SUCCINEIDAE 



127 



Illinois and is at present known from only four places; however, 

 these represent almost the length of the state. Specimens have 

 been seen from Will, Peoria, Tazewell and Washington counties. 



SUCCINEA SALLEANA Pfeiffer 



The shell of Succinea salleana may be distinguished from 

 that of Succinea retusa, which it greatly resembles, by the 

 former's shorter spire and its longer, wider aperture, which 

 flares more in the lower part than does that 

 of retusa. The columellar region is some- 

 what indented, and the small callus bends 

 around into the upper part of the aperture 

 in a dififerent manner than does that of 

 retusa. Succinea salleana occurs near water, 

 and its handsome, gold-tinted, amber shell 

 attracts immediate attention. Average shells 

 are about five-eighths of an inch (16 mm.) 

 in height. 



The only specimens at present known 

 from Illinois were collected by Leslie Hu- 

 bricht from Pittsburg Lake, near East St. 

 Louis, St. Clair County, and from Hill Lake, three miles north- 

 west of Columbia, a town that is located in Monroe County. 



Succinea salleana is a species common in Louisiana, and its 

 presence in Illinois, more than 400 miles north, is one of the 

 perplexing features of distribution. Its abundance at both of 

 the recorded Illinois localities indicates that it has been in the 

 state for a long time and that it has either been overlooked 

 by previous students or else erroneously identified as one of the 

 retusa group. 



January, 1758: Does Mary cough in the night? Two or 

 three snails boiled in her barley-water or tea-water, or what- 

 ever she drinks might be of great service to her; taken in time 

 they have done wonderful cures. She must know nothing of it. 

 They give no manner of taste. It would be best if nobody 

 should know but yourself, and I should imagine six or eight 

 boiled in a quart of water and strained off and put into a bottle, 

 would be a good way, adding a spoonful or two of that to every 

 liquid she takes. They must be fresh done every two or three 

 days, otherwise they grow too thick. — Mary (Granville)
