1038 NOTES ON A FEW AUSTRALIAN EDRI0PHTHALMATA, 



narrower, third half as long as the second, flagellum considerably- 

 longer than the peduncle, secondary appendage of four articuli. 

 Lower antennae longer than peduncle of upper, flagellum longer 

 than last joint of peduncle. 



Anterior gnathopoda small, meros thickly covered on inferior 

 edge with very furry setae, carpus considerably lunger than 

 propodos, inferior edge bordered with many long setae arranged in 

 short transverse rows, many of the shorter seta? serrated, small 

 tufts of setae along the centre of the joint and at antero-distal 

 corner a row of stout serrated setae, the integument near the base 

 of these being thickly covered with short furiy setae similar to those 

 on meros ; propodos nearly quadrangular, about twice as long as 

 broad, narrower at base than at distal end, long setae at base of 

 the dactylos and a few in small scattered tufts over the joint ; 

 palm almost transverse, bordered towards the end by 4-5 short 

 seriated setae like those at end of carpus. 



Second gnathopoda large, right and left equal in size, meros 

 produced infero-distally into a short pointed process ; carpus sub- 

 triangular, short ; propodos about four times as long as carpus, 

 quadrangular, greatest breadth about half the length, upper and 

 lower borders nearly straight ; palm slightly oblique, defined by a 

 short acute tooth and having a blunt prominence in the centre, 

 bordered with a few stout setae, whole propodos thickly covered 

 with transverse rows of long fine hairs, chiefly at upper and lower 

 margins but with some also in the centre; carpus having two 

 similar rows on anterior margin and 4-5 densely packed transverse 

 rows of short stouter serrated setae on posterior margin, two rows 

 of long setae in centre at base of propodos. Dactylos very short 

 and blunt, truncate at end. 



Female. — Differs from the above in having the second gnathopoda 

 much smaller, right and left being equal in size as in the male ; 

 carpus three-fourths as long as propodos, subtriangular, thickly 

 covered with transverse rows of setae on anterior and posterior 

 nun gins and on centre ; propodos ovate, palm oblique, not defined, 

 transverse rows of setae on Loth margins ; dactylos long, acutely 

 pointed. The first pair of gnathopoda is precisely the same as that 

 of the male.
