416 LIST OF LABRADOR MARINE ANIMALS. 



T. reticulata Migh. Very abundant, occurring with the preced- 

 ing in 10-50 feet, but most abundant in 15 feet mud. Salmon Bay. 

 , T. acicula Stm. One individual in 50 feet hard bottom. 



Menestho albula Moll. The young were frequent in 2-15 feet sand. 



Lamellaria joerspicua Loven. 15 feet sand and mud. 



JSFatica Jieros Say. Two young dead shells were found at high 

 water mark. 



N'. clausa Sby. Frequent in 15 feet. 



Bela violacea Stm. (Pleurotoma violacea Migh. and Adams.) 

 18 feet. Both this and the bicarinata Couth., which Dr. Stimpson 

 considers but a variation of the violacea, were frequent in 20 feet 

 sand. 



B. decussata Stm. 



B. scalaris, (Defranci a scalaris Moll., Ind. Moll. Gron. Fusus 

 turricula Gould.) 



The European B. turricula, as observed by Morch, is very dif- 

 ferent from the American representative. On a comparison of our 

 shell with several specimens of the • turricula, we find that the 

 shoulder on each whorl ^that gives the shell its turreted appear- 

 ance, is situated more in the middle in B. scalaris. The turricula 

 has twelve longitudinal ridges on each whorl, being fewer and 

 proportionately larger than in our species which has seventeen. 



Our species seems also to be a larger shell. It agrees well with 

 Moller's D. scalaris to which he refers turricula Gould 



B. Woodiana Moll. Fusus harpularius Gould. 



One specimen was dredged with the preceding nave also two 

 specimens of it from Greeuland. It is a shorter and thicker shell 

 than B. scalaris, in which the first whorl is as long as the remain- 

 ing ones together. In this species the first whorl is longer than 

 the rest. The canal is shorter and the aperture rounder. The 

 longitudinal ridges are the same in number, but are less promi- 

 nent, while the revolving lines are much coarser, giving the surface 

 a reticulated appearance. 



B. pyramidalis Stm. 



These species of Bela occurred in sand and mud 15 feet Salmon 

 Bay. B. decussata was the most abundant species. 



Buccinum labradorense Reeve. Icon. Conch., pi. 1, fig. 5. Most 

 abundant just below low water mark. Fine specimens 3^ inches 

 long were frequent ; their egg capsules in large bunches were often 

 deposited at low water mark. This species represents the European 

 B. undatum.
