Gnathopod 1, 5th joint nearly z\ times as long as broad, 6th half breadth of 5th, with minute 7th joint; a few setae on anterior margin of 2nd joint and lower distal margin of 4th, the joints otherwise smooth; 2nd joint keeled near anterior margin, and 3rd and 4th on middle of outer surface. Gnathopod 2 similar, but 5th joint more slender, 6th lost. Peraeopod 1, 4th joint distally expanded, 5th expanded, ovate, the lower distal corner forming a roun


. Fig. 159. Lanceola remipes, General view, with apices of 4th and 6th joints of gnathopod 1, and 6th joint of peraeopod 1 further enlarged. Gnathopod 1, 5th joint nearly z\ times as long as broad, 6th half breadth of 5th, with minute 7th joint; a few setae on anterior margin of 2nd joint and lower distal margin of 4th, the joints otherwise smooth; 2nd joint keeled near anterior margin, and 3rd and 4th on middle of outer surface. Gnathopod 2 similar, but 5th joint more slender, 6th lost. Peraeopod 1, 4th joint distally expanded, 5th expanded, ovate, the lower distal corner forming a rounded flange on inner side, 6th lanceolate, 7th minute; 2nd joint keeled near front and hind margins, 3rd-6th keeled on middle of outer surface. Peraeopod 2 similar, 5th and 6th joints lost. Peraeopod 3, 2nd joint with lower hind corner forming a rounded flange on outside, 3rd with rounded flanges both inside and outside, 4th broadly expanded, following joints lost. Peraeopod 4, 2nd joint with small flange distally, 3rd with two flanges as in peraeopod 3, 4th and 5th subequal, 6th slightly shorter, with terminal retractile claw. Peraeopod 5 similar to, but slightly shorter than, 4th. Uropod 1, peduncle about four times as long as wide, with median longitudinal keel on lower surface, rami lost. Uropod 2 lost. Uropod 3, peduncle about twice as long as wide, with median longitudinal keel on upper surface, rami lost.
