Holotype 29.5 mm length, light in weight, conically elongated (width/ length ratio 0.36) . Protoconch missing. Teleoconch of 8 whorls; whorls shouldered, carinated; carina on early whorls almost central, progressing anteriorly on later whorls. Suture deep . Axial sculpture of numerous arched thread on shoulder, evanescing at carina, weakly appearing again anterior to carina; last whorl with numerous, relatively wide, low, flat axial threads ; threads becoming weaker and narrower when crossing spiral cords. Spiral sculpture of two to four strong threads posterior to carina, creating reticulations at shoulder when crossing over axial elements; threads followed by a heavy, nodulose, otherwise smooth cord and one or two undulating threads anterior to carina; last whorl with strong, flat, evenly distributed spiral cords; cords as wide as interspaces, minutely wrinkled by axial threads. Color light cream.
Discussion:- Pers. Comment Ed Petuch: A late Pleistocene fossil; a composite species because Paratype 7 is a specimen of Conus armiger Crosse, 1858.
