MOLLUSCA OF OHIO. 375 



fEuconulus chersinus (Say, Helixj. 



Over the state, common; in some sections more common 

 than fulvus, e. g. in Tuscarawas Co. In earlier descrip- 

 tive works, and lists, these two species were understood 

 as one, under one name or the other. 

 jEuconulus sterkii (Dall., Hyalina). X 



Summit Co.! (Pettingell) ; Tuscarawas Co., where the types 

 were collected (St. J. Probably over the state, but 

 overlooked for its small size, like some other minute 

 mollusca. 



LIMACIDvE. 



fLIMAX MAXIMUS Linne. 



Cincinnati (Lindahl) ; Wooster, Agricultural Station! (Web- 

 ster); Nursery east of Painesville (St.). Introduced 

 from Europe. 

 LIMAX FLAVUS Linne, introduced from Europe; probably 

 • • in greenhouses and nurseries; I have seen no specimens. 



AGRIOLIMAX AGRESTIS (Linne, Limax). 



Cincinnati; I have found it at Cleveland, Garrettsville, 

 Ravenna, Navarre, Tiffin, Defiance. Introduced from 

 Europe.* 

 Agriolimax campestris (Binney, Limax). 



Over the state, common everywhere. A bluish gray form, or 

 eventually a variety (plumbeus) was found at Scio, 

 Harrison Co. (St.), adult and young specimens, side by 

 side with the typical, brownish form, in striking con- 

 trast. [Mr. Geo. H. Clapp has found the same at 

 Pittsburg, Pa.] 



CIRCINARIID^. 



Circinaria concava (Say, Helix), Selenites, Macrocylis concava. 

 Over the state, common. Appears to be absent from Put- 

 in Bay, t. Allen. 



HELICID^ POLYGYRIXJE. 



Polygyra profunda (Say, Helix), Mesodon profunda. 



Over the state. Albino specimens (without reddish bands) 

 are occasionally found. 

 Polygyra sayana Pilsbry, Helix diodontaSay, sayi Binney. 



Cincinnati (Shaffer). 

 Polygyra multilineata (Say, Helix). 



Over the state, especially in river bottoms, swamps, etc. 

 Decidedly variable, with respect to size, shape and 

 color. Specimens without red bands (form alba), and 

 reddish all over (form rubra) are occasionally found. 



*Some conchologists, however, believe it to be native of North 

 America, being so widely distributed.
