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 subcentral , 
shortly tubulous. Mr William Bean. #

Hab. “ Near Scarborough, in deep water, very rare,” Mr Bean . 
Polypidom 1 J 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 notunworthy. 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.
