Lacrie's description and exact figures are quite sufficient to recognize this species, but 

 the following remarks may be of some use: 



The carapace is practically smooth and polished, but there is a stripe of closely-set 

 granules along the lateral margins; on the cardiac region three small depressions are found, 

 placed in an aequilateral triangle. The lateral margins are somewhat more divergent backward 

 than is shown in Laurie's figure; they are. together with the anterior margin, fringed with 

 rather stift" setae. The orbits are visible from above and completely filled by the firmly-fixed 

 eye-stalks; these eye-stalks are granulate above, like the lateral margins of the carapace, but 

 completely smooth ventrally, the two parts are separated by a sharpened edge, along which 

 the transverse row of setae passes across orbits and front. The fronto- orbital distance is more 

 than one-half the greatest breadth of the carapace, but to a lesser degree in my specimen than 

 in Laurie's. Only in ventral view of the animal a small, but very distinct, black spot of pigment, 

 near the end of the eye-stalk, and concealed beneath the transverse row of setae, denotes an 

 eye; it has been accurately figured in L.aurie's figure iia. 



The antennules are very small, somewhat obliquely folded beneath the vertically-deflexed, 

 deeply-bilobed front. The antennae are remarkably long (nearly half as long as 

 the carapace), very stout, the flagellum (fig. 2a) consists of ten j oin ts, the 

 second of which is by far the longest; all are provided with very long, 

 feathered hairs, except at the ventral surface; these hairs give the antennae a superfical 

 resemblance to little fir-trees. The epistome is distinct, its free edge prominent and entire. The 

 lateral margins of the buccal cavity distinctly converge backward and so do the external 

 maxillipeds ; the antero-external angle of the merus is produced laterally and the anterior margin 

 is somewhat concave (not convex as in L.\urie's figure), the exognath is half as broad as the ischium. 



The chelipeds are rather small, subequal; meropodite short, unarmed at upper border; 

 upper surface of wrist roughened by depressed granules, especially near the produced inner 

 angle of the wrist; similar granules are found at outer surface of palm, e.xcept in the central 

 portion, which is smooth; upper border of palm sharpened; under border of chela forming a 

 convex line, carinate along fixed finger and distal part of palm ; height of palm somewhat less 

 than horizontal length and about equal to length of fingers ; fixed finger very high at base, 

 largely compressed, provided with 3 — 4 obtuse teeth at inner margin ; movable finger not flattened, 

 nearly unarmed at inner margin-, both fingers of a light sepia colour, darker than the palm. 



Walking legs fringed with silky setae, like those of the carapace, but longer, especially 

 in the case of the last pair; all pairs are subequal in length. The dactyli are not flattened, 

 those of the first and second pair are the longest ^). The propodites are unusually short, the 

 posterior margin being much convex. The meropodites are unarmed; those of the fourth pair 

 the broadest, but rapidly narrowing distally, in their proximal part the meropodites of this pair 

 are halt as broad as long, as has been accurately depicted in Laurie's figure. 



The abdomen of the cf is narrow ; all segments are distinct ; the first segment attains 

 only one-fourth of the breadth of the last sternal segment; the third segment is little produced 



l) Miss Rathbi'X remarks: "second leg similar to the third, but slightly longer, the additional length being in the dactyl".
