female, the strong incurved claw constituting the terminal 

 joint. The hand itself is somewhat compressed, oval 

 quadrangular in form, and projects at the end inside to a 

 well defined, claviform thumb, against which the terminal 

 claw admits of being impinged. The obtusely rounded tip 

 of the thumb is densely clothed with slender spikes, and 

 carries inside a small blade-like appendage, finely setous at 

 the end. Above the thumb, the inner edge of the hand 

 forms a distinct, obtusely angular prominence, as in the 

 male of Eulimnadia, and from inside the strongly dilated 

 base of the terminal claw a cylindrical, or somewhat clavi- 

 form appendage is seen to project, curving inwards, its 

 obtusely rounded extremity clothed with delicate sensory 

 hairs. In structure these 2 pairs of prehensile legs exactly 

 agree, except that in the 1st pair there is a setous 

 prominence issuing from the anterior face of the stem some- 

 what below the insertion of the epipodite, also found on 

 the same place in the female (see PI. 2, fig. 9). In the 2 

 succeeding pairs (PL 3, fig. 9) the stylet appended to the 

 penultimate joint of the stem is considerably longer than in 

 the female, and is divided into 2 segments, the distal one 

 being the shorter. The 10th and 11th pairs in the male do 

 not differ from the next preceding and succeeding pairs 

 in the form of the dorsal lappet of the exopodite (see 

 PI. 3, fig. 5). 



The caudal piece, too, is of quite a similar appearance 

 in the two sexes. 



Occurrence, — Of this interesting form some well- 

 preserved specimens, males and females were contained in 

 the collection, having been taken, according to the label, 

 from a pool on Green Point Common, near Cape Town, in 

 September 1897.
