I believe that I have again detected the long misunderstood species of Say in some 
specimens which agree very well with his words “ polita ” and nevertheless “anfr. 
corrugati,” “rufescens, subtus pallidior.” The very shining surface, with unequal 
plait-like strie, and the distinctly paler yellowish, or even greenish, colour of the 
lower side are characteristic of the species before me. Spiral strize are present, but 
very fine, scarcely perceptible under an ordinary lens, and very numerous. The same 
characters are to be found in the specimens of 0. angiomphala given by Strebel 
himself to the Berlin Museum ; also the fine spiral strie, which he does not note in 
his otherwise very good description. The varieties ¢ and d differ by the greenish 
colour; ¢ (deppeana) shows all the mentioned peculiarities of sculpture, and forms
