bunches : each frond as thick as whipcord ; forked once 

 and again, and tapering at the tips : there was plenty of 

 it among the Fuci, on the Ardrossan rocks.

The Dumontia filiformis, with its thread shaped frond 

 and simple branches, and the rose-coloured palmate 

 Halymenia Legulata, we did not find. 



The Kallymenia reniformis is a lovely weed ; its name 

 signifies beautiful membrane; the expanded frond is 

 roundish and stretched at the margin ; the specimen 

 given to me was about three inches in height. The tide 

 pools furnished us with the Tridcea Edulis, or Sweet 

 Dulse : the frond is egg shaped, but tapering toward 

 the base ; it is dark red, and of a leathery texture. This 

 species used to be much eaten both by human beings and 

 cattle ; and Harvey says it is still used as an article of 

 food by the poor, either raw or fried. 



In some of the shallow pools the little Catenalla 

 opunita was growing under the shelter of large weeds ; 

 it looked like young plants of Chylocladia artieulata, 

 the branches being contracted at the base ; the whole 

 height of the fronds was but half an inch, and the 

 colour was a brownish purple. Its name means little 



chain* 



The Cruoria pellita, or Blood-stain, succeeds the Cate- 

 nella in order ; the glazed brownish stains upon the 

 stems of the Laminaria digitata, which we had found at 

 Oban, were plants of this weed. 



Xo specimens of Naccaria, Gloioisphonia, Dudresnaia, 

 or Crouania, came in our way ; most of these weeds are 

 rare, or confined to the south coast.
