Solen marginatum (Pulteney). 

 Occurred in the sand of the deposits rather frequently, the most so of 

 any of the larger Solens, although at present it is not an inhabitant of 

 the bay, while the other species are common. It has been dredged, how- 

 ever, in the dead state, at Bangor, near the mouth of the harbour, in 

 eight fathomR, by Mr. Patterson. 



Solen emu (Linneus). 



The variety Magna was present, and was represented in the sandy 

 deposits by one or two poor examples, while Solen siliqua, which is ex- 

 tremely abundant in the bay, was not met with at all. Both the typical 

 form of Ensis, and the variety Magna, occur in the living state in the 

 harbour. 



Solen pelluctdus (Pennant). 



Was found rather locally in some numbers in the sand, and was 

 also embedded in the blue clay, where there appeared to be no sand, 

 contrary to what we should expect. The length of a good specimen 

 was an inch and a half; its greatest breadth three-eighths of an inch. 

 It is dredged commonly enough in the bay. 



Solen siliqua (Linneus). 



Since the proof-sheets of the foregoing passed my hands, I met with 

 several fragments of this species in a large heap of the sandy mud which 

 has been raised by the steam-dredges from the bed of the present chan- 

 nel near the light-house. At the same time, during a search of one hour, 

 the number of species I observed amounted to no less than sixty-two. 



Ceratuolen legumen (Linneus). 

 A single valve of this species was found by Mr. Millen in the light- 

 house deposits. It has never been obtained before from the bay, either 

 living or dead. 



Solecurtus coarctatus (Gmelin). 

 A single rather fine example of this scarce species was met with in 

 the clay by E. Aikin, Esq., of Dublin. It has not been discovered in 

 the bay as a living species ; but it has been taken in some of the 

 neighbouring estuaries, Larne Bay especially.
