BRITISH ZOOPHYTES. 95 



Capsularia lacerafca {Gray), Laomeclea lacerata {T. H., 

 T. 8. W., Aid., P. H. G., McA.), Wrightia lacerata 

 {Ag.), Calycella lacerata {xLll.) . 



Hab. : St. Ives, Exmouth, llfracombe, Isle of Man, 

 Filey, Oh^niHinchs), Berwick (G.J.), Northumberland 

 (Aid.), Firth of Forth (T. S. W.), St. Andrew's {Reid), 

 North of Ireland (Thomson). Height from \ — Ijin. 



In this species the upper part of the calycle is divided 

 into six deep lanceolate segments, which collapse and 

 form an acute apex or roof. The tentacula are very 

 extensile. Prof. Reid states that they can be extended 

 twice the length of the cell. The stem is annulated 

 throughout. 



FAMILY III. LEPTOSCYPHID^. 



Calycles ovato-conic. Polyiiites cylindrical, ivith a 

 conical proboscis. Generative elements produced in the 

 walls of the mamihrium. Lithocysts wanting. — T. H. 



(xENUS Leptoscyphus, Allman. (^eirro'i, delicate, 

 (TKiJ^jroi;, a cup.) 



Stem simple or branching, attached by a thread-like 

 stolon. Calycles with an operculum composed of diver- 

 gent segments. Polyjntes cylindrical, with a conical 

 proboscis. Reproduction by free medusiform zooids. — 

 T. H. 



L. TENUIS, All. 



Laomedea tenuis (AIL, McA.). 



The medusiform zooid of the species is identical with 

 the Lizzia of Forbes. This is the only species of the 

 Thecaphora in which the generative elements are 

 produced in the walls of the manubrium of the gono- 

 zooid.
