the outer margin and elsewhere long feathered setae occur, that are curved inward. Of the two 

 terminal joints one is 0,42 mm. long, a little shorter than the propodus and 3-times as long 

 as broad in the middle; the other joint is little more than half as long and both are beset and 

 fringed with long feathered setae. 



The external maxillipeds that project by their terminal joint beyond the antennal scale 

 and the peraeopods of the i*' and 2""^ pair resemble those of Stylod. Afnarynthis, but they 

 are not armed with small spines; like in this species the lower border of their joints 

 is fringed with the same long feathered hairs. The three posterior legs are more slender 

 than those of Stylod. Amarynthis. The merus of the 3'''* pair (Fig. iO(}), 2,2 mm. long and 0,2 i mm. 

 broad, is nearly ii-times as long as broad and armed with a spine near the distal extremity of 

 their lower margin, while nearly a dozen of simple hairs arc implanted on the ui:)per; the carpus 

 measures one-third the length of the merus and is 4-times as long as thick at the far end ; 

 the propodus, 1,7 mm. long and 0,175 ^im. broad, is one-fourth shorter than the merus and 

 lo-times as long as broad, 6 small spines occur on its posterior border, that increase in length 

 from the i*' to the 6"\ while there is a small spinule on the middle of the posterior margin of 

 the carpus; the dactylus (Fig. lOf), in Stylod. Amarynthis almost half as long as the propodus, 

 measures in this species but one-fifth of the latter, it is s'/o-times as long as broad and 

 armed with 3 spines posterior to the terminal claw. The legs of the 4"' pair resemble those 

 of the 3'''', those of the 5''^ pair, finally, are a little slenderer, but show for the rest also the same 

 characters, even as regards the armature of the dact\'li. 



The exopodite of the 2"'' pleopod is as long as the stalk or protopod, the endopodite 

 but little shorter, the slender stylamblys, finally, provided with distinct cincinnuli, is a little 

 longer than one-third of the endopodite.
