Observations. This very characteristic species may be easily recognised among the 

 different species of Pallene by the form of the proboscis and cephalothoracic segment, by the 

 shape of the denticulate spines of the ovigerous legs, by the presence of a claw at the end of 

 the ovigerous legs, and finally by the absence of auxiliary claws ai the end of the legs".

Off the entrance to Port Philip (Melbourne, Australia). 38 fm. 



„Body highly concentrated, rather disciform. Proboscis conical, cephalothoracic segment 

 comparatively long. Ovigerous legs with denticulate spines, but without a claw. Legs without 

 auxiliary claws. Oculiferous tubercle conical, elevated. Rudiments of palpi in the form of knobs. 

 Total length = 1,8. 



Observations. This species is in all probability nearly allied to Pallate longiceps Bhm, 

 from Japan".

,The body of this species is rather short and thick, the intersegmental lines very distinct, 

 the lateral processes closely approximated to one another. The proboscis with the neck is a 

 little shorter than the body proper; the length and breadth of the segments of the body are 

 nearly equal. The proboscis is as broad as the body behind, conical, coming gradually to a 

 point in front. The abdomen is short, shield-shaped, slightly notched in the middle behind. The 

 first pair of appendages are very large; more than twice as long as the proboscis; the first 

 joint is thick, a little narrower at the proximal than at the distal end, as long as the proboscis; 

 the penultimate joint is very large, .somewhat longer than broad, laterally compressed; its digital 

 process is stout, and presents a rounded lobe towards the middle of its inner border; the last 

 joint (dactylus) is of a similar form to the digital process of the preceding and has a similar 

 rounded lobe on its inner border. The third pair of appendages have the four basal joints stout, 

 the third and fourth together, narrower, curved, and provided with a conical process standing 

 out at right angles at its distal end ; the sixth joint is about a fifth of the length of the fifth ; 

 the following four joints are each ornamented with a small number — half-a-dozen or fewer — 

 of compound setae ; the seventh and eighth are longer than the ninth and tenth ; the last is 

 succeeded by a long pointed claw. In the following pairs of appendages the basal joint is equal 

 in length to tlie lateral process ; the second joint is about twice the length of the first, constricted 

 at the proximal end ; the third joint is about the size of the first ; the fourth, fifth and sixth 

 joints are nearly equal, the fifth being the smallest; each of them presents two constrictions ;
