Diagnosis: Ovately fusiform shell, large for genus, attaining 100 + (?) mm in length, of 8,5 whorls; axial sculpture of 11 to 14 weakly folded ribs; color tannish white; spirally banded by irregular squarish blocks of brown below the suture and with 3 similar spiral bands on the body whorl; spirally threaded by 6 to 7 brown, strongly penciled, lines on the body whorl, with 1 to 3 similar spiral lines on the earlier post nuclear whorls; aperture whitish with yellowish buff submarginal callus within the outer lip.
Description: Shell ovately fusiform; 2,5 smooth nuclear whorls; 6 post nuclear whorls; first 3 post nuclear whorls with 14 well-defined axial costae; remaining post nuclear whorls with 11 loosely formed axial ribs; suture weakly defined; aperture elliptical, more than ½ the height of the shell; outer lip lacking marginal barbs, thickened internally by a submarginal lenticular callus; columella with 3 prominent adapical plications and 9 thread-like lirations, with the most adapically placed lira best developed; siphonal fasciole weak, anal sulcus shallow; operculum and radula unknown. Type locality: off Cabo Rojo, Puerto Rico, trawled in 500± m., ex-E. Flynn Ford coll., ex-Fred L. Leonard coll., 1981.
Holotype: AMNH no. 213575, from the type locality; height = 52 mm, width = 21.2 mm. Here illustrated, Figs. 1, 2 and 3.
Remarks: The color pattern approaches that of L, limata Hoerle and Vokes (1978, pl. 1, figs. 5a, 5b), but this smaller, more slender Miocene species has better developed costae, stronger and fewer columellar lirations, and possesses barbs on the outer lip.

Type locality: Trawled from 500 m, off Cabo Rojo, Puerto Rico. Range: Besides the holotype trawled off Cabo Rojo, southwest of Puerto Rico, some shells were also dredged in Venezuela and off Grenada at 150 m. This species seems to inhabit the deep waters off the whole the Caribbean.
Habitat: Unknown. All specimens have been fished in very deep water.
Description: Shell is solid, ovate fusiform, large for the genus, measuring up to 100 mm long. Protoconch smooth of two and a half whorls. Spire is moderately high. Teleoconch is of six slighty convex whorls, the first three sculptured with 14 well-defined axial costae and the remaining whorls with eleven low wide ribs. Aperture is narrow measuring more than 0.50 of the total length. Outer lip is slightly thickened, forming internally a submarginal callus. Columella is arched bearing three anterior prominent plaits followed adapically by numerous striations. Siphonal notch is very shallow and broad.
Background colour is beige, marked by 6-8 penciled brown spiral lines with four rows of well separated rectangular brown blotches: subsutural, on the mid body whorl which sometimes coalesce, and two
adjacent on the anterior part. Aperture is whitish. Animal: Not available for study. Most of the known specimens have been dead collected or taken crabbed in baited fish traps. Comparison: Its very specific pattern makes this species unmistakable, without possible confusion.
Remarks: It is another poorly known Lyria, very few specimens have been collected. Recently more specimens are brought up by fishermen operating in the Colombian Basin.
Because of its beautiful appearance and its extreme rarity, it is one of the most sought after Volutidae, together with Lyria cordis.
