small, shorter than the blunt extremity of the lamella. Antennal flagellum almost twice as 

 long as the body. 



In the left mandible (Fig. 25 c) the cutting-edge of the incisor process is armed with six 

 acute teeth, of which the first, at the opposite side of the pal]), is a little larger than the 2 nd ; 

 the 2 nd and four following slightly increase in size, so that tin- 6 th , at the same side as the 

 palp, appears as large as the first. The outer margin of the truncate extremity of the molar 

 process bears three obtuse, subequal teeth, while the brown inner margin is entire. In the right 

 mandible (Fig. 25^, 25 c) the incisor process bears four or five teeth, three or four of which are 

 of equal size, while the fourth or fifth, at the side of the palp, is twice as large as the others. 

 The outer margin of the truncate extremity of the molar process bears 6 or 7 blunt teeth oi 

 unequal size, at the inner side one observes a brown coloured, concave portion, the posterior 

 obtuse angle of which is dentiform, while another smaller, obtuse tooth occurs posterior to it. 

 The i st or basal joint of the 3-jointed palp is produced posteriorly and distally into a truncate 

 or obtuse process, 2 nd joint slightly shorter than i st , 3 rd as long as i st and 2 nd taken together, 

 flattenecl, not narrowing but truncate distally and almost 3-times as long as broad. 



Of the two inner distal lobes of the 2 nd maxilla (Fig. 25/), that project far bevond 

 the basal lobe, the anterior is rounded and one and a half as broad as the posterior; posterior 

 lobe of the exopodite rounded. Seventh joint of 2 nd maxillipeds (Fig. 25^) applied as a strip 

 to the 6 th , nearly three times as broad as long. The external maxillipedes réach, both in the 

 male and in the female, by their terminal joint beyond the antennal scale; terminal joint about 

 1 / 6 shorter than the penultimate, that measures two-thirds of the antepenultimate; exopodite half 

 as long as the latter. 



Unfortunately in the single male the legs are wanting or incomplete. In the female the 

 legs show the following characters and measurements. The legs of the i st pair reach by two- 

 thirds of their carpi beyond the antennal scale; their terminal joints, which at their subacute 

 extremity show no tracé of a microscopical chela, measure one-third of the carpi. The legs of 

 the 2 nd pair are very slender, equal and reach by the chela and half the carpus or a 

 little more beyond the antennal scale; terminal joint of the carpus, which is nearly as long 

 as that of the i st pair, almost as long as the three preceding joints combined and one-hfth 

 shorter than the chela; chela 1 j u of the carpus, fingers as long as the palm. The three 

 posterior legs are also very long and slender; those of the 3 rd pair extend by the three 

 last joints and a small part (about */,,) of the merus beyond the antennal scale, those of the 

 4 th only by the three terminal joints, those of the 5 th pair by the two last joints and almost 

 the whole length ( 9 / 10 ) of the carpus. The three legs, however, slightly increase in length from 

 the 3 ld to the 5 th , though the meri become gradually a little shorter in the same succession, 

 because the carpi and the propodi distinctly increase in length. The dactyli of the 3 rd pair 

 measure almost one-third, those of the 4 th about one-fifth, those of the 5 th one-sixth of the 

 propodi ; the dactyli are flattened, narrow, lanceolate, and nearly straight. As results from the 

 Table the proportions between the joints of these legs vary, however, rather much : so e. g. in 

 N° 2 and X" 8 the propodi of the 5 th pair are almost twice as long as those of the 3 rd , in 

 X" 3 and X" 6 only one and a half.
