en dessous. L’ombilic parait en proportion plus large. L’ Helix Haydent Gabb, 
en différe par ses cétes spirales mieux marquées, tres apparentes des deux cotes, 
sa caréne plus aigué, et son ombilic moindre. L’H. bruneri présente avec 
LH. Hemphill, 4 peu prés les mémes différences qu’avec L’H. Coopert. Sauf les 
cétes spirales, cette coquille présente les plus grands rapports de forme avec 
DH. (Xerophila) filimargo, de la Crimée. L’ombilic et la caréne sont aussi 
presque identiques. (Ancey.)

I have given the original description above, and figures of one of the original

It may prove a carinated variety of perspectiva, but apparently deserves to 
be designated by a specific name.
