North Sea Dredging. — By John Leckenby, F.L.S., F.G.S., 

 and J. T. Marshall. — Annals and Mag. Nat. Hist., Dec. 1875, 

 series IV, vol. xvi, pp. 390 — 4. 



A lengthy list of species and varieties, the result of three 

 dredging cruises to the Dogger bank. All the species enumerated 

 were obtained between 20 and 90 miles from land, and at depths 

 of from 7 to 50 fathoms. Fifty-seven species and twenty-one var- 

 ieties of bivalves, and 63 species and 28 varieties of univalves are 

 recorded as having been obtained. 



Two varieties are described as new by Mr. Marshall, viz : — 

 Nucula nitida, var. turgida. — "Shell more triangular, and beaks 



more swollen. Corresponding with the deep water varieties 



of N. nucleus and N. tenuis. 

 Natica catena, var. Leckenbyi. — "Shell brown, without any colored 



markings. It resembles N. sordida, but is thinner and more 



globose. Searles Wood's JV. catena from the Coralline Crag is 



similar to this. Obtained in 10 fathoms." 



From a mass of Filograna complexa, an Area was obtained, 

 which Dr. Jeffreys refers to Area imbricata, Poli, though from the 

 absence of the notched inside margin, Mr. Leckenby thinks they 

 may with more propriety be. referred to Area nodulosa, Mull. 



The animal of Natica Grcenlandica, Beck, is described from 

 specimens found in company with Scalaria Trevclyana, Leach. 



The occurrence of the four varieties of Astarte sulcata, Da 

 Costa (paucieostata, minor, inerassata, and multicostata) is interest- 

 ing, as they have been previously recorded from the Shetland Seas 

 only. 



Trochus occidentalis, Mighels, and Tectura testudinalis, Mull., 

 are also noted, the nearest recorded locality of the former being
