CETJSTACEA OF THE MEEGTJI ARCHIPELAGO. 279 



little shorter ; they are ovate, ciliated along their internal 

 margins and at their rounded anterior ends, arid their external 

 margins terminate anteriorly in a small spinule. 



As in H. spinifrons, the outer maxillipeds are very elongate 

 and project much beyond the anteunal scales, the penulti- 

 mate joint of which is a little shorter than the terminal joint, 

 extending a little beyond it. The penultimate joint is armed 

 with a small spinule at its distal end ; along the upper margin 

 of the terminal joint (fig. 4) four or five similar spiuules are 

 observed, and four or five spinules occur also at the terminal, 

 obliquely truncated end of the joint. The last two joints are 

 ciliated, the cilise being partly arranged in transverse rows. 

 The equal, rather slender, anterior legs do not extend so much 

 forward as the outer maxillipeds, being shorter than them and 

 quite unarmed, although a little hairy. The meropodites are 

 slender and project as much forwards as the eyes ; the carpopo- 

 dites are a little longer than half the length of the meropodites, 

 and gradually appear a little thicker towards their distal ends. 

 The hands (the palm and the fingers taken together) are a little 

 longer than the carpopodites ; the fingers are shorter than the 

 palm, measuring two thirds of it, and are provided with some 

 small tufts of short hairs. 



The second legs are filiform and longer than the outer maxilli- 

 peds. The ischiopodites of these legs extend forwards nearly 

 to the anterior margin of the carapace ; the meropodites are a 

 little longer than the ischiopodites, and reach almost to the 

 distal end of the antennal scales or the middle of the penultimate 

 joint of the external maxillipeds. The carpopodites, which are 

 8| millim. long, are twice as long as the meropodites, and almost as 

 long as the carapace (the rostrum included) ', they are divided into 

 24 or 25 joints ; the terminal joint (fig. 5) is tvace as long as the 

 other joints, and presents a small tuft of hairs close to its articu- 

 lation with the hand. The other joints of the carpopodite are 

 naked. The hands (the palm + the fingers) are as long as the 

 three terminal joints of the carpopodite taken together ; the 

 palm is nearly as long as the terminal joint of the wrist ; and the 

 somewhat hairy fingers are a little shorter than the palm. 



The other legs are partly broken, so that I can only add 

 the following. The meropodites of the legs of the third paii 

 extend as much forward as those of the legs of the first pair, and 

 are armed with a small spinule near their distal ends. The pro-
