THE NAUTILUS. 11 



NEW SPECIES OF SHELLS COLLECTED BY MR. JOHN MACOUN AT 



BERKLEY SOUND, VANCOUVER ISLAND, B. C. By William H. 

 Dall and Paul Bartscb. (Canada, Dept. of Mines, Memoir no. 

 14-N. 1910.) In reporting upon this collection the first to be 

 made on the ocean side of Vancouver Island attention is called to 

 the interesting fact that the inland passages of this region, "perhaps 

 affected by the discharge of cold water from glacier-fed streams, and 

 the shutting-off of the sun's rays from the narrow passages by their 

 mountainous shores and prevalent fogs, is markedly of a more boreal 

 character " than the ocean coast. New species are described in the 

 genera, Leda, Beta, Mangilia, Soreotrophon, Epitonium, Turbonilla, 

 Odostomia and JBittium, all figured. 



NOTES. 



SPONDYLUS ECHINATUS MARTYN I have recently received from 

 Mr. J. H. Holmes some fine examples of Spondylus echinatus, which 

 also rival in size and beauty the S. pictorum of the Gulf of Cali- 

 fornia. One of the specimens measures five inches in length, and 

 Mr. Holmes writes that " some are six inches long." They were ob- 

 tained in ten fathoms near Rock Island, one of the Anclote Keys, 

 Florida C. W. JOHNSON. 



LYMN^EA AURICULARIA IN OHIO. On March 21st last I found 

 Radix auricularia L. in numbers in a marshy stream forming the 

 northeast border of Toledo, Ohio, less than 100 feet from Maumee 

 Bay, Lake Erie. The shells were in two to eight inches of water, 

 moving slowly about on the bottom, upon sticks, and some, afloat at 

 the surface, were in the position of coition. Dead shells of auricu- 

 laria were found also on the marshy borders of a bayou farther to 

 the north. Near this bayou are several greenhouses and I am in- 

 formed that it is the custom of the florists to import potted azaleas 

 from Holland and Belgium. In this way eggs may have been 

 brought here and reached the open water through drains. The pres- 

 ence of a large colony and the indications that another exists close 

 by would appear to bear out the comment of Mr. Frank Collins 

 Baker, in his recent work upon the Lymnseidce, that " there is no 

 reason why it (auricularia) would not thrive in the ponds and rivers 

 of certain favorable localities of this country."
