1038 NOTES ON A FEW AUSTRALIAN EDRIOPIITHALMATA, 



narrower, third half as long as the second, flagelluni considerably 

 longer than the peduncle, secondary ai)pendage 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 sette, carpus considerably longer than 

 propodos, inferior edge bordered with many long sette arranged in 

 short transverse rows, many of the shorter setae serrated, small 

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

 corner a row of stout serrated seta?, the integument near the base 

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

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

 broad, narrower at base than at distal end, long setse 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 

 seiiated seta2 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 setje on posterior margin, two rows 

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

 and blunt, truncate at end. 



Female. — Differs fi-om 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 

 margins and on centre ; propodos ovate, palm oblique, not defined, 

 transverse rows of setge on both margins ; dactylos long, acutely 

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

 of the male.
