fled and bears a gill and leaf. The basipodite is firmly ankylosed 

 with the ischiopodite, the two together being about as long again as 

 the c'oxopodite. The meropodite in this limb is the longest segment 

 the carpopodite is short, the propodite long bearing a few setse on 

 the inner surface of its distal extremity. The dactylopodite forms a 

 sharp claw or talon and is almost covered with setse. 



The second leg is longer and more slender, but otherwise resembles 

 •the first. - 



The third is the longest of the legs. There are fewer hairs on the 

 propodite. On the dactylopodite the hairs form two lateral fringes. 

 In the female the ventral surface of the coxopodite close to the 

 sternal articulation shows a small pin-hole which is the orifice of the 

 .oviduct. . , . . 



The fourth resembles the preceding. 

 '. The fifth differs from the other . legs in having no epipodite and 

 consequently no gill. In the male the ventral surface of the coxo- 

 podite has a large opening for the vas deferens. The propodite is 

 about the same length as the meropodite. The dactylopodite is claw- 

 like. 



In the female, the propodite is the longest segment and the inner 



angle of its distal end is prolonged 

 to form a spine against which the 

 dactylopodite can be opposed so as tc 

 form a .small pincer or forceps. The 

 dactylopodite is somewhat bifid having 

 a large outer claw and a short inner one 

 which forms the outer blade of the 

 forceps. 



This is the only representative ii\ 

 Palinurus of the powerful forceps so 

 characteristic of Cray-fish, Lobsters, 

 Prawns and Crabs, and it is worthy of 

 note that while all these Crustaceans 

 have the anterior walking legs chelate, 

 it is only the posterior limb of the
