profusely on the bottom of a vessel which had been layi 0 .-’ 
in Fowey harbour for some months. This species was fi r f 
described by Dr. Johnston and figured by his lady, and * 
honour of her is called “ Catherina,”

Hab. “ On the back of the spider crab, and on a slab 1 
limestone.” Goran, Mr. Peach. 
This beautiful coralline is of rare occurrence in our^sea* 
I have never procured a specimen myself, but Mr. 1 ea ^(}’ 
has kindly favoured me with three from deep wale* j 
Goran, one of which is remarkably fine, measuring six * 
half inches in height; from these 1 have taken the folio * 11 f 
description. The polypidom is stout, erect, and of a y c 
lowish horn colour. The trunk is stout, composed of o> 3 ^ 
sub-parallel tubes agglutinated together; marked on the ba® 
at intervals of from a quarter to one inch, with protuberant^ 
as if it was composed of internodes, which overlapped 0,1 j 
other at their extremities; the overlapping parts are un*^ 
by transverse fibres, which do not appear to be parts ot ^ 
same tubes which compose the stem. In recent spec' 31 , 
the tubes are not so apparent as in the dried state. ’ ^ 
dried the stem is furrowed longitudinally, and in the furro^ 
thickly marked with minute round orifices ; similar > D . ^ 
pearance and perhaps in function, to the stomata of do* 1 . 
plants. The pinnae are confined to the upper portions o . 
stem, the lower, for one third or two thirds of its 
being bare; they are divided at short intervals into j 0 .^, 
are opposite, but from their frequently leaning all to one .^pif 
they appear to be unilateral. The cells are deeply tu 
closely arranged one on each internode and attached to^j 
pinnee throughout their whole length ; they are 
and placed on the inferior margins of the pinnae in the a 
of a curved spine. The apertures of the cells are p at
