320 CRUSTACEA DRKDGED OFF POUT JACKSON, 



The final joint is sharply pointed and bears six spinules on its 

 inner margin and three on its outer distal half. 



The major flagellum of the inner antenna? consists of 25 articuli 

 and is clothed with hairs below. The inner flagellum is naked 

 and consists of 13 articuli. 



All the pereiopoda are clothed with scattered long stiff hairs. 



Chelipedes subequal. The merus-joint is trigonous, the inferior 

 angles carrying minute spinulse. There are no spines or 

 tubercles on its superior angle, but the line of junction with the 

 next joint bears a row of minute spines, below which and parallel 

 to it there is a well marked linear depression. 



The carpus is sub trigonous, and carries on its superior angle 

 three prominent forwardly directed teeth and a further small 

 tubercle at its proximal end. On the lower outer margin there 

 is a well marked row of small forwardly directed spinules, and 

 between this and the upper margin a further series of spinules 

 scarcely forming a line. 



The propodus, which has the palm somewliat swollen, has three 

 strong forwardly directed teeth on its upper margin, with a small 

 tubercle at its proximal end, as in the case of the carpus. Its 

 lower margin is denticulate. The outer surface of the palm on 

 the right hand (which is slightly the larger of the two) and of 

 the fingers carries a number of spinulous tubercles without any 

 definite linear arrangement. In the case of the left hand, how- 

 ever, they are on the palm arranged in four well defined rows. 



Fingers somewhat corneous at the tips and spoon-excavate^ 

 with a slight gap in their distal halves when closed. 



Of the ambulatory legs, the first pair are scarcely so long as 

 the second, which they closely resemble in their armature. The 

 merus, in common with the other joints, is somewhat flattened^ 

 and is thicker at its proximal than at its distal extremity. It is 

 fringed above with stiff setae, and bears a few scattered hairs on 

 its lower margin, but is without spinules or tubercles. 



The carpus carries a strong row of spines on its upper margin, 

 and two inconspicuous rows on its outer surface. The propodus 

 is also conspicuously spinose above, and there is a well defined
