THE GEOLOGY OK THE LABRADOR COAST. 



Buccinuvi undatum Linn. {B. undatum Greene, 

 Gould, Dawson ; B. labradorense Reeve, Packard, Can. 

 Nat. viii. p. 416, 1863.) 



Tritonofusus cretaceus (JBuccinum cretaceum Reeve, 

 Icon. Conch ; Packard, Can. Nat. viii., p. 

 417, pi. ii. fig. 6, 1863.) 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 (^Neptuned) tornatus Gould, 

 Rarely found fossil at Caribou Island, and 

 in the blue clay at the mouth of Salmon 

 River. 



Fusus (Neptunea) labradorensis Pack. 



TRITONOFUSUS r>i ii r t i i 



CRETACEUS. Shcll fusiform ; whorls moderately convex, 

 sutures deeply impressed, the upper ones somewhat flat- 

 tened, spire elongated, acute, lower whorl ventricose, 

 covered with rather coarse revolving striae. 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 con- 

 cave, 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.
