GENERAL NOTES. 



Some American Cannibals. — Ed. Nautilus, Dear Sir. — Dur- 

 ing a recent stroll in Fairraount Park I found beneath an old rail- 

 road tie about thirty healthy looking Limax agrestis, Linn. These 

 I placed in a small collecting box which already contained quite 

 half as many L. campestris, Binney. 



On opening the box a half hour later I found, to my surprise, that 

 two of the campestris were rapidly disappearing w'ithin the jaws of 

 a pair of agrestis. 



Having no means to separate the species I closed the box again 

 and left it so for about twelve hours. 



Upon reopening it there was but one campestris living. With 

 exception of a few reddish stains not a vestige of the others could be 

 discovered. 



Of course the living one could tell no tales, but the fact remained 

 that all the rest of its kindred hadinvoluntarily evolved into Limax 

 agrestis, Linn. 



Moral, when Bulls are near let Conservatives beware. — John Ford, 

 Phila., Oct. 1890. 



Exchange. — I have for exchange twenty-five species of Unios 

 from Illinois and Spoon river, including about two hundred very 

 fine Anodonta suborbicnlata Say. 



Wanted other Unios and Sea shell. — Dr. W. S. Strode, Bernadotte, 

 111.
