strong light their milk-white colour betrays them. At 

 the proper season, the ambulatory zooids may be obtained 

 abundantly in the small tufts of algse that stud the bottom 

 and sides of the pools. 



Clavatella has a very definite range on the coast, not 

 descending, so far as I have observed, below the higher zone 

 of the littoral region. Its diffusion is limited, no doubt, by 

 the structure and habits of its ambulatory gouozooid.

GENERIC CHARACTER. Polypites solitary, cylindrical, ter- 

 minating above in a conical proboscis, springing from an 

 adherent base, which is clothed with a chitinous polypary ; 

 tentacles very small, capitate, covering the greater portion 

 of the body. 



Gonophores borne on coryniform processes, clustering 

 round the base of the poly pites, and containing fixed sporosacs. 



THIS curious form was first described by Otho Fabricius 

 in his 'Fauna Grcenlandica/ under the name of Lucernaria 



* This term is used to denote that there is only a single primary or ali-
