Diagnosis
ReferenceDiagnosis
E. Billings 1861This species consists of a simple conical tube, so coiled as to make two whorls within a circle of one inch and a half in diameter. At the aperture the cross section of the tube is nearly circular, and five lines in diameter in a specimen which measures one inch and a half across the whole coil. The inner or apical whorl is usually about half an inch across. The remainder being not so sharply curved, completes only a second whorl at a diameter of one inch and a half. Most of the specimens that I have seen consist of only one whorl and a half, but we have some imperfect ones of two whorls. In the casts of the interior an obtuse carination is sometimes seen on one side. The surface of the shell appears to be smooth, but owing to the peculiar state of preservation of these fossils, this point cannot yet be determined with certainty.
