Description

The length of the holotype attains (the early whorls lost) 26.5 mm, its diameter 8.3 mm; ​6 1⁄2 whorls remaining.

(Original description) This species is very similar to Carinodrillia elocata, but it is more slender with a longer anterior canal and a deeper posterior sinus. The anal fasciole and the spaces between the spiral ridges are distinctly striate spirally, with in each interval about 6 striae. There are seven broad, rounded axial folds on the penultimate whorl and on the body whorl, weakening on the anal fasciole. On the face of the body whorl there are 18 narrow, high spiral ridges, a smaller cord above the upper one and a strong, acute cord below the suture. The outer lip is smooth within. The inner lip is a little raised. The anal sinus is deep, rounded posteriorly and contracted a little anteriorly.[2]

Distribution

Fossils of this marine species were found in Tertiary strata of the Dominican Republic.

gollark: As an alternative to either using a run-from-memory-y live USB or repartitioning *very carefully*, you could just use a VM with access to the USB stick.
gollark: My Arch (btw) live USB just has a regular Arch install, but on a live USB.
gollark: The live ISOs use a compressed non-writable filesystem image of some sort mostly.
gollark: There's windows software like that.
gollark: Well, on Linux you can use 'tmpfs" technology.
