40 CORYNLD.E. 



ing is simple and scanty. The tufts are of somewhat 

 spare and straggling habit, and have no tendency to 

 busliiness. 



The linear figure of the polypites is a v r ery marked 

 character. They are slender, of considerable length, and 

 of about equal size from one extremity to the other. 



In some specimens I have noticed that the gonophores are 

 slightly pointed above, and I believe that this peculiarity 

 will be found to distinguish the male. 



Sir John Dalyell's figure of Coryna glandulosa (Rem. 

 An. vol. ii. pi. xxi.) is an admirable representation of this 

 species. The C. sessilis (Gosse) is probably the young of 

 it. At Ilfracombe (Mr. Gosse's locality) I have frequently 

 found an unbranched and subsessile Coryne, agreeing very 

 closely with his figure, which was undistinguishablc from 

 the C. pusilla that was growing in the same pools. 



It is impossible to make much of the synonymy. The 

 C. ramosa of Alder's Catalogue I know, from correspond- 

 ence with the author, to be identical with C. pusilla. Pos- 

 sibly so is the Stipula ramosa of Sars. Alder has identi- 

 fied the Syncoryna Listerii (Van Ben.) with the present 

 form, after the examination of specimens supplied by Van 

 Beneden himself. If this decision be correct the figure 

 in the ' Mem. sur les Tubulaires ' is very inadequate. In 

 his later work Van Beneden has assigned the name to 

 a different form, which seems to be the Syncoryne 

 Sarsii. 



It were a hopeless task to attempt to clear up the confu- 

 sion that has been caused by the want of sufficiently 

 minute and careful diagnosis.
