THE NAUTILUS. 17 



from British Columbia (though some have been found in neighbour- 

 ing seas), and four species are new to science. My best thanks are 

 due to Dr. Ball for kindly determining new and doubtful material, 

 and species so identified are marked in the accompanying list by an 

 asterisk. 



It will be noticed that the range of several Californian species 

 receives a considerable extension, as in the case of Diala marmorea 

 Cpr., Euliina falcata Cpr., Ischnochiton radians Cpr., Lepidopleums 

 rugatus Cpr., Chrysallida cincta Cpr., Phasiane/la pulloides Cpr., 

 Tornatina harpa Ball, and Turbonilla stylina Cpr., etc. 



Of northern species the southward range is extended of Buccinum 

 plectrum Stimps. (now first established as living in our waters) of 

 Trichotropis borealia Br. & Sby., and of Sipho verkriizeni Kobelt. 

 The two last mentioned species occur at Alert Bay in company with 

 an unusual abundance of boreal and circumpolar species such as 

 Buccinum cyaneum Brug., Bela violacea M. & A., Margarita helicina 

 0. Fab., CryptobranchiaconcKntrica^lidd., Lepidopleums cancellatus 

 Sby., Orenella deeussata Mont., etc. 



Of the four new species, three belong to genera new to our waters ; 

 viz. Rissoina, Molleria and Pliasaniella. The fourth species belongs 

 to a subgenus (Mumiola) of Odostomia especially Japanese in its 

 recorded species. 



Most of the following additions are of small shells, of which, how- 

 ever, we are still far from having on record a normal proportion. 



The stations quoted in the following lists are arranged in their 

 order passing from the south towards the north. 



Station 1. Near Victoria, Vancouver Island, in 60 fathoms, fine 

 clean sand. Collected by the Natural History Society of B. C. 

 March 14, 1896. 



Station 2. Near Alert Bay, Queen Charlotte Sound, northeast of 

 Vancouver Island, 20 fathoms, small gravel. Collector, C. F. N. 

 July, 1895. 



Station 3. North side of the entrance to Curnshewa Inlet, Queen 

 Charlotte Islands, 10-20 fathoms, small broken shells and sand. 

 Collector, C. F. N. Sept., 1895. 



Station 4. East end of Skidegate Inlet, Queen Charlotte Islands, 

 sand and mud. Collector, C. F. N. August, 1895. 



Station 5. Bawson Harbour, west end of Skidegate Inlet, Queen 

 Charlotte Islands, 20 fathoms., broken shells. Collector, C. F. N.
