92 Praeger — The Marine Shells 



Scalaria Trevelyana, Leach. 



"Mr. Hyndman possesses a specimen from Magilligan" — Thompson; a 

 specimen from thence, out of Mr. Thompson's collection, is in the Belfast 

 Museum. It does not appear to have heen taken elsewhere in the province. 

 Scalaria clathratula, Adams. 



" Bundoran, Mrs. Hancock " —Thompson ; specimens from thence are in 

 the Belfast Museum. Hyndman dredged dead shells on several occasions, in 

 the vicinity of the Turbot Bank. 

 [Acirsa borealis, Beck. 



" Dead, in Turbot Bank sand, Mr. Waller, 1857. Described by him in the 

 " Transactions of the Royal Dublin Society," and provisionally named 

 Turritella Hibernica' n — Hyndman (sub Scalaria Eschrichti). " Dredged in 

 18-20 f. off the coast of Antrim, by Mr. Hyndman, Mr. "Waller, and myself. 

 This species has not been found living south of Iceland " — Jeffreys.] 

 Aclis unlca, Montagu. 



"Bundoran, Mrs. Hancock. Deep water, Belfast Bay, Mr. Hyndman" 

 —Thompson (Chemnitzia unica). Turbot Bank, dead, very rare — Hyndman. 

 It is a littoral species. 

 Aclis ascaris, Turton. 



"Bundoran (Mrs. Hancock, fide Thompson) "—Jeffreys. 

 Aclis supranitida, 8. Wood. 



" It has been collected at Bundoran by Mrs. Hancock" — Thompson (sub 

 Chemnitzia glabra). Hyndman dredged dead shells occasionally in the 

 vicinity of the Turbot ^ank. 

 Aclis Oulsonse, Clark. 



In Turbot Bank sand, determined by Mr. Jeffreys— Hyndman (Jeffreysia 

 Gulsonce). Specimens from the Turbot Bank are in the Belfast Museum. 



var. tenuicula. "Lough Strangford (Waller) " — Jeffreys. 



Genus Odostomia, Fleming. 



This, the largest and perhaps the most complicated genus of British shells, 

 has by no means been worked out in our district. With the assistance of 

 that eminent conchologist, Mr. Jeffreys, Hyndman was enabled to publish 

 very full lists of the Odostomice of the Turbot Bank, and of the 34 British 

 species, no less than 21 are recorded from this vicinity, all in a dead state ; 

 but beyond this, there is a paucity of information concerning them. Their 

 minute shells are easily overlooked, and it is only with the aid of the micro- 

 scope that the exquisite sculpture which characterises many of the species, 

 may be seen with advantage. In the absence of records of any of the 

 following species having been taken alive, I have omitted noting "dead" 

 after each station. 



Odostomia nivosa, Montagu. 



" Turbot Bank sand Mr. Jeffreys " — Hyndman (sub 0. cylindrica).
