XV. — Further Notes on British Zoophytes, loith descriptions of 

 new Species. By the Rev. Thomas Hincks, B.A. 



[With two Plates.] 



It is with peculiar pleasure that I have to record the discovery 

 of two new species of the beautiful genus Campanularia in the 

 British Seas. The first which I shall describe is allied to the 

 Campanularia Syringa and the C. dumosa, and belongs to the 

 section of the genus which is distinguished by the " dense cor- 

 neous texture " of the cells and the shortness of the pedicle. 

 The only specimen which I have yet seen occurs on a fragment 

 of Nitophyllwn from the north of Ireland, and was sent me for 

 description by my father, Professor Hincks of the Queen's Col- 

 lege, Cork. 



Genus Campanularia. 

 i. C. parvula ijlxavks). 

 Stem creeping ; cells very minute, on short ringed stalks, campanu- 

 late, the aperture entire. 



The creeping stem is of great delicacy, and forms a rude kind 

 of network over the surface of the weed. The cells are exceed- 

 ingly minute, campanulate, of equal width throughout till within 

 a short distance of the base, when they are abruptly rounded 

 off; of a somewhat dense, corneous structure, and mounted on 

 very short stalks, composed of about four rings. The aperture 

 is truncate and the margin plain. 



This pigmy species is, I believe, the smallest of the ' Bell- 

 corallines,' and there is no other British form with which it can 

 be confounded. The shape of the cell is very distinctive, and is 

 well preserved in dried specimens.

ii. C. caliculata (Hincks). 



Stem o'eeping, filiform; cells on rather thick crenated stalks, 

 campanulate, having an interior cup which contains the body 

 of the polype, and is prolonged below into a tubular case, 

 which pervades the pedicle and envelopes the medullary pulp ; 

 rim entire. 

 This vei7 beautiful and interesting species was first obtained 

 by Mr. R. S. Boswell, lately of Ramsgate, from Pegwell Bay. In 

 the course of the past summer this gentleman showed me a spe- 

 cimen of it, amongst some other zoophytes, exquisitely mounted 

 according to a peculiar method of his own, and expressed an 

 opinion that it was new, an opinion in which I was much inclined 

 to agree with him. Within the last few weeks my friend Richard
