84 Praeger — The Marine Shells 



Mr. Templeton's care and accuracy are well known, but they must have been 

 derived from some passing vessel or other extraneous source ; this beautiful 

 species inhabits nowhere north of the Channel Islands.] 

 Scissurella crispata, Fleming. 



A northern species, frequenting, in Britain, chiefly the Orkney and Shetland 

 Islands. " Mouth of Belfast Bay, 27 fathoms, 2 dead specimens dredged by 

 Mr. Hyndman" — Thompson. In Hyndman's Eeports, additional specimens 

 are mentioned as having been obtained on the Turbot Bank, and a single 

 fresh shell was taken in 80 fathoms some 6 miles north of the Maidens. 

 Cyclostrema nitens, Philippi. 



Found by Jeffreys in Turbot Bank sand sent to him— Hyndman, 1858 

 Report (as Trochus (Margarita) pusillus). 

 Cyclostrema serpuloides, Montagu. 



In Turbot Bank sand, as last (sub SJcenea divisa) ; and in his 1859 Report 

 Hyndman records having dredged living examples off Larne. 

 [Margarita costulata, Mbller. 



Found by Mr. Waller in Turbot Bank sand— Hyndman. It is an arctic 

 species, whose southern limit is Iceland. Dead specimens have been dredged 

 in several Scotch localities also, which, with those from the Turbot Bank, 

 must be looked on as relics of the great ice age.] 

 Trochus helicinus, Fabrieius. 



"Living, common, on Laminaria digitata, $c." — Hyndman. Assuming 



that Margarita communis, Mont. = M. vulgaris, Leach, Thompson mentions 



the loughs of Belfast, Larne, and Strangford as localities. Hyndman dredged 



dead specimens on the Turbot Bank. 



var. fasciata. "Found by Mr. Hyndman in the North of Ireland" — 



Jeffreys. 

 Trochus Groenlandlcus, Chemnitz. 



Dredged in a dead state by Hyndman on the Turbot Bank (sub T. (Marga- 

 rita) undulatus). The specimens were determined by Jeffreys, who, how- 

 ever, remarks that they look suspiciously like fossils from a submarine post- 

 tertiary deposit in the locality. It is an arctic species, which descends as far 

 southward as the north of Scotland. 

 [Trochus cinereus, Couthouy. 



"Has been dredged by Mr. Waller on the Antrim Coast ; but it is a sub- 

 marine fossil" — Jeffreys. Hyndman abo records it, as Margarita cinerca."] 

 Trochus magrus, Linne. 



Not uncommon on the coasts of Derry, Antrim, and Down, living chiefly 

 in about 5 to 10 fathoms. 

 Trochus tumidus, Montagu. 



Belfast and Strangford Loughs, and Donaghadee — Thompson. Hyndman 

 dredged it very frequently, living in depths ranging from 10 to 100 fathoms,
