232 Marine Algm of Berwich-on-Tweed. 



Dr. Farlow in -his " Marine Algae of New England," says that 

 (U.athrocysbis roseo-perxicina, which is not uncommon at. Berwick, is "also 

 found on codfish in the Gloucester market, causing what is known as the 

 ' red u'sh.' " Tn connection with this I would call attention to a curious 

 passage in Kay's Synopsis Ed., I. p. 3, qnoted by Johnston (Fl. Berwk. n. p. 

 24-7), " Bambergas Northumbriae cum essem, narrarunt mihi piscatores 

 speciem quandam Algae tinctoriae in mari oram alluente copiose provenii'u, 

 quae piscium etiam transnatantium tergora colore suo inficiat. Plantain 

 ipsam non vidimus, sed ex eoriim relatione Algae tinctoriae J. B. affinem 

 esse snspicabamur." May not the fishermen of Hamburgh have met with 

 some " red fish," and have hastily concluded that they had been "dyed" 

 in the manner described above P

Hob. On Sphacelaria radic.ans, Gladophorce, and other small Algae in 



shallow puddles near high water mark. Aug. — Dec. Rare. 



Berwick Bay, Greenses. 



A small species composed of bluish-green oval cells, arranged 

 in several layers so as to form a solid mass. Cells about -006 

 mm. by -008 or -009 mm. 



Note. — In the caves north of Dodd's Well and elsewhere along the 

 coast, the walls are covered from a little below high water mark to con- 

 siderably above if with a curious Alga which seems to belong to Borzi's 

 ^iins Hirrnotila, but as yet I have been unable to find any form of 

 fructification. The plant forms strata of considerable thickness of a 

 yellow or yellow-green colour, often growing; over other Algae such as 

 Calothrim scopulorum and Rivularia Biaaolettiana. It is composed of 

 roundish, oval, or oblong cells filled with a granular endochrome, and 

 surrounded by a thick cell wall. The dimensions of the vegetative cells 

 are the same as those of Hormotila mucigena (Borzi Studi Algologici, p. 

 9.t, t. vni.) ; bur until the fructification has been seen, it is impossible to 

 determine with certainty even the genus to which this puzzling plant 

 belongs. With ns the Alga, whatever it may tarn out to be, is far from 

 uncommon, and where it does occur is always found in abundance.
