A doubtful form, 



I Lave tbougbt it best not to suppress a single form tbat Messrs. Gabb 

 and Horn have catalogued. I have in my cabinet at least sixteen— pro- 

 bably nineteen— of the so-called species from Timber Creek, New Jersey, 

 and I find that that number at least may be allowed to stand ; but even 

 the specific names of some of these may very safely be reduced to 

 synonyms. In comparing them with European species I cannot detect 

 any material difference between the American forms and those described 

 by Goldfuss and Hagenow.
