Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| P. E. Raymond 1906 | Shell small, loosely coiled ; apex acute, incurved, but not making a closed volution. The shell is roughly rectangular in cross section, flattened on top, sloping outward and downward on the side and obtusely angulated at the lower angle ; rounded below and on the inside. The specimen is a cast and does not show any surface markings. This species may be separated from both Eccyliopterus fredericus and Eccyliopterus proclivis by its subrectangular cross-section. |
