Diagnosis
ReferenceDiagnosis
E. Billings 1861This species consists of a simple curved tube usually about three inches in length. The larger extremity for about two inches is nearly straight, and the cross section nearly circular. The remainder, to the point, curved so as to make half a whorl of an inch across, or a little less. In this part the tube is not cylindrical but flattened laterally. In most of the specimens the sides are more sharply rounded than the dorsal or ventral aspects. In none that I have seen is the shell preserved, so that the surface characters remain unknown. Some of the fragments shew that the shell near the smaller end is greatly thickened.
