The sets numbered respectively 182 A and 181 were found in clear, 

 running, cold mountain streams, and were probably driven into them by 

 storms or by a sudden rise of the waters ; that marked R at an altitude of 

 10,000 feet. 



*Dr. Lewis considers the large form referred by Binney anil Bland to Succinea avara var. major to be 

 a good species. The name vermeta seems to be discredited in its application to that form. If Messrs. Bin- 

 ney and Bland are correct in refusing to apply the name vermeta to the form in question, it remains foi 

 some future writer to give the species a proper place.
