Danielsi was at first thought to be a typical Lymn&a, but an 

 examination of the genitalia shows it to be a Galba closely allied to 

 palustris and re flex a. The species is named in honor of Mr. L. E. 

 Daniels of LaPorte, Indiana, who first made known this distinct and 

 handsome species. It is an interesting circumstance that so large and 

 distinct a Lymnaeid should have been unnoticed in a region so thor- 

 oughly explored as the state of Indiana.

SHELL: Acutely conic, varying from thin to rather thick; 

 periostracum light yellowish horn to black ; surface dull to shining ; 

 sculpture consisting of rather heavy growth lines crossed by impressed 

 spiral lines; very rarely malleated; whorls 6-7, moderately convex, 

 rapidly increasing in diameter, the body whorl usually somewhat 

 obese; nuclear whorls dark chestnut, rounded, the first whorl some- 

 what larger than in palustris and reflexa; spire long and acutely conic ; 

 sutures well impressed, deeply so in many specimens, and sometimes 

 bordered below by a dark band; aperture nearly elliptical, sometimes
