78 ZOOPHYTOLOGY. 



From the former, which, with the greatest deference to 

 Mr. Hincks^ opinion, I am disposed to regard simply as an 

 unarmed variety of M. Flemingii, M. irregularis differs 

 principally in the more oval or rounded shape, and more 

 irregular disposition, and inequality in size of the cells. 

 From worn specimens of M. Lacroixii it would be difficult 

 to distinguish M. irregularis, excepting by the total absence 

 of any marginal spines and of any vestige of avicularia; 

 whilst between M. irregularis and M. simplex, D'Orbigny, 

 I am unable to perceive any important diversity.

A species of Eschara occurs in the Egean Sea (of which I 

 have specimens collected by E. Forbes), having the polyzoary 

 constituted of slender, subcylindrical branches, and the cells 

 produced in a tubular form above, and which consequently in 

 some respects corresponds with the present species, but on
