Praeger — The Marine Shells 



the trouhles attending dredging on such ground, at such a depth, have heen 

 rewarded with living examples of Argiope cistellula, A. capsula, Propilidium 

 ancy chides, and other deep-sea treasures.

 and corresponding part of the Irish Channel," by George Dickie, M.D., 

 Professor of Natural History, Queen's College, Belfast, in the British Associa-

Then follow lists of the Testacea of the open channel opposite the entrance 

 of the Lough, divided into zones according to the distance from shore. 



V. "British Conchology," by J. Gwyn Jeffreys, F.R.S., &c, 1863-9. 

 This work contains, besides repetitious of many of Thompson's, Dickie's, and 

 Hyndman's records, some notes of species obtained by the author, and also by 

 Mr. Waller and Mr. Adair, on the North of Ireland coasts ; those notes will be 

 found under the respective species. 



There are earlier works which contain references to North of Ireland 

 Mollusca, but all reliable records of any importance are to be found repeated in 

 the books cited above. During the long period that has elapsed since the publi- 

 cation of even the latest of these, though a good deal of dredging has been done 

 by local scientists, very little has been added to the knowledge of our Marine 

 Shells, attention having been chiefly concentrated on the interesting Microzoa 

 which the earlier Naturalists had left almost untouched. Indeed, the only 

 additional matter of which I have been able to avail myself is a few manuscript 

 notes by Mr. S. A. Stewart, F.B.S.E., and the same by the present writer, 

 while an examination of the shells contained in the cabinets of Mr. William 

 Swanston, F.G.S., of Belfast, and Miss Richardson, of Portrush (to both of 

 whom my best thanks are due), and of those in the local collection in the 

 Belfast Museum, has yielded some additional stations for species.
