244 ANTHOZOA HELIANTHOIDA. 



Hob. Dredged up among Corbulse and other inhabitants of mud, 

 in four fathoms water, in Loch Ryan, on the west coast of Scotland, 

 E. Forbes. " On the beach at Balbriggan (Ireland), after a storm, 

 in March 1843," Mrs. W. J. Hancock. 



" It is a free Actinia, about an inch and a half in length, the body 

 large above, but tapering at its posterior extremity to a point. The 

 mouth is round and rather small, surrounded by a circle of nume- 

 rous long filiform tentacula, which are nearly equal in thickness 

 throughout their lengths. The body is of a pink colour, with regu- 

 lar distant longitudinal white stripes : the tentacula are greenish, 

 with a dark line down the middle of each. It is probable the 

 animal fixes itself in mud by means of its attenuated extremity, 

 which I regard as analogous to the terminations of Virgularia and 

 Pennatula. In its anatomy it differs not from other Adinice, save 

 that its ovaries converge." E. Forbes. 



FAMILY LUCERNARIAD^:. 



This family has the same relationship to the other Helianthoida 



that Hydra has to the Hydroida. " Ovariorum dispositio Medusis 



affinior est quam Adiniis. In eundemque characterem ventriculi 



liberi pendulique defectus abit." Ehrenberg. 



33. LUCERNARIA,* Mtiller. 



CHARACTER. Body somewhat campanulate, fixed when at 

 rest by a narrow disk or stalk : mouth quadrangular, in the 

 centre of an umbrellar expansion: tentacula disposed in tufts 

 at regular distances on the peristomatous margin. 



1. L. PASCICULARIS, ''peduncle of the body produced : tufts 

 of tentacula in pairs, about a hundred in each.'" J. Fleming.

Hal. Common in Zetland, where " it is chiefly found on the leaves 

 of Fucus digitatus and F. csculentus, which grow in deep water," 

 Fleming. " Found on the coast at Donaghadee, after a strong 

 easterly gale, adhering to a fragment of Fucus serratus," Templeton. 



* From lucerna, a lamp.
