The antennae have a slender spine at the outer base of the scale, which is narrow-oblong and about three fourths as long as the carapace (rostrum excluded);. W Fig. 66. Crangon abyssorum.

The maxillipeds are slender and exceed the scale by nearly half the length of the terminal segment. The first pair of feet do not reach the end of the scale. The merus has a small superior terminal spine. The manus widens a httle distally; its length is three times its width measured at the inner base of the spine; the dactylus is more longitudinal than transverse. The second and third pairs of feet are equally filiform and delicate; the second reaches to the middle or beyond the middle of the palm of the first; the third reaches beyond the antennal scale; the fourth pair also exceeds the scale; the fifth pair is a little shorter. In the male the sternum has a median carina with a small spine on each segment. The fifth segment of the abdomen has a low blunt carina; the sixth has two prominent d
