Alvania carinata is a species of small sea snail, a marine gastropod mollusk or micromollusk in the family Rissoidae.[1]
The length of the shell attains 3.4 mm, its diameter 2.6 mm.
(Described as Rissoa striatula) The rather solid shell is opaque and yellowish white. It is thinly longitudinally striate in the interstices between much stronger spiral ridges, which carinate and shoulder the whorls. The aperture is a little dilated below, smooth within, ridged-varicose externally.[2]
