SOME ALG^B FROM THE ANTRIM COAST. 



BY HENRY II ANNA, M.A., B.SC. 

 [Collected for the R.I.A. Flora and Fauna Committee.] 



Thk following notes contain some of the more interesting 

 results on the seaweeds collected on the coast of Co. Antrim. 

 Excursions to various points on the coast were made, where 

 suitable conditions were likely to exist for shore-collecting or 

 dredging, such as the Gobbins, Larne Harbour, Murlough 

 Bay, Colliery Bay, Torr Head, Portrush, and the Giant's 

 Causeway, in addition to part of Belfast L,ough. It was not 

 found possible to visit Cushendall, Cushendun, or Glenarm, 

 including Canilough, places I should have liked very much to 

 explore, but this would have exceeded the limits of the time 

 at my disposal. 



On July 4th, 1898, and on a subsequent occasion, the Gobbins 

 were visited for to carry out shore-hunting : here I found a 

 fine specimen of Ectocarpus brachiatus, Harv., (- Stictyosiphon 

 Giiffithsia?ia, Holm, et Batt.), growing on a very young 

 specimen of Fucus scrratus, on an exposed part of the coast. 

 Dr. Bornet, to whom I am greatly indebted for kindly 

 examining it, referred it to Ectocarpus brae hiatus, Harv., similar 

 to that seut out in Mrs. Wyatt's Alg. Danm., No. 187. The 

 usual habitat for this plant is Rhodymoiia palmata. 



Dredging was carried on in and outside L,arne Harbour on 

 three different occasions towards the end of July, and on the 

 25th September. Numerous Nitophylla were dredged, the 

 principal being N. taccratum, Hillier ; also a small scrap of 

 Bonnemaisonia asparagoides, and some forms of Lithotha?n?ua. 

 The latter were forwarded to Dr. M. Foslie, who kindly 

 undertook their examination, one of which he makes the type 

 of a new variety of Lithophyllum calcarcum—i. cunana, Fosl. in 

 a recent number of the Sclskabs S k rift cr (no. 6, 1898). 



The first week in August was spent at Murlough Bay, and 

 neighbouring localities were examined, such as Colliery Bay 

 and Torr Head. Mr. E. M. Holmes accompanied me on this 

 occasion, and his assistance was invaluable.
