''Admetula italica'' is a species of sea snail, a marine gastropod mollusk in the family Cancellariidae, the nutmeg snails. 〔(Verhecken A. (2007). ''Revision of the Cancellariidae (Mollusca, Neogastropoda, Cancellarioidea) of the eastern Atlantic (40°N-40°S) and the Mediterranean''. Zoosystema : 29(2): 281-364 p. 286-289 )〕 ==Description== The white, turriculate shell grows to a length of 11.5 mm. The paucispiral protoconch has 1¾ whorls. The teleoconch consists of 3¼ rounded whorls with spiral ridges, axially crossed by 16 to 17 distinct ribs. The ribs become confused at the bottom of the body whorl. On the top of each whorl these ribs disappear into the flat sutural zone between the whorls. The aperture is ovoid with the outer lip lacking striae. The columella is strongly inclined abaxially showing two folds, with the rim of the siphonal canal forming the third fold. There is no umbilicus.〔
