Notes on Some Species of Hydroida, principally intended 

 for Purposes of Identification. 



Clava multieomis. 



The polypites in this species are scattered, not grouped as in 

 the next. 



Clava squamata. 



Polypites in groups, clustered, gonophores in dense clusters at 

 base of tentacles. 



Clava cornea. 



Clusters of polypites much smaller than in C. squamata, gono- 

 phores smaller and less densely clustered. The two species are 

 closely allied, and Dr. T. S. Wright considered cornea a variety 

 of squamata. 



Podocoryne areolata. 



Apparently a rare species, as Hincks only records it from three 

 localities. It is easily distinguished by the sessile gonophores 

 being borne on the chitinous expansion of the stolon. 



Coryne vaginata. 



The common species of the south coast, and may be recognised 

 principally by the cup-like membranous expansion of the polypary. 

 It is essentially a rock-pool species. 



Coryne pusilla. 



In this species the tentacles are " more truly whorled than in 

 any other form of Coryne " (T. H.). The polypites are linear in 

 shape, and "of about equal size from one extremity to the other " 

 (T. H.). The only specimen I have ever had was found in some 

 material sent from Marazion. 



Eudendrium ramosum. 



The height given for this species by Hincks is "about 

 6 inches," but it appears to become dwarfed as it nears a littoral 

 habitat. 



Eudendrium insigne. 



In the absence of gonophores the specific name can only be 

 given with considerable hesitation. Hincks states its habitat
