56 6.0. SARS, (sem 
of metasome, and having the anterior edge considerably curved in the middle; 
Frontal spine (see Pl. I, fig. 2) rather large and freely projecting between 
the insertion of the eyes. The latter (ibid.) comparatively short, scarcely pro- 
jecting beyond the sides of the carapace, corneal part somewhat dilated and 
distinctly emarginated on the dorsal face. Superior antennæ with the pe- 
dunele (Pl. 1, fig. 3) of the usual somewhat club-shaped form, its last joint 
being rather dilated, and provided along the inner edge and the tip with a 
dense series of strong plumose setze, inner flagellum nearly 3 times as long 
as the peduncle and about half the length of the outer; male appendage — 
(see Pl. II, fig. 2) not fully as long as the peduncle and of the usual struc- 
ture. Inferior antenne (Pl. I, fig. 4) having the basal part produced at the 
outer corner to a strong triangular projection; scale very large, nearly twice 
the length of the peduncle of the superior antennæ, and oblong sublinear in 
form, fully 3 times as long as it is broad, outer edge perfectly straiglit and 
produced at the end to a strong spiniform projection, inner edge slightly 
arcuate in its proximal part, tip narrowly truncated and carrying about 14 
of the marginal setze, apical segment indicated by a slight suture cutting off 
a small part of the scale at the inner corner (see Pl. I, fig. 5). Pereiopoda 
(Pl. II, fig. 8) with the meral joint shorter than the ischial one and exhibit- | 
ing interiorly several fascicles of strong setze, tarsal part about the length of 
the meral joint and having the 2 middle articulations the largest, last arti- 
culation rather small. Outer ramus of 3" pair of pleopoda in male (Pl. II, 
fig. 10) scarcely more than half the length of the inner; Ak pair (Pl. II, 
fig. 11) reaching nearly to the tip of the telson, and having the exterior 
flagellum of the outer ramus about half as long as the stem. Telson (Pl. I, 
fig. 11, Pl. II, fig. 13) very much prolonged, considerably longer than the - 
last segment of metasome, and gradually tapering distally, lateral edges 
nearly straight, and each armed with about 20 spinules, the outermost of 
which is far removed from the tip, apical incision (see Pl. I, fig. 12, Pl. II, 
fig. 14) very small, narrowly rounded at the bottom, and armed with a small 
number (from 3 to 7) of dentiform projections, terminal lobes narrow conical 
and scarcely diverging, apical spine much stronger than the lateral ones. 
Inner lamella of uropoda (Pl. II, fig. 12) reaching but little beyond the telson, 
its base not very much tumefied and having the otolith comparatively small, 
inner edge armed, below the marginal setze, with about 10 slender spines, 
the outer 2 of which are placed at some distance from the others. Dorsal 
face of body ornamented (see Pl. I, fig. 1, Pl. II, fig. 1) with dendritic rami- 
fications, issuing from a number of pigmentary ‘centres placed in the usual 
manner. Length of adult female (including the antennal scales and caudal 
_ appendages) reaching 26 mm; that of male somewhat Jess.
