60 THE NAUTILUS. 



was brought to our Bay in larj{e quantities, or it may have been 

 planted there Fred L. Button, Oakland, Cal., July 20, 1911. 



Epiphragmophora fidelis I note in the Nautilus for June, 



1911, that Mr. Harry Edson regards my record of Epiphragmophora 

 jidelis from San Mateo Point, California, as erroneous. I would 

 state that the specimens were E. Jidelis without the slightest doubt 

 Furthermore, I again collected living specimens in the same locality 

 on August 14, 1910 E. W. Gifford. 



Ltmn^a auricularia Linne in Canada. — On July 23, 1911, 

 I found Lymnaea auricularia Linne inhabiting a chain of pools on 

 the beach of Lake Erie at Kingsville, Ontario, about opposite San- 

 dusky. Young individuals were fairly numerous, but the only ma- 

 ture shell seen was a dead one John A. Allen. 



Locality for Poltgtra (Triodopsis) obstricta Say. — 

 Beyond Murphreesboro (Tennessee) there is a road turning square 

 to the right from the main pike. About half or three-quarters of a 

 mile out, on the right-hand side of the road, is the only good locality 

 I ever found for ohstricta. There they were typical, large, fine 

 shells. They were found about dead logs and old slumps. — A. G. 

 Wetherby, in letter, about 1898. 



LiMAX MAXiMus ON Nantucket Island. — When recently at 

 the town of Nantucket, Mass., I found Limax inaximus well estab- 

 lished. There were two varietal forms: (1) Mantle spotted, the 

 spots partly confluent; body marbled and with four gray-brown 

 bands, the two inner with blackish spots. (2) Mantle marbled ; 

 body gray with three light bands, the inner rather da'k edged. I 

 also found Agriolimax agrestis at Nantucket; likewise on Cutty- 

 hunk, where it was the only terrestrial species 1 could find. 



I take this opportunity to note that Helix hortensis var. bicolor 

 Ckll,, 1891 (shell pink with upper part of spire yellow), is preoccu- 

 pied by var. bicolor Picard, 1840. My variety may be named 

 dichroa. — T. D, A. Cockerell.

 campaign for Unionidse in Wept Virginia.
