86 Rev. T. Hincks on the Reproduction of the Campanulariadse. 



In other respects they resemble those of L. geniculata. Each 

 vesicle contains about five of them. 



New species of Laomedea. 



Dr. Johnston describes and figures a species of Campanularia 

 under the name of C. lacerata. I have lately had the opportunity 

 of ascertaining that this is only the early state of a Laomedea 

 which has occurred to me in considerable abundance on the 

 Devonshire coast, and which is as yet^ I believe, undescribed. It 

 may be thus characterized ; — 



Laomedea lacerata (Hincks). (PI. III. fig. 6.) Stem filiform, 

 7-inged throughout ; cells on short pedicles, ovato-conical, the upper 

 portion divided into a number of deep convergent segments. 



This is the smallest of the British Laomedece and is of extreme 

 delicacy. The largest specimen which I have met with does not 

 exceed the sixteenth of an inch in height. 



The stems, which are slender and slightly ringed throughout, 

 rise from a creeping fibre and bear the cells on short pedicles, 

 composed of four or five rings, and somewhat irregularly dis- 

 posed. The cells are ovate, the upper part conical and cleft into 

 a number of deep segments, which converge and form an acute 

 apex. The polype when issuing pushes aside the pieces, which 

 close again upon its retreat. They form an admirable operculum 

 to the cell. 



In its young state this Laomedea is identical with the Campa- 

 nularia lacerata of Dr. Johnston's work. Single cells are fre- 

 quently met with, supported on short ringed pedicles, which 

 spring immediately from the creeping fibre, as represented in 

 Plate III. fig. 6 X. 



Laomedea lacerata was obtained abundantly in tufts of Bower- 

 hankia, and on weed, at Exmouth. 



I remain, Gentlemen, your obedient servant,

P.S. — In a paper entitled "Notes on British Zoophytes,^' 

 which was published in the ' Annals' for November 1851, I de- 

 scribed a species of Farrella as new, under the name of F, pro- 

 ducta. Since that time Mr. Wyville Thomson has directed my 

 attention to Van Beneden's figure and description of Laguncula 

 elongata, which I had not previously seen, and 1 have now no 

 doubt of the identity of the two species. 



The name F. producta must therefore be cancelled, and I would 

 substitute for my former note under this heading, a record of the 

 «'currence of the Laguncula elongata of Van Beneden {Farrella 

 ^ngata it should be) as a British species.
