THE NAUTILUS. 89 



Pi's, trapezoideum St. (described in the NAUTILUS, IX, p. 124, 

 1896), from the middle Atlantic States, and probably the same from 

 Grand Rapids, Michigan, is very different from neglectum, yet there 

 may be intermediate forms connecting the two. Should that prove 

 true, trapezoideum would probably better be regarded as a specially 

 differentiated form, a variety of neglectum, and not vice versa. 

 Priority cannot be considered if there are better reasons for a differ- 

 ent point of view. 



THE BROOKLYN CONCHOLOGICAL CLUB. 



To the Nautilus : 



The Brooklyn Conchological Club was formed over two years ago 

 by a number of collectors and admirers of shells. Several of the 

 members have extensive and valuable collections, the product of 

 many years of careful selection and world-wide correspondence with 

 collectors. THE NAUTILUS is a welcome visitor at the club. Two 

 of our members' names are found on its advertising pages, and 

 occasionally an article appears from the pen of our esteemed friend 

 and conchologist, Mr. Sloman Rons. We hope to hear of similar 

 clubs in other cities, and from individual collectors. 



At the October meeting of the Brooklyn Conchological Club, Mr. 

 Maxwell Smith exhibited specimens of the shells collected by him 

 last summer in Otsego County, N. Y., also a map of the stations 

 visited. Mr. Smith gave an interesting account of his experience in 

 collecting. A list of the shells exhibited includes 54 species.

BY MAXWELL SMITH. 



The following species were all found in Otsego Co., with the ex- 

 ception of those from Weaver and Young's Lakes (Little Lakes), 

 Herkimer Co. The collection was made in July and August, 1906. 

 It is interesting to note that Lymnsea yracilts Jay was reported from 

 Canadarago Lake previous to 1870 by a number of authors. I 

 hunted diligently for this species but did not find it. From Allan
