Description The length of the shell varies between 31 mm and 62 mm.
The white, slender shell has a fusiform shape It contains 9 -10 whorls. The whorls are angulated in the middle, concave in the upper portion and convex below. The whorls are bordered below the suture with a thickened margin. The longitudinal ribs are nodose. The plicae are delicate and oblique. The body whorl contains about 16 oblique ribs that become in the lower part attenuate and then almost obsolete. The white aperture measures about 3/7 the total length. The outer lip is tenuous and widely sinuate. The smooth columella is almost upright. The broad siphonal canal is oblique.Melvill J.C. 1899.

Townsend, with descriptions of twenty-seven species.; The Annals and Magazine of Natural History, vol. 4, s. 7; London, 1899
The shell of L. eurina is unusual for the genus because it bears a distinct subsutural spiral fold, a feature somewhat reminiscent of that observed in Leucosyrinx thisbe. At the same time, the anal sinus is subsutural and occupies the entire subsutural ramp, which supports transferring the species from Comitas to Leucosyrinx.
Distribution This marine species occurs off Madagascar, Borneo and south of India at a depth of 878 m.
