| Size under dissecting microscope: 290µm Size under compound microscope: 280µm |
| Morphology: This is one of the few easily identified peltospirids. It is a large protoconch with strong lineation extending about 2/3 of the way to the aperture. Like most peltospirids, the aperture is straight viewed from the side and flares out to the sides when viewed from from the top, as in the third photo above. There is also an abrupt ridge on either side of the base near the axis of coiling. The shell is transparent and robust; they are seldom found damaged. |

Rhynchopelta is unlikely to be confused with any other protoconch. The only other peltospirid protoconch close to it in size, Ctenopelta porifera (pictured at left), is quite different morphologically. |
