Victorian Decapod Crustacea. 63 



The hand is large, smooth and flattened, with a few irregular 

 punctations on its lower outer surface. Two large depressions 

 are situated on either side of the articulation of the mobile finger, 

 and are filled with a long, coarse brush of hairs. The upper 

 margin is strongly keeled, the keel is clothed with longitudinal 

 rows of scattered hairs and ends somewhat abruptly at its distal 

 extremity in an acute flattened tooth. The lower margin is 

 armed posteriorly with a series of small, flat, forwardly-projecting 

 teeth, and is somewhat hairy. Its lower distal extremity is 

 extended into a strong, short, rudimentary, inferior finger, which 

 is toothed on its upper margin for its posterior half. The mobile 

 finger is three-fourths as long as the palm. It is slightly curved, 

 flattened and somewhat excavate above, and is triangular in 

 section, with the upper edges strongly denticulate and fringed 

 on the sides with strong hairs, ending in a smooth horny point. 



The second leg, which is monodactyle, is somewhat larger than 

 the succeeding ones, and is flattened. The arm is clothed with a 

 row of long coarse ciliated hairs. The wrist has its lower distal 

 margin ending in a small tooth, and with the hand and dactylos, 

 is fringed with long hairs. The last two joints are without teeth. 



The third and fourth legs are more slender than the second, 

 they are not armed with spines or teeth, nor so heavily clothed 

 with hairs. 



The fifth leg is slender and subchelate, the immobile finger 

 being short spoon-excavate and finely toothed along its upper 

 margin. The last two joints are densely clothed with long hairs, 

 which somewhat conceal the subcheliform structure of the legs. 



The telson is broadly rounded, medially sulcate, and fringed 

 with stifi" hairs. 



Uropods. — The uropods are furnished with a bifurcating median 

 ridge, having a sharp tooth at the point of bifurcation and a 

 similar tooth behind it on the pi'eceding joint. The endopod 

 bears a strong rib on its upper margin, and also a single median 

 rib. Both are strongly fringed with hairs. 



Colour. — Cream-yellow shading to pale pink.
