78 Praeger — The Marine Shells 



Black Head, broken, but with ligament fresh, so that it is probably still living" 

 — Hyndman. Dickie took it three times in Strangford Lough, but dead in 

 each case. 

 Thracla distorta, Montagu. 



"In limestone near Belfast, with Saxicava, Mr. Grainger" — Thompson. 

 The only other note is a repetition by Hyndman of this record. 

 Corbula gibba, Olivi. 



" Strangford Lough is the best locality known to me for this species, in 

 some parts of which it is common on muddy ground, at a depth of about from 

 4 to 10 fathoms" — Thompson {sub C. striata). Living in 12-20 fathoms off 

 Belfast Lough, and in 1-90 fathoms off Larne and the Maidens — Hyndman. 

 The results of Dickie's explorations in Strangford Lough amply confirm 

 Thompson' s note, as this shell was found in abundance, alive, at every station, 

 4 to 25 fathoms. Living, common, 8-10 fathoms, Belfast Bay — Mr. S. A. 

 Stewart. 

 IVEya arenaria, Linne. 



A common littoral species, living in abundance in muddy estuaries. I have 

 seen specimens of unusual size (3x5 inches) dug on the Holy wood Bank for 

 bait, and at Cultra have found small distorted individuals inhabiting the for- 

 saken burrows of Pholades. Locally called " cockabrillion " or " cockle- 

 brillion." 

 Mya truneata, Linne. 



With the last, but frequenting more the open sea. 

 var. abbreviata was dredged by Hyndman and Jeffreys living in 80 fathoms 



off the Antrim coast, some 1 miles from land. 

 Mya Bing-bami, Turton. 



Turbot Bank, living, rare — Hyndman (sub Sphcenia Binghami). Occa- 

 sionally met with in a dead state. 

 Saxicava rugosa, Linne. 



Burrowing in limestone and old shells, or free. " Common around the coast 



on the North and East" — Thompson. Living commonly in from to 30 



fathoms in the waters explored by Dickie and Hyndman ; the latter dredged 



living examples in 70-90 fathoms near the Maiden Rocks. 



var. arctica. "With the typical form, but not so abundant, and inhabiting 



rather deeper water (S. arctica). 

 Venerupis Xrus, Linne. 



In Thompson's collection in the Belfast Museum, there are specimens of 

 this shell labelled "Bundoran, Co. Donegal" ; in the 4th volume of the 

 " Natural History of Ireland" there is no mention of its occurrence there. 

 Pbolas dactylus, Linne. 



Burrowing in sandstone, marl, and hard clay, between high and low water 

 mark, on both sides of Belfast Lough ; Carrickfergus, Greenisland, and Cultra 

 may be mentioned as localities where it may be taken alive,
