Oxychilus alliarius, common name the "garlic snail" or "garlic glass-snail", is a species of small air-breathing land snail, a terrestrial pulmonate gastropod mollusk in the family Oxychilidae, the glass snails.
Both the specific name and the common name refer to the fact that when this animal is disturbed, it gives off a strong smell similar to that of raw garlic or onions.
Description
For explanation of terms used see article gastropod shell.

The whorls from whorl 3 onwards are more narrowly coiled than in O. cellarius, the last whorl descending lower. The umbilicus is wide (1/6 of diameter). The shell is smooth, shiny, weakly reddish to greenish brown. The animal is blackish blue. Anatomy: The internal ornamentation of the proximal penis consisting of not more than four longitudinal pleats, usually straight, sometimes slightly wavy, but never laterally branched or papillate.[3]
