II. SKKTl'LAKIXA. 



Family. — Sertulariada. 



5. U.u.i:< ii m. Oken. 



The name is from Hahr, i herring; and it is called the Jierring-bone 



coralline 



1. Haleeium hah'i-lnum. I have not fouml this on the coast of Ayr- 

 shire, but I havo repeatedly dredged it in Arran. 



2. II. muricatum. I have not found this on the Ayrshire coast; but 

 I have got it on oysters from Stranraer. 



6. Sertularia. Linnaeus. 



1. Sertularia polyzonias. This is not uncommon with us, and it is 

 still more common at Troon. It is almost always found on Halidrys 

 s'(!i>juosa. 



2. S. rugosa. This is very rare with us. I have found it only once 

 or twice on seaweeds. 



3. S. pumila. Very common here, and all along the coast, and in 

 Arran. It is generally on the larger seaweeds, such as Fucus serratus, 

 vesiculosus, and nodosus. The finest and largest specimens, however, I 

 have ever seen of it, were between Leith and Portobello, on young 

 plants of Laminarla saccharina. 



4. Sertularia abietina. I have at times got specimens of this, though 

 rarely, amongst rejectamenta, on the shores of Ayrshire. It is found 

 abundantly in Lochryan, at Port- Patrick, and at Little Ross Island, near 

 Kirkcudbright. 



4. S. filkula. This is rare with us. It is at times, however, found 

 on seaweeds, and about the roots of Laminaria digitata. 



5. S. operculata. This is not uncommon. It is found on the stout 

 stems of Laminaria digitata. I once found it intermingled with the 

 stems of Furccllaria fastigiata. It is seldom three inches in height ; 

 whereas I have seen specimens from Lough Swilly, measuring upwards 

 of four in- 



We are not rich in Sertularia, as we have only five of the seventeen 

 that have beon observe- 1. 



7 Am nnularia. Lamarck. 



The name, from antennula, a diminutive of antenna, a feeler. 



1. Antennularia ramosa. I have not found this more than once on the 

 coast of Ayrshire ; but I have got it in the Kyles of Bute, and off Cum- 

 in i es, and very fine specimens, by dredging in Arran, and also from 

 fishermen. 



It has been made a question whether thi3 be more than a variety of 

 Antennularia antennina, and there are many of high authority on each 

 side of the question. I am cti join the minority, and to say that
