I believe, the heiglit of forty feet at Carrickfergus, thirty feet at "White 

 Abbey, and twenty feet at Greencastle (-vrhich the author indicates 

 are heights above high water) are exaggerated ; so far as I am aware, 

 the most elevated raised beach in the district is that of Larne, which 

 rises to about twenty-two feet above high water. 



Mr. "W. A. Traill has noted^ a few fossils of Antrim raised 

 beaches : — 



Cra.igvt:llen, three miles S.-E. of Glenarm, at the mouth of the 

 stream, four to eight feet above high water. — Venus ^' Itncta or 

 obsoleta,^' Patella vidgata, Helcion pellucidum var. Icevis, Littorina 

 ohtusata, L. litorea, Troclius sp. 



CLOSEBrEX Bat, five miles S.-E. of Glenarm, in the townland of 

 Fourscore, four to eight feet above high-water mark. — Pectuncuhis 

 glycymeris, Cyprina islandica, Patella vulgata, Selcion j^ellucidum var. 

 lavis, Littorina ohtusata, L. litorea^ Irochus cinerareus. 



Lastly, we have the famous raised beach of Portrush, discovered 

 by James Smith of Jordan-hill, and first described by Portlock^: "The 

 remarkable accumulation of shells, mixed with sand, which occupies a 

 bowl-shaped hollow, about ten feet above the sea on the north side of 

 Portrush, and open in that direction to the sea." Portlock gives a 

 list of the fossils, eighty-eight ia number, supplied by Smith, and 

 adds to these the coral Caryopliyllia Smithii. Smith's own comment 

 is worth quoting: — "This shelly deposit seems to have been a sheltered 

 bay into which the shells have been drifted, with a small admixture 

 of land-shells, washed down by floods ; none of the bivalves have both 

 valves together, but they have been but little injured by the action of 

 the sea ; I have never met with such a variety in so small a space, 

 either in recent or ancient beds." 



Grainger^ gives a list of fifty-four species obtained by him in this 

 bed, adding a few species to its fauna ; Stirrup includes in his Paper 

 a short list of its fossils ; and Alfred Bell,* from material suppKed by 

 local correspondents, has added others, bringing up the total fauna to 

 no less than 126 species and varieties. It is not necessary here to 

 reproduce this long list, but attention is drawn to the occurrence of 

 the following species : — Lima Mans, Venus verrucosa, Venerupis irics, 

 Rissoa albella, R. costulata, Odostomia excavata, Adeorbis subcarinatus,
