A strong antennal ;â -'â '' 11111, TT Fig. 48. Spirontocaris macrophthalma. Station 3076. a. Side view, t (X z)- b. Dorsal view of anterior portion, 8 (X i). spine on the anterior margin, no supraorbital nor pterygostomian spine; antero-lateral angle sharp. Eyes large, pyriform; corneae extending on the inner side almost to the base of the peduncle. Eyes reaching two thirds the length of the first antennular segment; this segment is twice as long as the second, and the second three times as long as the third; the second and third are each provided with a terminal spine; the peduncle does not reach the end of the rostrum; the thickened part of the outer flagellum exceeds by half its length the antennal scale; inner flagellum half again as long as outer; the basal scale does not quite reach the end of the first seg- ment ; it has a strong lobe on its proximal outer margin. The peduncle of the antennae extends to the end of the second segment of the anten- nulae and the middle of the scale; the flagellum is one and a third times the length of the body. The blade of the scale exceeds the spine con- siderably, and is most advanced toward its inner margin. The outer maxillipeds are slender and reach midway between the end of the antennal peduncle and the end of the scale. The first pair of feet reach just beyond the base of the scale; the second pair just beyond the end of the scale; of the carpal joints, the second is greater than the first, the first plus the second equals the third, the fourth equals the seventh, the fifth is greater than the sixth, the fifth plus the sixth exceeds a little the seventh. The last three pairs of feet are long, fragile, and unarmed;
