 

 Brixham trawl-boats. It is a well-marked species, allied to 

 C. Peachii, and is common in Australia. Collectors in the South 

 should be on the look-out for it. Like the Caber ea Boryi (Busk), 

 it may prove, when attention is directed to it, to be far from 

 uncommon. 



There is a description and figure of C. cuspidata in Mr. Busk^s 

 ' Catalogue of the Polyzoa in the British Museum.' 



Caberea Boryi. 



Of this exquisite species, which is one of the latest additions 

 to our fauna, I have been fortunate enough to procure several 

 small tufts during the past autumn. They were dredged off Bud- 

 leigh Salterton (Devon), on much the same ground as yielded 

 Miss Cutler's beautiful specimen — the first recorded as British. 

 They were, for the most part, growing in the midst of a mass of 

 Scrupocellaria scruposa. The species being small, and bearing 

 a general resemblance to some of the commoner members of its 

 tribe, may readily escape detection, but it seems probable that, 

 at least on the Devonshire coast, it is far from rare. 



Beania mirabilis, — the Polype. 



The Polype of this species is, I believe, as yet undescribed. 

 It has about twenty long and delicate arms, forming a singularly 

 graceful bell, slightly everted round the rim. When fully ex- 

 tended, it protrudes very far beyond the orifice, — the body at 

 such times only occupying about the upper third of the cell. A 

 long, straight oesophagus leads from the pharynx to the stomach. 

 The fiexible portion of the cell, which unrolls as the animal 

 issues (and which has no operculum of setce),!^ of remarkable 

 length. Amongst the Polyzoa I know of no polype which 

 excels this in beauty, unless it be that of the (so-called) Flustra 

 hispida. An examination of its structure justifies Mr. Busk's 

 removal of the genus Beania from the family of the Vesicu- 

 lariadce.
