Shell small, elongated, thin, white, glossy; spire ver)' acute, curved into scythe-shajje; 

 whorls ten, flat; suture indistinct, not impressed; body-whorl subangular at base; base elongated; 

 aperture pyriform, seemingly api)re.ssed to side of shell out of its normal position; outer lip acute and

Distinguishable froin E. miani^ by subangulated body-whorl, cc'cciitric .ipcrtiirc 

 and curved spire; distinguishable from E. hnstnta by curved spin' and more eccentric 

 aperture. The specimens described were identified by Dr. Dail.

 the upper San Pedro series at San Pedro. The specimen figured is from the lower 

 San Pedro series at Deadman Island, and is now in (he collectimi of Delos Arnold.
