tare. The type of the genus is a reversed specimen of Campelvma ponderomm from 

 the Ohio River, taken by Kafinesque near Louisville, Ky. 



Planorbdla eampcmulata Say. Very abundant in all parts of Tippecanoe Lake. 



Ilelisomn trimlrix Say. Two specimens from Turkey Lake; three specimens 

 from Turkey Creek. The form submitted from Turkey Creek is a very large one, 

 and is rather heavy in texture. The species must be very abundant in favorable 

 localities. 



Liinnnphi/xu. hiimilis Say. Five specimens of this small limnseid were obtained 

 along the shores of Turkey Lake. 



Limnophysa eaperata Miiller. A single specimen of this common form only 

 was secured. It came from Turkey Lake. 



Physa aneil'arw Say. Four specimens taken alive, entirely white, from 

 Turkey Lake. This shell is usually honey yellow in coloration, but these speci- 

 mens were a snow white. 



Physa gyrina Say. Only two specimens of the "tadpole" physa appear in 

 the collections, and these came from Tippecanoe Lake. It is one of the most 

 widely distributed and most abundant of the Limnaeida;. 



Goniobusix pulehella Anthony. Nine specimens from Turkey Lake ; very 

 abundant in Tippecanoe Lake, from which many dead specimens were submitted. 

 This form is widely distributed throughout Indiana. Sometimes associated with it 

 is Gonwbaxix lirexcens Menke, a form decidedly characteristic of the lake drainage. 



Pleurocera mbulare Lea. Very abundant in Lake Tippecanoe, from which 

 many dead examples were seen. 



Valvulu Iricarinata Say. A single specimen from Tippecanoe Lake. 



LAND MOLLUSCA. 



Lima.r campestris Binney. Four specimens of this widely distributed form 

 were obtained from Vawter Park. 



Succinea obliqu.a Say. This species is represented by ten alcoholic specimens. 

 All taken at Vawter Park. 



Zonites arboreus Say. Three alcoholic specimens from Vawter Park. 



None of the univalves present features worthy of special mention. The 

 whole collection is rather the result of incidental work than of careful collecting, 

 and is to be taken as somewhat indicative of the wealth of molluscan life in 

 favored localities in Indiana. It is submitted as a local contribution, in the form 

 of a special report, that may help to a general knowledge of Indiana mollusks.
