This is E. flavesctns, Parr., H. striolata, Phil., H. Teresse, 

 Benoit, and H.flavida, Ziegler. The Marchioness Paulucci has 

 recently examined the type of this species and finds it to be a 

 true species equaling and anterior in publication to H. flamda, 

 Ziegler, but the shell which Pfeiffer and other authors have 

 called H. Balmei, and which Shuttleworth has figured under 

 that name in his " Notitiae," is a Hyalina, and can stand as 

 Hyalina Balmei, Shuttlew.
