Kdb. Clark Island, Port Jackson. 



TMs and the preceding are very variable species, the size of 

 the eyes and their degree of approximation above, the length of 

 the antennae and the form of the gnathopoda being aU subject to 

 considerable variations. 



Pherusa australis, sp. nov., Plate YII., fig. 1. 



Six anterior segments narrow; the four following broad. 

 Cephalon with a small rostrum. Superior antennae nearly as 

 long as the cephalon and pereion ; first two joints of the peduncle 

 stout ; third small, scarcely distinguishable from the articuli of 

 the flagellum ; flagellum slender, about twice as long as the 

 peduncle. Inferior antennae slightly longer than the superior 

 pair ; flagellum scarcely twice as long as the peduncle. Anterior 

 gnathopoda with the propodos ovate, the palm oblique, undefined, 

 armed with short setae. Posterior gnathopoda larger than the 

 anterior pair, the propodos ovate, dilated proximally, armed with 

 a few short setae and hairs towards the palmar border ; palm 

 oblique, undefined. Fifth pair of pereiopoda much longer than 

 the preceding pairs ; the dactylos elongate, slender, straight. 

 Last pair of pleopoda with the rami lanceolate, acute, each armed 

 on the inner border with three setae. Length 1/5 in. 



Hah. Botany Bay. 



Moera crassipes, sp. nov., Plate YII., fig. 2. 



Antennae sub-equal, nearly as long as the cephalon and pereion, 

 fringed below with long slender hairs. First pair of gnathopoda 

 with the carpus and propodos sub-equal, their upper border nearly 

 straight, the lower strongly convex. Posterior pair of gnathopoda 

 unequal, the right much larger than the left ; the palm deeply 

 concave, with a minute tooth about its middle, and defined with 

 a second, prominent, acute tooth. Fourth and fifth pairs of 

 pereiopoda very much longer and broader than the rest, the fourth 

 pair the broadest. Eami of last pair of pleopoda broad-lanceolatO;
