Description

The length of the shell varies between 14 mm and 22 mm.

(Original description) The rather thick shell is oblong, pyramidal and pale brownish black. The whorls are smooth, encircled with a single row of granules near the suture, longitudinally ribbed below. The aperture is short. The siphonal canal is very short. The sinus is rounded.[2]

Distribution

This species occurs in the Pacific Ocean off Panama.

gollark: SIMD is even more weird and specific on x86. Especially AVX-512, because Intel seems to randomly implement different subsets of that on their different products.
gollark: They seem quite cool, but cost about six times as much as my computer did, so meh.
gollark: The open-source-ish PowerPC thing?
gollark: When stuff like this exists for a while it basically always gets random junk tacked on because someone thinks they need it.
gollark: IIRC an advantage of ARM used to be not having instruction-to-microinstruction conversion like x86 does, but I think their cores do that now.
