have been broken off, but their insertions are very distinct. 

 In the first scutum one of these projecting setae has been 

 preserved; it is somewhat longer than the breadth of the 

 proximal antennal joints, and the corresponding setjB on 

 the second scutum were certainly at least as long. Most 

 of the other marginal sette on the second scutum are also 

 wanting, but judging from their small areas of insertion none 

 of them were more than moderately developed. On the 

 third, fifth, sixth, and eighth scuta the large insertions of 

 the antero-lateral setee are plainly seen; in the other scuta 

 they are wanting, as in S. oriental is, etc. The penulti- 

 mate scutum is posteriorly somewhat emarginate, nearly 

 angularly concave in the median line. 



Legs. — The last pair and the left leg of the eleventh pair 

 are Avanting ; the right leg of the eleventh pair differs 

 scarcely from the tenth pair, of which the left leg has been 

 drawn (fig. 2 a), and is described here. The tarsus is four 

 and a half times longer than deep. The metatarsus with 

 four, the tarsus with five sette in the anterior dorsal I'ow ; 

 these setse differ but little in length from each other, and 

 none of them are quite half as long as the breadth of the 

 metatarsus; the most distal dorsal seta on the tibia is slightly 

 longer than those on the metatarsus. The anterior claw 

 (fig. 2 h) is medium sized, rather curved, and distally some- 

 what elongate ; the posterior claw is slender, considerably 

 curved, and only three fifths as long as the other; a front 

 seta is not conspicuous. The exopod is scarcely two thirds 

 as long as the dc])th of the metatarsus. The first pair of 

 legs with the anterior claw (fig. 2 c) very long and somewhat 

 curved ; the posterior claw is short, not reaching the middle 

 of the other ; the seta not longer than the short claw, and 

 moderately slender. 



Cerci (fig. 2 fZ). — A little more than four times longer 

 than deep, set with a rather good number of stiff seta;, 

 gradually increasing considerably in length from the base 

 outwards, and the most distal ones are about two thirds as 

 long as the depth of the cerci. The terminal area about as
