ditches in the neighbourhood of the coast. It varies greatly in 
size, and in the degree of inflation, but im no other characters. 
Broad varieties of 4. compressa strongly resemble some of its 
states, but these are always branched, though often in a very 
slight degree ; whereas L. ¢ntestinalis is invariably simple. ‘The 
compressed variety has most the look of a distinct species, and 
may be sometimes confounded with Ulva linza, under which 
name I have sometimes seen it in Herbaria; but the form of 
these plants is sufficiently different, the one being truly lanceolate, 
the other obtuse at one end, and very much attenuated at the 
other. 
I am indebted to the Rev. J. Pollexfen for a prepared specimen 
of Sea-weed, which seems to be an Huteromorpha, probably our 
F.. intestinalis, and which is used by the inhabitants of Japan as 
an ingredient in their soups, much as Macaroni is employed 
with us. ‘Thunberg, m his travels, mentions that several of the 
Ulwe and Fuci are so employed by the Japanese. In the present 
instance, the fronds have been freed of their salt, bleached, and 
tied up in cylindrical bundles, about a foot in length, and four 
inches in diameter, and, at first sight, have the look of Ismglass. - 
The specunen was given to Mr. Pollexfen by Mr. Reeves of 
Clapham, who had it from a Dutch gentleman, to whom it had 
been sent from Batavia, to which place vessels trading to Japan 
bring it with other articles. It is also said to be in use in China.
