Type material. Type material of Daira depressa is considered lost (see Evans 1967). The type locality is the S.W. Pacific, west of Savaii, Samoa, 15 m, 15 March 1841. The description given by Dana (1853) is inadequate, and the figures too small, lacking in detail, to enable a determination of this species. Dana (1853) illustrates G1 and G2 with serrations on the posterior margin of the carpus, more typical of the genus Brachyscelus , but the description is more consistent with Lycaea , particularly in that Dana (1853) notes there are no serrations “on the palm”. Some species of Lycaea such as L. bovallii and L. vincentii have gnathopods with slight serrations on the posterior margin of the carpus but they are not as prominent as illustrated by Dana (1853).
