This species was instituted by Zimmer for two specimens taken in a vertical haul (3000-0) m. off the west of the Cape of Good Hope. The types consisted of an adult <3 of 9 mm. and an immature female. Specimens of the same size in the Discovery material agree so closely with Zimmer's description and figures, that I have no hesitation in referring them to his species. The only difference I can find is in the largest specimens of the Discovery material, where the anterior margin of the carapace extends farther forward than in Zimmer's figure and partially covers the bases of the eyestalks. In Fig. 30 I have copied some of Zimmer's figures and placed them beside corresponding figures of an adult female from station 254. A comparison shows not only how closely they resemble one another, but also the slight difference which I have mentioned. In his description Zimmer noted a single blunt spine on the inner margin of the endopod of the uropod at the distal end of the statocyst, but did not figure it. I have found this spine to be present in all my specimens, but it is by no means easy to see unless the appendage is dissected, for it is blunt and lies on the ventral side of the endopod a little way in from the margin, barely projecting at all (Fig. 30 B). The finger-like process on the inner margin of the eye is very small in younger animals, but in adults of both sexes it lengthens and curves outward in front of the cornea (Fig. 30 A). Nouvel (1943, p. 75) doubtfully referred a damaged female specimen captured off the Azores in a vertical haul, 2500-0 m., to this species. He pointed out that the rostral plate formed a more obtuse angle than in Zimmer's types and that the rostrum was less marked. He also noted that the scale was somewhat narrower than in L. capensis and that the spine on the outer margin was more acute. In his review of the M
