14 IVAR TRAGÂRDH, (Schwecl. Sudpolar-Exp. 



outer upper side near the joint provided with a complicated projection, directed obH- 

 quely backwards (Text-figs 24 and 25). Legs III and IV do not exhibit any peculiarities. 



The anibiilacres are of the shape, typical for the genus (Text-figs 20 & 21). 

 The claws are comparatively smaller and the secondary claws larger than for in- 

 stance in H. salimis Lab. 



The epistoiiia (Text-fig. 19) triangular, with long, sharply pointed, median 

 niucro; the edges are provided with about 10 pairs of small, sharp teeth. 



The liypostoma (Te.xt-fig. 23); the anterior pair of hypostomatic hairs larger 

 than the others. The maxillarv lobes simple, rather long and narrow, curved in- 

 wards. Stvli present, small, directed nearly perpendicularly inwards. 



The mandibles (PI. II, fig. 18). The lower and the upper jaw of the chela of 

 the same length and width; the lower one with one, the upper one with two sharp, 

 backwardly directed teeth, beside the terminal ones. Calear mandibnli of even 

 length throughout, curved slightly upwards, of e.xactly the same length as the chela. 



The uiaxilleiry palps (Te.xt-fig. 18) with 5 free joints; the first one narrow, 

 twice as long as broad, on the ventral side with two hairs inserted in very low 

 projections; the second, third and fourth joints of equal length, but the second broader, 

 nearly as broad as long; the third joint on the inner side provided with a strong, 

 serrated bristle; terminal joint small, only half as long and broad as the fourth, 

 with rounded top and richly provided with hairs. 



Female. 



Dorsal side like that of the male. 



Ventral side (PI. III. fig. 2). Tritosternnm shaped like that of the male. One 

 pair of jugular shields, a little broader than those of the male and with the thick 

 anterior edges falling off more abruptly towards the middle; without hairs. 



Sternal shield short, e.xtending backwards as far as to the middle of coxic III, 

 shorter than the genital shield. The front margin square, the antero-lateral angles 

 very long, extending in front of cox.t II as far as to their outer side; the hind 

 margin with a deep, semi-circular e.xcavation. 4 pairs of pointed bristles, much 

 larger than those of the male; the first one situated near the front margin, directed 

 backwards; the others situated near the sides and directed centripetally (towards 

 the middle), the second at a level with the middle af coxœ II, the third in the angle 

 between coxEe II and III, and the last pair in the postero-laleral angles of the shield. 



Parallel with the anterior margin of the sternal shield is a pair of light spots, 

 which, as in the case of the male, I am inclined to interpret as an indication of a 

 second pair of jugular shields. 



The genital shield is large, extending forwards nearly as far as to the front 

 margin of coxae III and backwards a little beyond coxae IV; the front margin is 

 semi-circular, the sides are subparallel, slightly concave; the hind margin almost
