Scolecithrix valida 11. sp. Farran, pp. 55- 57. P'-V figs 14â15> pl-VI fig. 7. Description, f?. Size of specimen from Tlior St. 183 was 3-95 mm.; anterior division 31 mm.; iirosome 0-85 mm.

The body is more slender, and the liead less suddenly raised in lateral \ie\v than in S. obhtsi- froiis, but more distinctly so than in .S". globiceps (text-figs 62 aâb). The rostrum is most like that of the former species, with the basal part less enlarged and with fairly long, apparently undivided, filaments. The lateral corners are slightly produced and rounded (text-fig. 62 c). The genital somite is better produced below, and its receptaculum seminis appears more slender than in the preceding species; the comparative length between the abdominal somites and the furcal rami is 45, 28, 25, 9 and 17; the furcal rami are 1-5 as long as wide; along the hinder border of somites II âIV a marginal .seam with delicate serrations is observed. The antemmlae do not reach the end of the furca; the .segments 24â25 are fairh- well separated; "^sthetasken" are found in .segments 8^9, 12, 14 and ig; the segment 10 has a distinct seta, and a proximal seta is found in segments 12 â 14 18, and .sometimes in segment 15, but never in .segment 17; the Sp. of segment 24 is somewhat longer than segment 25.
