Description

The length of the shell attains 6.2 mm, its diameter 2.5 mm.

(Original description) The small, fusiform, short, stout shell is whitish, with three obscure pale brownish spiral bands on the body whorl. The protoconch is minute, translucent, and contains about one whorl with somewhat over four subsequent whorls in the teleoconch The suture is appressed and obscure. The spiral sculpture consists of numerous very fine equal close-set threads over the whole surface. The axial sculpture consists of seven strong rounded somewhat sigmoid ribs, slightly shouldered near the suture, continuous up the spire and obliquely retract ive posteriorly. There are no obvious incremental lines. The ribs extend from the siphonal canal to the suture on the body whorl. The aperture is narrow,. The anal sulcus is shallow and rounded. The outer lip is broadly infolded, smooth within. The inner lip is smooth, not callous. The siphonal canal is hardly differentiated.[2]

Distribution

This marine species occurs in the Pacific Ocean off Panama.

gollark: There are proof of stake cryptocurrencies without the mining resource waste, actually.
gollark: In that transfers still take ages some of the time and it seems overreliant on just trusting other banks instead of technological solutions.
