fom* radiating vessels which connect the two former. 

 Fig. 40, represents the whole vascular system in 

 connexion, as far as I have been able to trace it. 



Figs. 41-47. The Development of the Club-shaped 

 Polype, Coryne fritillaria. 



N.B. (The figures are after my own drawings, 

 from specimens observed in Iceland. Fig. 47 is taken 

 fi'om Sars, (/. c.,) for the purpose of comparison.) 



Fig. 41. A club-shaped polype, Coryne fritillaria, of 

 the natm'al size ; it consists of a so-called club- 

 shaped head, which is the original animal, or the 

 ßrst generation ; a stem which supports this head, 

 and 3-4 quadrangular bell-shaped bodies (indivi- 

 duals of the second generation) which hang on short 

 peduncles around the base of the club-shaped indi- 

 vidual. 



Fig. 42. One of the bell-shaped individuals (but very 

 httle magnified) which has become detached from 

 the " nurse." Fig. 44, a medusa-like, bell-shaped 

 individual, met with swimming free in the sea; it 

 has more than doubled its size since its separation, 

 and particular organs (generative?) have become 

 developed; of natural size. Fig. 43, the same very 

 httle magnified. Fig. 45, the same very much 

 magnified, to allow of a better insight into its struc- 

 ture. Fig. 46, some cells on the edges of the bell- 

 shaped individuals, highly magnified, in order to 

 show the vesicles, situated half in and half out of 

 them. 



Fig. 47. A young bell-shaped individual of the Cori/- 

 morpha nutans, Sars, for comparison.
