No. 2.] MATTHEW — POST-PLIOCENE MOLLUSCA. 107 



may be mentioned bones of a seal and a whale, teeth of a large 

 mammal, various crustaceans, echinoids, worms, corals and sea 

 weeds, besides the molluscs which it is my purpose now to 

 describe. 



In the following list I have noted the bathymetric and geogra- 

 phical range of most of the species named, and added further 

 remarks upon any peculiarities which seemed worthy of mention. 

 The zones of depth referred to in this catalogue are Littoral — 

 the space between high and low water marks ; Laminar ian — 

 from low water to a depth of fifteen fathoms ; Coralline — the 

 depth from fifteen to fifty fathoms. For the vertical range of 

 species given in this paper I am in most cases indebted to Dr. 

 Stimpson's catalogue, "Shells of New England." The B.iy 

 Chaleur shells were collected by Mr. Robt. Chalmers. 



The localities indie ited by letters are — R. C, River Charlo, 

 B. P., Black Point, R. B., River Benjamin, T. R., Tatagouche 

 River— all on Bay Chaleur ; St. A., St. Andrews and Oak Bay, 

 St. Gr., St. George, St. J., St. John, in the Bay of Fundy. 



Neptunea tornata, Gould. — Recent, Arctic seas to the Gulf of 

 St. Lawrence. — Fossil R. C, R. B., St. A. Not common either 

 in the Bay Chaleur or Bay of Fundy deposits. Another speiies 

 •of this genus N. decemcostuta, which though now living on the 

 coast has a more southerly range than N. tornata, has not been 

 found in the Leda clay further north than Brunswick, Maine. 



Sipho Kroyeri, Moller. — Recent, Arctic seas to Gulf of St. 

 Lawrence. — Fossil, R. C, B. P., St. A. ? Rare in these places. 



Buccinum undatum, Linn. — Recent, Greenland to Massachu- 

 setts Bay. — Laminarian to Coralline. — Fossil, R.C., R. B., St. J., 

 St. A. In the deposits on the B iy of Fundy this species is much 

 more common than the succeeding buccina ; but on Bay Chaleur 

 .shells of the other species are equally numerous. 



B. tenue, Gray. — Recent, Arctic seas to the Gulf of St. Law- 

 rence. — Fossil, B. P., R. C, St. J. Much less abundant than B. 

 undatum. 



B. glaciale, Linn. — Recent, Greenland to Gulf of St. Law- 

 rence. — Fossil, B. P. Rather scarce. 



B. Groenlaridicum, Chemn ? — Recent, Greenland. — Fossil, T. 

 R. I am not sure that this species is correctly referred, the 

 specimen (sent to me by Rev. C. H. Paisley) is more ventricose 

 than that figured by Dr. Dawson ; the upper part of the whorls 

 is also less tumid.
