 Hah. On old shells and stones in deep water, common. Common 

 on oyster shells in the Frith of Forth, Prof. Jameson. Vicinity of 

 Stockton-on-Tees, J. Hogg, Esq. Found on the shore of Belfast 

 Lough, Mr Templeton. Cork Harbour, J. V. Thompson. Coasts 

 of N. Durham aud Berwickshire. 



Polypidom from 4 to 6 inches high, fixed by numerous fibres " ir- 

 regularly matted together like apiece of sponge," of an earthy-brown 

 colour, stiff, brittle when dry, irregularly branched, the stem and prin- 

 cipal branches composite, tapered upwards, pinnate ; the pinnae alter- 

 nate, patent. Cells alternate, tubular, bi-articulate, the aperture 

 even. Vesicles unilateral, scattered, of an oval shape " with a tube 

 arising from the pedicle, and passing up on one side to a little above 



the top of each," Ellis Young specimens are often partially 



coloured a bright yellow, dependent apparently on the colour of the in- 

 terior pulp. When the specimen is recent and clean the cells are seen 

 to be divided by one or two wrinkles or joints, but in general they 

 are obscurely marked. 



2. T. Beanii, vesicles calceoliform, the aperture suhcentral^ 



shortly tuhulous. Mr William Bean.*

 Hah. " Near Scarborough, in deep water, very rare," Mr Bean. 

 Polypidom 1 1 inch high, irregularly branched, the branches alternate, 

 spreading, the principal composed of many parallel tubes, the ulti- 

 mate of a single tube, with a joint between each cell, which is small, 



that any genus of plants has been dedicated to his memory, — an honour of which 

 he seems not unworthy. He must not be confounded with another James New- 

 ton, author of a " Compleat Herbal," Lond. 1752. 



"■ Mr B. of Scarborough, well known to naturalists generally by his numerous 

 discoveries in British Zoology, recent and fossil. To some of his new species 

 the trivial name fabalis has been applied, but the justice of such a conceit or 

 puzzle is questionable, since it veils the discoverer's name from those who are 

 not good guessers.
