Diagnosis
| Reference | Diagnosis | |
|---|---|---|
| J. B. Knight 1931 | Extremely small, with few whorls; sub-oval, the shape suggesting a small moth with an injured wing; spire very short, mammillary; sutures indistinct; inductura very slightly thickened; siphonal notch rather conspicuous; siphonal fold well defined and at a low angle to axis of shell; outer lip flaring; surface smooth, unornamented; color in life unknown, though the last shell matter added to the outer lip of the holotype is of a lighter gray than the rest of the shell and its inductura preserves traces of black pigment.
This tiny species is as far as I know unique. I have considered the possibility that the specimens included might be the young of some larger species but find nothing to sustain such a supposition. They are definite-ly not referable to Soleniscus. The coiling of the earlier whorls alone would exclude them. |
