The head is, as in the female, mounted with a distinct frontal keel; the body is more slender than that of the female and even more so than that of the preceding species. The lateral corners are regularly rounded. The St. 2 of the caudal ramus is longer than the urosome. The antennulac extend about to the middle of the abdomen.

The head is, as in the female, mounted with a distinct frontal keel; the body is more slender than that of the female and even more so than that of the preceding species. The lateral corners are regularly rounded. The St. 2 of the caudal ramus is longer than the urosome. The antennulac extend about to the middle of the abdomen. The mouth-limbs are like those of the preceding species, but soft-skinned, short rounded appendages were observed in the Ei I—II of the max- illulae, and the appendages of the maxillae are better developed. The pes I shows the same difference as in U. minor, and the second basipodite of the fourth pair of legs is smooth. The fifth pair of legs differs from that of U. minor by a few features only; the Text-fig. 36. inner margin of the Ri dext. (fig. 2 c) has basally a distinct tooth, followed by a lamina Undeuchtzte major Giesbr. with a distinct process in the middle, in shape different from that of the preceding species; ftf. PesVsin. the outer margin of Re I dext. has a rather low keel, but no distinct teeth. The Re III sin. (fig. 2 d) differs by shorter terminal seta and by the different arrangement of the setae. The left endopodite is more slender (text-fig. 36). Y°. (St. V). Size of female from Thor St. 82 4-95mm.; anterior division 3-91 mm.; urosome 1-04 mm. The shape of body with the frontal keel is scarcely different from that of the adult female. The Se Re II in the first pair of legs is not shorter than in the female; the inner margin of the second basipodite in the fourth pair of legs is completely smooth. Occurrence.
