Description of Two New Phyllopoda. 25 



transverse lines may be traced crossing the stem, thus 

 indicating a slight articulation of the antennulæ. 



The oars and oral parts do not exhibit any essential 

 différences from those parts in the female. 



The 2 anterior pairs of legs (PI. VI, figs. 1, 2, 5) are, 

 on the other hand, as above stated, of a very different 

 appearance. They are both very powerfully built, and 

 constructed in essentially the same manner, both having 

 their anterior face strongly curved. On the proximal 

 division of these legs, can be distinguished the same parts 

 as in the female, viz., inside at the base, a well-developed 

 coxal lobe, below which there are 2 or 3 rudimentary 

 endites, outside, the vesicular, upwards-pointing epipodite 

 and the exopodite, of which, however, only the dorsal and 

 ventral lappets are distinct, whereas the median part is 

 confluent with the stem. The distal division of the legs, 

 which is connected to the proximal one by a rather movable 

 articulation, is transformed into a rather complicated, sub- 

 chelate hand of a somewhat quadrangular shape, having 

 inside, about in the middle, a slight prominence (see figs. 

 4 and 6). At the end inside, the hand is produced to an 

 obtuse, thumb-like projection, against which the strongly 

 curved terminal claw admits of being impinged. To this 

 projection is appended a small oval lamella extending 

 towards the claw, and from the base of the latter another 

 very delicate, subcylindric appendage is seen to issue, 

 extending downwards. Of these parts, the claw would 

 seem to represent the modified 5th endite, whereas the 

 thumb may answer to the 4th endite in the female. The claw 

 is articulated to the hand by a rather broad base, to the 

 inner side of which a very strong muscle is seen to pass, 

 with ils fibres spread in a fan-like manner within the
