etiam in aqua stagnante, ad insulam Massko'ir, &c., Bahasise." I 

 have copied this character from the Miscrosc. Journ. i. 107. The 

 species is described and figured by M. Loven in the Ann. des Sc. 

 Natur. for March, 1841.

1. C. LACUSTRIS. Gr. J. Allman. 



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

 Hob. "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.
