latter identification is certain ; since MacGilliyray's figures, both of the unfertile branches and 

 of the ovicell, show a considerable resemblance to C. radians. It is just possible, therefore, 

 that Crisina may have ovicells of the C. radians type indifferently on the frontal or the basal 

 surface of the branch .
