PROF. THOMSON AND MR. McQUEKN — REPORT ON THE ALCYONARIANS, 11.") 



The spicuk's of Mopsea are described as " finely-spined. unsymmetrical 

 scales, slightl)' notched at the edge ; the spicules of Clathraria are spiny and 

 tuberculate clubs, warty double-clubs, and spindles with very minute warts." 

 For these ami other reasons we think that Clathraria may be usefully 

 retained as a distinct genus.
