It is possible that these maybe subsequently developed ? 38 CAPRELLID^, CAPRELLID^ PROTO PEDATA. Specific character, Superior antennse nearly half the length of theanimal. Inferior antennse about half the length of the superior. First jmirof gnathopoda having the propodos triangular, palm oblique, armed withsmall spines, and defined by a sharp tooth.
