P. CONTRACTA, Say. Abundant along with arniifera. 



P. CORTICARIA, Say. Common with contracta and armifera. It 

 prefers beds of old leaves not much decayed but damp. 



It may be found between the leaves. Some of my 

 correspondents pronounce my corticaria to be Carychium 

 exiguuui. It is certain it never reaches any damper places 

 than the Pupas, with which it is associated. 



SucciNEA ovALis, Gould. Abundant in marshes, by margins of 

 ponds; associated with Li/nuceas; shell fragile. 



S. AVARA, Say. Somewhat rare; closely associated with C. sub- 

 cylindrica and found most abundantly in same region. 



It prefers rather loamy, loose earth, which it seems to 

 penetrate the same as C. suhcyliudrica. It is abundant as 

 a fossil in Loess in this city. 



S. OELiQUA, Say. Abundant on Geneva Island with H. miiltilineaia. 

 They are closely alike in habit. * 



Shell much stronger than oval is; they do not seem to 

 be hermaphrodite. 



Philomycidas. 



Tebennophorus carolinensis, Bosc. Rare; about old stumps 

 or decayed logs; a fine moUusk. 



Limnseidae. 



Limn^a reflexa. Say. One variety abundant in swamps with 

 flags or reeds. Tlie typical reflexa is scarce. 



L. reflexa var. zebra. Abundant in this vicinity. This var. is 

 generally marked by white or light bands along the lines 

 of growth alternating with dark or brown of usual color of
