| dm | conch shape | whorl cross section shape | whorl expansion |
|---|---|---|---|
| 2 mm | thickly pachyconic; subevolute (ww/dm ~0.80; uw/dm ~0.42) | strongly depressed; strongly embracing (ww/wh ~2.50; IZR ~0.35) | moderate (WER ~1.80) |
| 5 mm | thinly globular; subinvolute (ww/dm ~0.90; uw/dm ~0.25) | strongly depressed; very strongly embracing (ww/wh ~2.00; IZR ~0.45) | moderate (WER ~1.80) |
| 15 mm | thickly pachyconic; involute (ww/dm ~0.75; uw/dm ~0.05) | weakly depressed; very strongly embracing (ww/wh ~1.30; IZR ~0.55) | moderate (WER ~1.95) |
| 30 mm | thickly discoidal; involute (ww/dm = 0.50–0.60; uw/dm ~0.00) | weakly compressed to weakly depressed; very strongly embracing (ww/wh = 0.90–1.10; IZR ~0.50) | moderate (WER = 1.80– 1.95) |
| 50 mm | thickly discoidal; involute (ww/dm = 0.45–0.55; uw/dm ~0.00) | weakly compressed; very strongly embracing (ww/wh = 0.80–0.90; IZR ~0.50) | Moderate to high (WER = 1.90– 2.05) |
