COPEPODA 



Le of which has 5 setae, while its Li has 7 setae. The maxillulae are scarcely different from those 

 described in E. curticauda; the maxillae agree in general shape (cf. fig. 3!! PI. IV), but the setae of the 

 four proximal lobes are poorly developed, while the fifth lobe has a long, soft, somewhat contorted sensory 

 seta in addition to one fairly slender and one very short of usual structure; the maxillipeds are as 

 usual more slender than in the female. 



The first pair of legs is as usual well distinguished from that of the female ; the first and 



the second outer segments are marked off from each other by a small incision, proximally to which the 



short, at base swollen, Se is found; the Se of Re II is short and moderately slender; the position of 



b the glandular pores in the outer margin 



of Re II and III is as in the female. The 

 third pair of legs differs by the better 

 developed accessory tooth of the Se Ri 

 I, and the fourth pair by the smooth 

 inner margin of the second basipodite. 

 The fifth pair of legs is much longer 

 than the abdomen, and extends almost 

 to the end of the furcal setae; both 

 legs are very similar to those of E. mes- 

 sinensis (text-figs 32 c d); the processes 

 on the margins of the rami of the right 

 leg are slightly different from those of 

 the mentioned species. The right endo-

podite seems to be wanting; the right 

 exopodite is terminated by three some- 

 what hirsute processes (cf. text-fig. 32 d), 

 of which the first is hook-shaped with 

 three teeth, the second is flat and rounded, while the third one is slightly hook-shaped without serrations. 

 Y n (St. V). Size of female from Thor St. 88 478 mm. ; anterior division 3-91 mm. ; urosome 0-87 mm. 

 The shape of the body is practically like that of the adult female with the usual differences 

 in the shape of the abdomen ; triangular teeth are found along the hinder margin of somites II III. 

 The only difference of importance which was observed in the mouth appendages was found in the 

 antennae, which in the female as well as in the male is like that of the adxilt female, but in Le Ri 

 only 6 setae are found and in Li 7- The Se of Ri I is blunt, and only slightly prominent in the 

 second pair of legs, and its accessory tooth is almost obsolete. The inner margin of the second basi- 

 podite in the fourth pair of legs is smooth in the male as well as in the female. The fifth pair of 

 legs of the male shows (text-fig. 32 f) on the one side a distinct similarity to that of E. messinensis, but 

 is on the other side distinctly different, f. inst by the short rounded left endopodite.
