on each propodua, they are unarmed, but there are short biushes 

 of setae overhanging the bases of the dactyli, and scattered bristles 

 on the carpus and propodus of each leg. 



The telson terminates in an acute spine, on either side of which 

 is a long internal and short external one, both of which are 

 movable. Two pairs of spinules are placed on the hinder half of 

 the upper surface. 



Oba. — This species is readily distinguished from its allies by 

 the position of the branchiostegal spine. From L. serenus it 

 further differs by having the second pair of legs shorter, and t lie 

 palm being much shorter than the carpus. The ambulatory legs 

 are also more slender than in that species. 



Hab. — Common in Port Jackson, where it is found on weedy 

 bottoms. It is also recorded by Miers 4 from King George's 

 Sound, S. W. Australia, and Tasmania. His specimens from 

 Ovalau. Fiji Group, probably do not belong to this species, and 

 those from Port Mode, Queensland, are possibly L. serenus. 

 Grant records it from Port Phillip, Victoria.

The surface of the whole body is roughened by very fine and 

 close-set lines which sometimes support a short but dense 

 pubescence. In large specimens these lines are also present on 

 the appendages, but in smaller ones they appear smooth. 



The carapace is armed with six large spines; one at the base 

 of the rostrum and a second behind it, a pair of supraocular and 

 a pair of antennal spines. The antero-lateral angle of the cara- 

 pace is also armed with a minute spinule. The rostrum reaches 

 a trifle beyond the scaphocerite and is inclined upwards towards 

 the end, but its extreme tip is directed downwards. The upper 

 margin bears two large teeth on the posterior half and five or six 

 smaller ones distal ly, the last being the tip of the rostrum. There 

 are eleven to thirteen teeth on the lower margin, which increase 

 in length backwards to the eighth, those following being shorter 

 and broader, and the last two recurved inwards.
