Cordylophora lacustris, Allman in Ann. Nat. Hist. xiii. 330. 



Hah. — "The locality of the zoophyte is the dock of the Grand Canal, 

 Dublin. Into this ships have access from the sea by means of a 

 lock, but the dock is quite free from any admixture of sea-water ; in 

 fact, did any doubt exist as to the genuine fresh- water habitat of the 



zoophyte, the circumstance of my 

 having kept it alive for nearly a fort- 

 night in a glass of fresh water not 

 taken from the dock, would be suffi- 

 cient to dispel them. It grew upon 

 the bottom of an old submersed canal 

 boat, but as yet I have obtained it in 

 but very small quantity." — Allman. 



" Polypidom horny, rooted by a 

 creeping tubular fibre, alternately 

 branched, branches cylindrical. Po- 

 lypes developed at the extremities of 

 the branches (Fig. 5), and consisting 

 of an ovoid body, prolonged ante- 

 riorly into a conical projection, which 

 bears the mouth at its extremity, and 

 behind which the body of the polype 

 is furnished with scattered filiform 

 tentacula." — G. J. Allman.
