It is universally allowed that the Pupa cylindracea of 

 Da Costa is the Pupa uj7ibilicata of Drap. ; this name, therefore, 

 takes precedence of Draparnaud's to which we have become so 

 well accustomed. 



Pupa muscorum L. — The type specimen of this shell 

 still exists in the Linnean Cabinet, and is the edentate form, 

 which thus becomes the type. The var. unidentata of C. Pfr. 

 will now indicate the specimens with the single denticle on the 

 body whorl, previously considered to be the typical form. 



In the genus Vertigo we have reduced the V. lilljeborgi 

 to a variety only of vioulinsiajta and have also placed V. tumida 

 as a var. of V. pusilla, in which course we have the support of 

 the author, Dr. Westerlund. 



C. rugosa v. schlechtii Zelebor. — Dr. Jeffreys referred 

 some peculiar shells of the var. di/bia, found by Mr. W. D. 

 Sutton in Northumberland and Durham, to the above variety. 

 Dr. Westerlund denies that they represent the form named 

 thus by Zelebor, and has therefore re-named the form su/tont, 

 a course in which Dr. Bottger and others concur. They, 

 however, include in the var. suttoni the large coarsely 

 striated form of var. dtibia, especially characteristic of the North 

 of England, but we are unable to fall in with this view, and for 

 the present retain this form under its old name of duhia. 



Cochlicopa lubrica v. morseana Doherty is a very 

 large and long form of the species described by Doherty from 

 American specimens some years ago. Its claim to British rank 

 rests upon its discovery in Hampshire by the Rev. W. W. Eyre, 

 of Swarraton, near Alresford. 



The Succineae have at all times been a fertile source of 

 perplexity, and to avoid further confusion we retain the three 

 well-known species only — pjitris, elegans, and oblonga — which 

 we consider to be the only British species entitled to specific 

 rank. S. stagnalis and S. vitrea we regard as forms of putris,
