Remarks. — This specimen, which I owe to the kindness of Dr. Hartman, of "West- 

 chester, Penna., was no doubt sent to him by Dr. Showalter. It is distinct from any 

 species I have before seen, and is more nearly allied in outline to Babylonicum (nobis) 

 than any other species I know. It differs in not being umbilicate, in not having a 

 square shoulder, and in being yellowish horn-color. It is impressed below the hem- 

 like margin of the suture, which the other is not. It is also near to recta, Anth., 

 but is stouter, is of a light color, and has a more twisted columella. The specimen 

 in my possession is nearly an inch in length. With a perfect spire it would exceed 

 an inch. All is imperfect about the second whorl, but there are indications of there 

 being at least six. One specimen has no bands, the other has three obscure ones. 

 The aperture is about half the length of the shell. The hem is rather narrow and 

 is well defined. I have great pleasure in naming this species after my friend Dr. 

 Hartman, who has done so much to promote natural science.
