3. Calicella (nov. gen.), Hincks. 



Polypary filiform, creeping or erect; cells somewhat densely 

 corneous, tubular, sessile or very slightly pedunculate. 



Type-species, C dumosa. 



The reproduction of this section of the Campanulariadse has 

 been very little studied as yet. I have described the gonophore 

 of C. syringa, and the structure of its reproductive organs (fe- 

 male), in the 'Annals' for August 1852; but I am not aware 

 that similar observations have been made in the case of any 

 other member of this genus. This is not a little remarkable, as 

 the C. dumosa is widely distributed, and occurs in profusion. 

 Amongst some thousands of specimens, examined from time to 

 time, I have never met with anything that threw light on the 

 history of its reproduction. 



The gonophore of C. syringa resembles in structure that of 

 Laomedea lacerata, L. neglecta, and some of the Sertulariadse, 

 the ova being matured in extracapsular marsupia. 



I find that, in constituting a genus for C. dumosa and its allies, 

 I have the support of Professor Reid, who, in his valuable paper 

 entitled " Anatomical and Physiological Observations on some 

 Zoophytes" ('Annals' for 1845, vol. xvi. p. 385), has remarked 

 upon this species, that " the characters of the polypidom separate 

 it from the genus Campanularia." 



1. C. dumosa, Flem. 



Very common in deep water : on Pinna from 60 fathoms, off 

 the Deadman (the erect form) ; amongst the trawl-refuse, &c. 

 A slender and delicate variety occurs occasionally. 



2. C. fruticosa, Sars, Beretning om en Zoologisk Reise i Lofoten 

 og Finmarken, pp. 18, 19. 



Syn. Campanularia gracillima. Alder, Catal. p. 39. 



jMr. Alder has received specimens from Plymouth or its 

 neighbourhood. 



Sars's name has precedence. His description of the species 

 appeared, many years since, in a paper which is now only to be 

 obtained with difficulty, and which is written in Danish. It is 

 very desirable that all new discoveries should be put on record 

 in some journal which has a European circulation, and that 

 there should be a freer and more spontaneous interchange of 

 publications amongst those who cultivate the same branches of 

 science. Much waste of time and perplexing multiplication of 

 names might thus be prevented.
