The epistome is large, with a small median anterior 

 projection. 



The mandibles are rather slender with large palps, 

 incisory processes strongly dentate, spine row and secondary 

 plate of left mandible obscure, molar process small, but pro- 

 jecting as far as the incisory process. 



Maxillipeds narrow, with lobes of palps small and the 

 fringes of these scanty. 



First gnathopods the smallest of the legs, joints very 

 sparingly spined ; dactyli small. 



Second gnathopods the longest of the legs and not differ- 

 ing much in robustness from those which follow, the second, 

 third, fourth, and fifth joints not differing much in length 

 and covered on their sides, presented inwards with dense, 

 very fine hair ; there is also a litle tuft of similar hairs near 

 the distal end of the first joint ; dactyli small, each with two 

 very small claws; spines are absent. 



The third pair of legs are longer than those which follow 

 and little less robust, also strongly ciliated. In the four 

 following pairs the joints are flattened on their surfaces, pre- 

 sented inwards, and are densely furred ; the dactyli are 

 short with large curved terminal claws, each showing a some- 

 what subchelate arrangement with the subterminal claw. 



Sternal filaments short, stout, and partially cylindrical. 



The uropods are broadly lamellar extending considerably 

 beyond the end of the abdomen, especially the outer rami, 

 the shape of which is irregularly accuminate; the inner rami 

 are truncate. 



One male specimen from Victor Harbour. 



I have specimens of an Amphoroidea from Tasmania 

 which agree well with M. Edwards' figure of A. typa, except 

 that the posterior notch is lunate as in the present species. 

 They, however, differ from it in having a narrower body, in 

 having the basal antennular joints larger and more project- 

 ing, their combined anterior margins being more arcuate, 

 with the inner margins nearly parallel, in the legs being 

 destitute of fur, in there being a greater distinction in size 

 between the first three pairs of legs and the following ones, 

 and in the uropods being somewhat slenderer. There are 

 four females, none of which show signs of brood. 



Group Platybranchiat\e. 



Genus Paracassidina, n. gen. 



Paracassidina pectinata, n. sp. PI. xxiii. 



The body is ovate, smooth, moderately convex, with 



epimera spread outwards, bearing a margin fringe which is 



short, dense, and with a few longer hairs projecting.
