Eyes black, perhaps from formalin preservation. Color when alive.—Translucent. Ecology.—L. donaldsoni is a sand burrowing species. Remarks.—This new species differs from the only other species of the genus, L. fasciatus, by having fewer dorsal and anal rays, 19 to 21 dorsal and 23 to 26 anal instead of 25 or 26 dorsal and 27 to 29 anal rays.
