oae another. That which is seen in profile in Fig. 7, d, partially 

 encloses the other, c, which spreads out into a broad lamella 

 from a very narrow base at e. On the anterior edge of the proximal 

 protopodial lobe there are two rows of setae, one directed out- 

 wards, the other inwards ; the former are plumose, the latter 

 simple. The lobe a appears to be narrower in the figur? than it 

 really is, owing to foreshortening. 



Neither the second nor the third maxillipedes have an exopo- 

 dite. Both appendages are slender and pediform. In tne second 

 maxillipedes the carpus is long and much expanded ; the dactyl 

 ends in a spine. The third maxillipedes are very long and 

 slender, and are unarmed except for the spines on the dactyl. 

 The whole appendage is covered with long setae. There is a 

 small epipodite. 



In the female all five pairs of pereiopods are chelate, but the 

 last pair are not perfectly so, the dactyl being slightly longer 

 than the projecting part of the propodite. In the male the 

 first four pairs are chelate, but the fifth ends simply; In both 

 sexes the tips of the fingers in the first and second pereiopods 

 cross one another and are strongly curved. 



The first pereiopods or chelipeds are slightly longer than 

 the whole body from rostrum to tip of telson. They are 

 remarkably slender and feeble. The ischium is very narrow 

 at the proximal end, but expands distally, and this is also 

 true of the carpus. 



The merus is broad at the proximal end, narrows in the middle, 

 and then widens again. The palm of the propodite is the stoutest 

 part of the whole appendage, and is not so compressed as the 

 ischium and merus. The fingers are very long and thin, and 

 are sharply bent near the tip. The inner edge of each finger 

 is furnished with a row of small plates set obliquely, and over- 

 lapping one another. The merus bears one or two spines at 

 its upper distal end, and the carpus also has one in the same 

 position. Sometimes the propodite bears a spine opposite the 

 base of the dactyl. The upper margin of the merus is very 

 minutely spinulose. 



The other pereiopods are very much shorter than the first, 

 and diminish in size from the second to the fifth. 



The first pair of pleopods are very different in the two sexes. 

 Those of the female are fairly large and robust, passing the base 

 of the fourth pereiopods, and are heavily fringed with setae, 

 w^hich are of two kinds. There is a continuous fringe of slender 

 pinnate setae along each margin, and in addition to these there 

 is a mxUch smaller number of simple hairs, which are much longer 

 and thicker than the pinnate ones. The largest of all are to be 

 found in a little group of four or five situated at the base of the 

 distal joint. 



The first pleopods in the male are quite devoid of hairs, with 

 the exception of five or six on the proximal joint, and one at the 

 extreme tip. Near the extremit}^ there is a slight swelling on 

 the inner side, which bears a group of little hooks. The appen-
