Upper antennae somewhat longer than two-thirds the length 

 of the body; peduncle short, extending to the extremity of the 

 penultimate peduncular joint of the lower; flagellum long and 

 slender; secondary appendage with about six articuli. Lower 

 antennae half as long as the upper, clothed with numerous 

 fascicles of very long setae; flagellum of subequal length to the 

 peduncle, and possessing very long setae. Gnathopoda long, 

 subequal in form, clothed with fascicles of long setae, the second 

 slightly longer and the hand rather more swollen; palm slightly 

 oblique, margin straight, entire, setose, defined by two spines, 

 one smaller than the other. Anterior two pairs of peraeopoda 

 short, succeeding three pairs long, the penultimate slightly the 

 longest. Terminal uropoda not long, peduncle short, inner ramus 

 lanceolate, and a very little shorter than the outer, its inner 

 margin fringed with long plumose setae, outer margin with six 

 fascicles of simple setae, and the extremity spinose and setose; 

 outer ramus parallel sided, fringed on the inner margin with 

 plumose setae, and bearing a spine near the extremity, outer 

 margin bearing fascicles of stout spines in four equidistant places, 

 and several long simple setae springing from their bases, the 

 extremity tipped with one very stout spine or rudimentary joint, 

 which is apically setose, and below its base are several spines and 

 setae. Telson cleft to the base, apeces rounded, its outer and 

 distal margins and dorsal surface with fascicles of stiff setae. 



Colour. — Spirit specimens uniformly yellowish. 



Length. — 13 mm. 



Occurrence. — Dandenong Creek, near Bayswater (collected by 

 Mr. J. Gabriel). 



Remarks. — I have only a few specimens of this interesting 

 form, and am not able to certainly define the sexual characters, 

 but of those received there is no apparent relative difference of 

 size in the .second pair of hands. I think it may safely be con- 

 sidei'ed a Garamarus. 



Supplementary Descriptiox. 



Upper Antennae. — The first joint of peduncle is stout, with only 

 a few setae at the distal extremity, the second slightly longer 

 and narrower, witli a few setae medianly and at the distal
