rare. The type of the genus is a reversed specimen of Campeloma ponderosuin from 

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



PlanorheUa campanulata Say. Very abundant in all parts of Tippecanoe Lake. 



Helisoma trirolvis Say. Two specimens from Turkey Lake ; three specimens 

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

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

 localities. 



Limnophym httmilis Say. Five specimens of this small limnsid were obtained 

 along the shores of Turkey Lake. 



Liiiuiophysa caperata Miiller. A single specimen of this common form only 

 "was secured. It came from Turkey Lake. 



Phym ancil'aria 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. 



Phym c/yrina S&y. Only two specimens of the "tadpole" physa appear in 

 the collections, and these came from Ti^jpecanoe Lake. It is one of the most 

 widely distributed and most abundant of the Limnst^idje. 



Goniobasis pulchella 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 Goniobmis livescens Menke, a form decidedly characteristic of the lake drainage. 



Pleitrocera siibulare Lea. Very abundant in Lake Tippecanoe, from which 

 many dead examples were seen. 



Valvata iricarinaia Sav. A single specimen from Tippecanoe Lake. 



LAND MOLLUSCA. 



Limax campestris Binney. Four specimens of this widely distributed form 

 ■were obtained from Vawter Park. 



Succinea obliqua Sav. This species is represented by ten alcoholic specimens. 

 All taken at Vawter Park. 



Zonites arborens 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 moHuscan 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 moUusks.
