OF LABRADOR AND MAINE. 233 



ovate; canal, long, narrow, oblique, and not gradually widening towards the aperture. It 

 has much fewer ribs than B. americana, there being thirteen on the lower whorl, where in 

 B. americana are eighteen. Length .18 ; breadth .11 inch. 



Bela americana Packard. (Fusus iurricidus Gould, Invert. Mass. Bela scalar is Packard. Can. 

 Nat. and Geol. 1863,— not of Moll., Index Mollusc. Gronl.) Variety. [Plate vii., fig. 11.] 

 One specimen occurred fossil at Caribou Island which differed in no respect from a recent 

 specimen dredged in 15-30 fathoms at Square Island, which will be further noticed below. 



Bela exarata Moll. (Defrancia exarata Moll., Index Mollusc. Gronl. ; Pleurotoma rugulatus 

 " Moll." Reeve, Icon. Conch, f. 345.) Caribou Island. Common. 



Bela Woodiana Moll. {Pleurotoma harpularia Couth., Bost. Journ. ii., p. 183. Pleurotoma 

 leucostoma Reeve, Icon. Conch, f. 278.) Caribou Island. The most common species of the 

 genus in these deposits, though very rarely found living by us ; it is of large size and much 

 eroded. 



Bela decussata (Couth.) It occurred very rarely at Caribou Island. 



Bela pyramidalis (Strom.) [Pleurotoma rufa Couth.) Not common ; at Hopedale and Cari- 

 bou Island. 



Bela riolacca Mighl. et Adams. (Dcfrancia cylindracea Moll. Ind. Moll. Gronl.; Pleurotoma 

 gronlandica Reeve, 1. c. fig. 343.) Of common occurrence at Caribou Island. 



Buccinum glaciale Linn. Caribou Island, an imperfect specimen. 



Buccinum grbnlandicum Hancock. Annals and Mag. Nat. Hist, xviii., p. 329, pi. v., figs. 8, 9, 

 1846. [Plate vii., fig. 5 Z>.J Pitt's Arm, head of Chateau Bay; one specimen, with the 

 outer coating of shell worn off. 



Buccinum tenue Gray. (Buccinum scalariforme Beck, Stimps., Can. Nat., Oct. 1865, p. 14.) 

 One specimen occurred at Caribou Island, wanting the lip and spire, but showing well 

 the abbreviated longitudinal waves characteristic of the species. 



Buccinum undulaium Moll. (B. undatum Greene, Gould, Dawson ; B. labradorense Reeve, 

 Packard, Can. Nat. viii. p. 416, 1863.) 



Buccinum cretaceum Reeve, Icon. Conch, Packard, Can. Nat. viii., p. 417, pi. ii., fig. 6, 1863. 

 [Plate vii., fig. 7.] This interesting species, now found not uncommonly on the coast of 

 Labrador, also occurs fossil not unfrequently at Caribou Island. It differs in no respect 

 from living forms. 



Fusus (Neptunea) tornatus Gould. Rarely found fossil at Caribou Island, and in the blue 

 clay at the mouth of Salmon River. 



Fusus (Neptunea) labradorensis n. sp. [Plate vii., fig. 8.] Shell fusiform ; whorls moderately 

 convex, sutures deeply impressed, the upper ones somewhat flattened, spire elongated, 

 acute, lower whorl ventricose, covered with rather coarse revolving stria?. On the lower 

 whorl are twenty nearly straight, coarse, flattened folds, which on the succeeding whorls 

 run the entire length of each whorl. Aperture ovate, columella concave, smooth ; canal 

 moderately long, oblique, slightly tortuous, spire a little longer than the shell. Length, 

 one inch; breadth .48 inch. One specimen at Caribou Island. It differs from Fusus pullus 

 Reeve (fig. 89.) in being apparently a much thicker shell, in the longer canal, and in the 

 more ventricose body of the shell, with the coarser revolving lines. 



Fusus tortuosus Reeve, Belcher's last of the Arctic Voyagers, ii., p. 394, pi. 32, fig. 5. Our 

 specimens differ from the description, in the absence of the long tortuous canal which gives 

 the species its name. The fossils have the same convexity of the whorls, which are cov-
