Shell relatively small for this family, though large for the genus; nearly smooth, imperforate and reaching 60 mm. (about 2,5 inches) in length. Whorls 8 and convex. Color ivory with numerous and irregular spiral bands of brownish spots and lines which are also in axial arrangement. Spire extended and produced at an angle of 48°. Aperture subelliptical. Outer lip slightly reflected. Parietal wall thinly glazed. Columella with two well developed plicae and one small one near the base and with several exceedingly fine, thread-like plicae above which extend over the parietal wall. Suture well indented. Sculpture consisting of very fine axial costae on the early whorls which arc absent on the later whorls which have only very fine growth lines. Protoconch broken. Operculum unknown.
Measurements of holotype: Height 60 mm., width 26 mm.
Type: Holotype, Museum of Comparative Zoology, no. 256494, from a fishtrap, Cabo Rojo, Prov. Pedernales, Republica Dominicana, Hispaniola. Collected by Bernardo Vega in December 1961.
Remarks: This species is related to Lyria beauii (Fischer and Bernardi) from Marie-Galante, Lesser Antilles, though it differs in several of its morphological characters from that species. Lyria vegai is smooth except for the first two whorls, and not axially ribbed throughout as in beauii; also the outer lip is more rounded. In addition, L. vegai has only the columellar plicae and 3 or 4 very small plicae at the upper parietal area, while beauii has a continuous series of small plicae which extend from the columellar area to nearly the uppermost portion of the parietal area.
Named for Dr. L. E. Vega of Ciudad Santo Domingo.

TYPE: Holotype, Museum of Comparative Zoology, Cam bridge, Massachusetts, No. 256494. TYPE LOCALITY: Cabo Rojo, Province of Pedernales, Dominican Republic, West Indies. RANGE: Known only from the type locality. HABITAT: The only known specimen came from a fish trap; depth unknown. DIMENSIONS: Holotype length, 60.0 mm; maximum diameter, 26.0 mm; aperture length, 37.0 mm. SHELL DESCRIPTION: Shell is rather large for the genus. It is subfusiform, with a high, convex spire. Protoconch is decollated. Teleoconch has eight convex whorls; the first two are sculptured with narrow axial ribs followed by very fine axial growth lines. Suture is well indented. Aperture is subovate, about five-eighths the total length of the shell. Outer lip is slightly reflected. Siphonal notch is wide; fasciole weak. The columella is weak, with one strong plait at the anterior end followed posteriorly by only four fine lirae. Base color is ivory with numerous, irregular spiral bands of brownish spots and lines which are in axial alignment. ANIMAL AND RADULA: Unknown. REMARKS: The species is known from a single shell collected without the animal. It appears to be closely related to Lyria beauii (Fischer and Bernardi, 1857) but differs in the following respects: Lyria vegai is axially ribbed on only the first two whorls, whereas beauii is axially ribbed throughout. Furthermore, vegai has only one strong, anterior columellar plait and four very fine lirae on the upper parietal area, as opposed to beauii, which has three strong, anterior columellar plaits and weaker folds that extend almost the entire length of the columella. This extremely rare taxon was named for Dr. L. E. Vega of Ciudad Santo Domingo.
