epimerals. These do not occupy the whole length of the under-margin 

 of the corresponding segments. 



The first pair of pereiopoda [PI. II. fig. 13] are shorter than the 

 second. The femur is broad, laminar, and carries two long, strong, bristles 

 at the anterior margin; it is more than twice as long as broad. The 

 genu is longer than the tibia, which carries four or five bristles at the 

 lower corner. The carpus is broad and long; at the lower, anterior 

 corner it carries a long spine-like bristle, nearly as long as the metacar- 

 pus, and some shorter ones at the hinder margin. The metacarpus 

 is shorter than the carpus (5: 6), carrying long hairs and bristles at 

 its end, which projects anteriorly a little over the base of the dacty- 

 lus. The dactylus is straight, sharp, longer than half the metacar- 

 pus (7: 10). 



The second jyair. The femur is thrice longer than broad, rectan- 

 gular, without hairs or bristles. The carpus is long and broad. The 

 metacarpus is narrow, slender, as long as the preceding joint; it carries 

 a bundle of short hairs at the end. The dactylus is half as long as the 

 metacarpus, feebly curved. The branchial sack is nearly as long as the 

 leg, the ovigerous lamella is quite as long as the leg and very broad, 

 irregularly fringed with long hairs. 



The third pair are stouter and provided with broader joints than 

 in M. LovÉNi. The femur is more than twice as long as broad. The 

 carpus is only a little longer than the metacarpus. 



The fourth^ fipl^^ (^i^d sixth 2^(iirs are very similar to the third. The 

 fifth pair are the longest. 



The seventh pair are shorter than the sixth, of the same length 

 as the first. 



The pleon is like that of M. Lovéni. 



The peduncles of the pleopoda are longer than the flagella. The 

 flagellum of the first pair consists of seven joints. 



The uropoda. The first pair reach far beyond the end of the se- 

 cond pair; the peduncle is even, a little shorter than the inner ramus. 

 The outer .ramus is straight, longer than half the interior; the inner 

 one is straight; both are serrated at the margins. The peduncle of the 

 second pair does not reach to the end of the peduncle of the preceding 

 pair. The peduncle of the second pair is shorter than the outer ramus. 

 The inner ramus is a third longer than the outer; both rami are ser- 

 rated along the inner margins. The peduncle of the third pair is only 

 a little shorter than the inner ramus and quite as long as the outer.
