at the margins, whilst in the centre there is a long oval space, in 

 which the integument is not calcified. A similar, but smaller, 

 space occurs between it and the following segment. 



The second segment is narrow in the centre and expanded at 

 each side into two rounded lobes, which overlap the preceding 

 and succeeding segments. 



The third segment the longest and is sinuate posteriorly. 



T\i.e fourth is short and smooth. 



The fijth is narrow, and bears a strong median ridge. 



The sixth is somewhat long and exceedingly narrow, and is 

 hollowed on each side, thus throwing the centre up into a strong 

 ridge, which bifurcates at its posterior end. 



The telsoti is of the same length as the sixth segment, is 

 strongly ridged, and is fringed at the end with stiff hairs. 



The uropods are narrow and slightly longer than the telson, 

 and are fringed with strong hairs. 



The first antennae are robust and furnished with two flagella, 

 which reach only slightly beyond the squames of the second pair. 

 The basal joints are short, reaching little beyond the margin of 

 the carapace. 



The second atttennae are long, and furnished with short, broad 

 basal squames. 



The chelipedes are robust, and reach to the level of the distal 

 end of the antennal squamae ; they are furnished with a long, 

 curved dactylos, between the base of which and the short mobile 

 finger there is a short fringe of hair. The mobile finger is 

 situate about midway between the base of the dactylos and the 

 next joint. 



The secoftd pereiopod reach only to the carpus of the first pair, 

 and are clothed with hair. 



The third pair are of normal length and filiform. 



The fourth and fijth pairs are more robust, and with the third 

 pair terminate in a simple styliform dactylos.
