Aclis limata Dall, 1927: 69 .

Type material. Holotype (herein examined): USNM 108044 .

Type locality. USA: Georgia state: off Georgia, USFC sta. 2668; 30°58′30″N, 79°38′30″W, 538 m; Steamer Albatross col., 05/v/1886. The locality is not “off Fernandina” as stated in the original description (vide station number of the original label).

Material examined. The holotype.

Remarks. The present species has almost flat teleoconch whorls, a relatively thicker inner lip without an umbilical fissure, and the SEM images available for study indicate that the teleoconch does not present the microscopic spiral striae typical of Aclis . We propose a tentative classification in the genus Melanella Bowdich, 1822 despite uncertainties about the diagnosis of the latter genus ( Bouchet & Warén 1986; Souza & Pimenta 2019b).
