on the pterygostomial regions and marked off anteriorly by a projecting acute tooth; the anterior 

 margin of the frame projects obtusely (Koelbel ascribes to it a triangular shape). An epistome is 

 distinct. The basal joint of the peduncle of the antennulae is globular, inflated, partly covered by 

 the front, and resembles that of Scopimera globosa. Koelbel pretends that the flagellum of the 

 antennae reaches about to the middle of the eye-stalk, bnt in my specimen it is not quite so long. 



The external maxillipeds in my specimen do not completely close the buccal cavern, though 

 they do so, according to Koelbel ; they are vaulted, but not quite so broad and operculiform 

 as in Scopimera globosa. The ischium is nearly quadrate, with parallel margins (fig. iti) and 

 near the anterior margin, that is trans verse and slightly concave, there is a row of cilia 

 in sino-le file across the ischium, which cilia are longest in the outer half. The merus, as 

 Koelbel rightly remarks, is only very slightly longer than the ischium ; the lateral margins 

 are convex, especially the inner, where in the middle a bunch of long, flexible and feathered 

 hairs projects. The flagellum again resembles that of Scopimera globosa: the thick carpus 

 occupies the whole, though very short, anterior margin of the merus, and bears a tuft of long, 

 feathered hairs near the distal end, so as to conceal almost wholly the next joint; similar 

 feathered hairs are inserted at the under margin of the carpus ; the terminal joint is twice the 

 length of the preceding, slender and gradually tapering. Both ischium and merus are covered 

 with widely separated and very short hairs at their outer surface. 



The chelipeds of the d 1 are remarkably long, owing to the great elongation of the arm 

 and wrist and to the bulky size of the palm. Koelbel mentions one specimen in which the 

 right chela is somewhat larger than the left, but in my specimen the chelae are equal in size. 

 The ischiopodite is unarmed, but the meropodite (arm) is sharply three-faced, with serrulate 

 borders and concave surfaces; the tympanum on the inner surface is, as Koelbel says, 

 broadly-oval and surrounded by a few long hairs; the outer tympanum is longer, half as long 

 as the meropodite, but narrower and less distinctly marked. The space not occupied by the 

 tympana is largely beset with granules, especially in the distal half of the inner surface, and 

 the whole arm is equal in length to the carapace. The carpopodite (wrist) is two-thirds the 

 length of the meropodite, flattened at inner and convex at outer surface, unarmed, except for 

 the fine serrulation of the borders, smooth, but granulate at outer surface, and the granules 

 are arranged in a' more or less distinct, oblique row, near the proximal half of the inner margin 

 of the wrist; this inner margin projects distally in a long prominence (before which a subdistal, 

 low tooth is present), articulating with a triangular tooth at the proximal end of the upper 

 border of the palm. The chela is very bulky, nearly equalling in length the distance between 

 the anterior angles of the carapace; the height of the palm is three-fourths its horizontal length, 

 which latter is about twice the length of the immobile finger. The outer surface of the palm 

 is somewhat flattened, the inner convex, both are very finely granulate, upper and under 

 border are sharp and crenulate, and the lower border passes straight to that of the immobile 

 finger; the upper part of the inner surface is more roughly granulate and these granules 

 extend upward as far as to the somewhat raised, sharply-cut superior edge, that terminates 

 proximally in a prominent, triangular tooth, with which the distal and superior tooth of the 

 wrist articulates. The fingers are very much gaping at their base, the fixed finger is perfectly
