Original Description Shell a little rough, campanulate, with in- distinct collar, but pronounced lumbar stricture. Approximate proportions of the lengths of the segments 2 :5 :5; their breadths 1:4:5. Cephalis spherical, with about 25 well-separated circular pores, and bearing a thick three- or four-edged apical spine al- most half as long as the shell. Thorax conical in the apical section, inflated below, having closely-spaced circular pores 3-4 times as broad as the intervening bars: 12-15 pores on a half equator in the widest part of the thorax, and a similar number in a vertical series. Abdomen slightly inflated, its pores 1.5-2 times as large as those of the thorax, bearing the same relation to the intervening bars as those of the latter, and arranged in indefinite vertical series of 6-8 pores each. Outer coronal of the peristome not well- developed, consisting of 8-15 thorns arising from the abdomen above, or in the upper portion of, the peristomial lamella. Inner coronal with 9-11 somewhat convergent triangular teeth, arising from the lower edge of the peristomial lamella, which is approxi- mately as wide as an abdominal pore. Length of the horn 65-70 At;of the ceph- alis 24-26 /; of the thorax 60-65 /; of the abdomen 60-70 /; of the peristomial teeth 5-10 ,. Breadth of the cephalis 24-26 /; of the thorax 95-105 A; of the abdomen 115-130 /. This subspecies differs from Lampro- cyclas maritalis Haeckel, originally described from the central Pacific, in having more pores, more closely and regularly arranged, and thinner shell-wall. Also, the thorax is more definitely campanulate; although specimens of L. maritalis described by Haecker (1908, pp. 455, 456) from the northern Indian Ocean approximate it in this character.

Hays (1965, fig. 10) -"Its occurrence seems to be restricted to the cores in the warmest waters" north of the South Polar Front; at depth in cores V16-66 (42°39’ S., 45°40’ E., 2,996 m), V17-88 (57°02’ S., 74°29’ W., 4,064 m). Indian Ocean occurrences (fig. 39) .- L. maritalis maritalis is very sparsely distributed in low latitudes, but is fairly abundant (3% to 9% of the described population) south of 35° S (cf. L. maritalis polypora, discussion, p.77).
