Verrill, JVotes o?i HacUata. 471 



This genus is allied to AathopUxira Diich. and Mich., but the latter 

 is re}>resented as having equal tentacles, and the uppermost tubercles 

 are subdivided and sub-tentaculiform. It resembles Sunodes, but in 

 the latter the walls are imperforate and the inner tentacles are largest.

Column low, Ijroad, subcylindrical, often dilated in the middle, and 

 covered with regular vertical lines of prominent, rounded tubercles, 

 which are obsolete below, the upper ones larger and forming a row 

 around the margin of the disk. Tentacles in three series, stout, sub- 

 ulate, the inner ones '5 inch, the outer ones 1 inch in length. Disk 

 radiated ; mouth with four prominent lobes. 



Column yellowish green ; the tubercles dark sap-green, the green 

 line extending to the base, though the tubercles are obsolete below.

" This species occurs buiied to the tentacles in sand, and also at- 

 tached to pebbles or shells two or three inches below the surface. 

 On contracting, water spurts from various small lateral orifices, as 

 from a watering-pot," — C. Pickering.

"Body sub- verrucose, yellowish green. Tentacles numerous, elon- 

 gated, fusifoi'm, flattened below, copper-gi-een, with small, transverse, 

 yellow spots." 



Sitcha Island, — Brandt. 



This species may prove identical with the preceding, and in that 

 case would have priority. There are no certain indications of its gen- 

 eric affinities, and I have placed it here mainly on account of its gen- 

 eral resemblance to M artetnisia. 



Cladactis Yerrill, gen. nov. 



Column firm in texture, low, broad, crowdedly covered with ele- 

 vated, sub-tentaculiform tubercles or papillae, which have round, in-
