A small ”Latirus” from the West Indies was described and figured by MELVILL (1910) as Latirus ernesti. The description is based on a single empty shell, which is ochraceous in colour, with many white spiral lirae; the length measures 12 mm. Another small ”Latirus”, from Mujeres Island, Yucatan, Mexico, was described and figured by HAAS (1941, p. 167, pl. 1) as Latirus festivus. This is a brightly coloured shell, dark brown with yellow and purplish lirae. The holotype is a juvenile specimen, length 7 mm; one paratype measures 10¾ mm. According to HAAS, L. festivus is closely related to L. ernesti, but they differ in colour and in the number and width of the lirae.
