30 DEVELOPMENT OF 



Compare also, on this subject, R. Wagner's researches 

 on Coryne aculeata, which were carried on in the Adri- 

 atic in the year 1832. (Isis 1833, p. 256, tab. xi.) 

 That the bell-shaped animal frequently produced ova, and 

 consequently are females, has long been remarked, for 

 which we may refer to Loven's excellent memoir on Syn- 

 coryne ramosa of Sars, in ' Svenska Vetenskaps Akade- 

 miens Handlingar, (Aar 1836,) which also appeared in 

 ' Wiegman's Archiv für 1837,' (s. 322, tab. vi,) and to 

 R. Wagner's figure of Coryne vulgaris, in his ' Icones 

 Zootomic :' (1841, tab. xxi, fig. xvi.) 



Still more, however, do the conditions of Sars' new 

 animal, Corymorpha nutans recall what is exhibited in my 

 Coryne fritillaria. In order to compare them, I have 

 placed Sars' figure of the bell-shaped bodies of the 

 former, next to mine (fig. 47.) Sars expressly remarks, 

 that the four angles terminate in as many knobs, and that 

 one of these is always larger than the rest, and supports 

 a smaller rounded protuberance. In this description 

 will be easily recognized the lobated generative organ 

 present in the detached form of the animal. 



The notion promulgated by Sars (Beskrivelser, s. 25,) 

 and referred to by Loven (1. c. p. 322,) that the bell- 

 shaped body detaches itself and becomes a Coryne or club- 

 shaped Polype, and that the above-described tubercle at 

 One of the angles is lengthened into the stem of the 

 polype, will certainly be shared in by no one, and no 

 longer maintained by Sars himself. 



Any transformation of the bell-shaped into the clavate 

 form, or into a Coryne, I must consider as altogether im- 

 possible, from considerations of the structure of each, 

 and of the facts we have already obtained on the subject, 

 although a direct observation of a former period would 

 appear to show that it does occur. 



O. F. Müller, ' Zool. Dan.' (p. 3, Danish edition, p. 13,) 

 for instance, asserts, that the detached capsules are de- 

 veloped into new polypes. According to my opinion the 

 beU-shaped individuals are full-grown and fully-developed
