VALKERIA ITVA. 553 



The polypide affords a good illustration of tlie Campy- 

 lonemidan structure (woodcut^ fig. 33) . It is interesting 

 to watch it issuing from its cell ; at such a time the pecu- 

 liarity in the tentacular wreath is very apparent. When 

 the pencil of tentacles is risings as soon as it has reached 

 a certain point the two bent arms spring out^ one at each 

 side^ the rest continuing straight and folded together 

 until the whole bell expands. V. uva, especially in its 

 humbler form, is one of the commonest of our lit- 

 toral species, and may be readily obtained on the 

 Corallina in rock-pools, over which it creeps in great 

 abundance. 



Habitat. On various Fuci, Corallina, Sertularia pu- 

 mila, &c., and occasionally on shells, between tide-marks 

 and in shallow water; rarely in deep water (form 

 cuscuta) .
