witli the outer lobes broad, extending beyond the first abdominal segment and 

 terminating in points which are bent outwards, inner lobes veiy small and acute. 

 Abdomen comparatively short, not half as long as the cephalothorax ; genital 

 segment long, asymmetrical, the right side protruding more than the left; caudal 

 rami equal in length to the two last segments combined. Antennules short, 

 scarcely exceeding the length of the cephalothorax. Fifth pair of leg's with a 

 well developed exopodite, the terminal segment small but armed with seven 

 spines, endopodite almost reaching the end of the second segment of the exopo- 

 dite. Length, 3.2 mm. 



Male. Right antennule much swollen. Fifth pair of legs somewhat like 

 those of the preceding species; in the right leg the spines of the exopodite are 

 unequal, that of the second segment being longer than the first; endopodite 

 tapering to a point and bearing a small curved bristle near its base; basal 

 segment of the left leg produced inwardly to a point as in the preceding species, 

 endopodite extremely small. 



A single male specimen was bred from dried mud collected at Bringagee, 

 which closely resembled this species. In the formation of the fifth pair of legs 

 (PI. Iviii., figs. 7-9) the following diiferences were noted: the endopodite of the 

 right leg was tipped with a short but distinct denticle, and was also armed with a 

 straight upturned spine at the base, instead of the curved bristle, characteristic 

 of B. robusta; in the left leg, the inward projections of the basal segment and 

 the endopodite were of almost equal size and both rounded. Unfortunately no 

 female specimens were obtained, so that it is impossible to decide whether this 

 form is a variety of B. robusta or a distinct species.

Female. Cephalothorax robust, broadly oval, tapering slightly anteriorly, 

 lateral expansions of the last segment large, outer lobes extending almost to the 

 base of the first abdominal segment, tips pointed and directed outwards, inner 

 lobes very small. Abdomen short, genital segment short and broad, asymmetrical, 

 the right side bulging more than tl\e left, not very protuberant ventrally; second 

 segment very small; caudal rami and setae short. Antennules short, extending, 

 when reflexed, to the end of the cephalothorax. Fifth pair of legs with the curved 

 process, on the second segment of the exopodite, comparatively small, terminal 

 segment well developed and armed with seven spines. Length, 2.4 mm. 



Male. Right antennule strongly hinged, the penultimate segment produced 

 anteriorly. Fifth pair of legs of unusual form, the left leg with a small rounded 

 lobe on the inner side of the second basal segment, exopodite with the last seg- 

 ment bearing two spines, endopodite small and flattened; right leg with a com- 

 paratively small apical claw, which ends in two unequal points, endopodite long 

 and slender, extending beyond the second segment of the exopodite, its shape 

 peculiarly characteristic, being inwardly produced at the base, somewhat swollen 

 in the middle and blunt at the apex. 



This species has not before been recorded in New South Wales.
