At Station 15, but especially at 19, single valves were 

 abundant, but only a few small living specimens were found. 

 This little bivalve seems to be destroyed wholesale by a 

 univalve enemy, for nearly half of the valves found had been 

 pierced by a Gasteropod, perhaps by the smaller Naticce 

 (Alderi, Montagui, and affinis) which are abundant in the 

 same locality. 

 32. Crenella decussata, (Mont.) Only a single living speci- 

 men occurred, south side of Kors Fiord, in 20 — 30 fathoms.

Throughout the district in 20? — 400 fathoms on a fine 

 mud bottom. In "British Conchology" Jeffreys mistakingly 

 gave Malm's species as a variety of muleus and recorded it 

 from Shetland; he has more recently become acquainted 

 with the true N. himidula (not yet found in our seas), and 

 regards it as a good species {vide "Norwegian Mollusca," 

 Ann. Nat. Hist., June 1870, p. 3, separate copy).

At Station 16, near the entrance of Fane Fiord, in 50 — 

 120 fathoms were dredged two dead valves. These corres- 

 sponded so closely in appearance with the condition of the
