Epistomal plate broad, rounded, almost circular. Md. abt. as in Menigrates (Sars 1895, p. no, PI. 38 fig. 1), but palp is longer, more slender, and is attached off the centre of the molar expansion, not proximally to the latter. On mx. 1 —2 and mxp. nothing special to observe; the form may be seen from the fig. P. 1 has coxal plate broad, roun- ded triangular; 2. joint abt. as long as the remaining part; metacarpus abt. 3/4 the length of carpus, obliquely truncate. P. 2 very slender, carpus i3/4time as long as metacarpus, not distally expanded; metacarpus in connection with the short heavy dactylus forms a chela; at the distal end 3(?) rows of strong setae. P. 3—p. 4 rather slender, dactyli abt. 2/3 as long as metacarpus; coxal plate of p. 4 rounded at the anterior ventral corner, not especially broad. Coxal plates of p. 5—p. 6 with hind corner a little deeper than broad, dactyli longer than half the length of metacarpus. Hind corners of 1. metasome segment rounded rectangular; 2. segment: almost rectangular; 3. segment triangular. 3. meta- some segment and 1. urosome segment have each a highly compressed, lobate rounded dorsal process, and 1. urosome segment has besides a deep impression. No dorsal process on 2.—3. urosome segments. Up. 1 has rami long, slender; outer ramus abt. as long as peduncle, inner ramus a little shorter. Up. 2 abt. as up. 1, but a little shorter and heavier. Up. 3 short and strong, without natatory setae; outer ramus abt. as long as peduncle, apical joint as long as the proximal; inner ramus a little shorter than outer ramus. Telson a trifle longer than peduncle of up. 3, with convex sides, cleft abt. to the base, with 2 pairs of dorsal spines. Remarks. According to the key in Stebbing 1906 (pp. 9—II) this species should Fig. 34. Lepidepecreopsis biloba. <J (). mm
