Or 
MOLLUSCA OF OHIO. 
yEuconulus chersinus (Say, Helix). 
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. 
tEuconulus sterkii (Dall., Hyalina). x 
Summit Co.! (Pettingell) ; Tuscarawas Co., where the types 
were collected (St.). Probably over the state, but 
overlooked for its small size, like some other minute 
mollusca. 
LIMACIDA. 
*LIMAX MAXIMUS Linné. 
Cincinnati (Lindahl); Wooster, Agricultural Station! (Web- 
ster); Nursery east of Painesville (St.). Introduced 
from Europe. 
LIMAX FLAVUS Linné, introduced from Europe; probably 
in greenhouses and nurseries; I have seen no specimens. 
AGRIOLIMAX AGRESTIS (Linné, 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 ty eel brownish form, in striking con- 
trast. [Mr. Geo. H. Clapp has found the same at 
Pittsburg, Pa.] 
CIRCINARIIDA:. 
Circinaria concava (Say, Helix), Selenites, Macrocylis concava. 
Over the state, common. Appears to be absent from Put- 
in Bay, t. Allen. 
HELICIDA—POLYGYRINA. 
Polygyra profunda (Say, Helix), Mesodon projunda. 
Over the state. Albino specimens (without reddish bands) 
are occasionally found. 
Polygyra sayana Pilsbry, Helix diodonta Say, 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.
