292 Rev. T. Hincks's Catalogue of Zoophytes 



from a little below the polype, and " these secondary stems in 

 like manner give off tertiary stems/' the capsules being often in 

 such cases axillary. In the compound specimens of Campanu- 

 laria, as I have before pointed out (Report of Brit. Assoc, for 

 1858), a near approach is made to Laomedea, the leading cha- 

 racters of which are here assumed. On the other hand, in the 

 L. angulata, described in a previous portion of this catalogue, 

 and in one state of L. lacerata, the capsules are no longer axil- 

 lary, but are produced on the creeping stem. 



The Laomedea gracilis of Sars is a species which exactly re- 

 sembles, in habit and mode of branching, the compound form of 

 CampanulariaJohnstoni ; and he seems to have had much difficulty 

 in deciding under which genus to rank it. The branching of 

 Campanularia is simply a form of luxuriant growth, due, no 

 doubt, to favourable conditions of life. 



In the ' Edinb. New Phil. Journ.' for April 1858, Dr. Wright 

 has given an interesting account of the production of ova by the 

 medusoid of this species. In the same year in which his paper 

 appeared, I had made, but not published, similar observa- 

 tions. It will complete the history to mention that I noticed 

 the spermary as well as the ovary. In some of the globular 

 enlargements on the radiating canals, a rapid movement of 

 extremely minute bodies (spermatozoa) was visible, whilst others 

 contained the ova as described by Dr. Wright. 



3. C. Hincksii, Alder. 



Common: very fine on Sponge, &c, Salcombe Bay; Torbay, 

 very abundant on other zoophytes, in moderate depths (8 to 

 about 15 fathoms). 



The cells of this species are remarkable for their size. Mr. 

 Alder's otherwise excellent figure hardly does justice to this 

 characteristic. The gonothecse are elongate-oval and smooth. 



4. C. raridentata, Alder, MS. 



Not uncommon : between tide-marks, on Coralline and Co- 

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

 stuff. 



This species has not yet been published. The pedicles are 

 short, and there is a curious enlargement at the base of them ; 

 the cells are elongate, narrow, and with six pointed crenations 

 round the margin. 



5. C. verticillata, Linn. 



Very common in the Coralline zone : of great size amongst 

 the refuse of the trawl-boats ; dredged in Slapton Bay.
