240 Kkv. Mn. Landsborough's List of Zoophytes. 



Family. — Escharidce. 



13. Cellularia. Pallas. 



1. Cellularia ciliata. Very beautiful, but very rare here. This, also, 

 I found in great beauty on the shore opposite to Fort-George. 



2. C. reptans. Very common hero. It is most frequently found on 

 Halidrys siliquosa. The finest and largest specimens I have got were at 

 Troon. It is very brittle when dry. 



3. C. plumosa. This is not found here. I think I dredged a little of 

 it in Arran. It is found in Lochryan on oyster shells. It was formerly 

 Acamarchis plumosa. 



14. Flustra. Linnaeus. 



The name is from the Saxon word flustrian, to weave. 



1. Flustra foliacea. Common as this sea-mat is in many places, it is 

 very rarely that the smallest fragment of it is found on the shore here. I 

 have a specimen which was dredged in Lamlash bay some months ago, and 

 it has still a little of that sweet fragrance, like heliotrope, which it had 

 when fresh. I think this flavour is different at different places. At Leith, 

 where it is abundant, it seemed to me to have the flavour of Verbena 

 triphylla. 



I never saw even the smallest portion of Flustra truncata on our western 

 shores, though it seems so nearly allied to F. foliacea. Dr. Johnston says 

 that " it is very common on the shores of Scotland." The western shores 

 must be excepted. 



2. F. membranacea. This is very common on large seaweeds, espe- 

 cially Laminaria digitata. I have seen a web of this beautiful lace six 

 feet in length by eight inches in breadth. The polypes in this one colony 

 were almost equal to the population of Scotland. At times the Flustra 

 is roughened by little compressed linear projections, rising about a 

 quarter of an inch above the surface, the use of which I did not know ; 

 and I got it once on one of the smaller algae, where, for want of room 

 to expand itself on the alga, it mounted up, and was, to a certain extent, 

 free. 



3. F. coriacea. This I have not seen, but it has been dredged adher- 

 ing to shells, by Mr. Hyndman, off Sana. 



4. F. ? lineata. Very common with us, and especially on Laminaria 

 saccharina. 1 have at times been disposed to think that this was an im- 

 perfect state of Leparalia nitida. The rigid varieties with the spines met, 

 come very near it. Mr. Peach thinks it a good species. 



15. Salicornia. Cuvier. 



1. Salicornia farciminoides. This is a very beautiful zoophyte. The 

 first specimens I saw of it were from Lochryan and Portpatrick. I never 

 met with it on the Ayrshire coast. A month or two ago, I got a speci- 

 men of it that had been dredged by a fisherman off Arran.
