60 THE NAUTILUS. 



was brought to our Bay in large 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. 



LYMN.EA AURICULARIA LINNE IN CANADA. On July 23, 1911, 

 I found Lymnsea 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 POLYGYRA (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 obstricta. There they were typical, large, fine 

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

 WETHERBY, in letter, about 1898. 



LIMAX MAXIMUS ON NANTUCKET ISLAND. When recently at 

 the town of Nantucket, Mass., I found Limax maximus 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 dark edged. I 

 also found Agriolimax agrestis at Nantucket; likewise on Cutty- 

 hunk, where it was the only terrestrial species I 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.
