According to Bate, the third maxillipeds have no exopod, 
but this is a mistake, due probably to the concealment of this 
narrow and not very elongate appendage behind the long 
antepenultimate joint of the maxilliped. In the first peraeopods 
the second and third joints have each an apical tooth. The 
sixth joint of these chelipeds is a little longer than the fifth. 
In the next pair the chela is very small, the slender delicate 
wrist fifteen-jointed. The three following pairs of peraeopods 
are nearly alike, but the last pair has to itself a graduated 
row of serrate spines leading to the base of the finger, and the 
finger’s inner margin carries six spines instead of five. In 
all three pairs the spine adjoining the nail is, except at the 
tip, much wider than the others. In addition to the three 
dorso-lateral pairs of spinules, the last of which is sub-apical, 
the telson has a larger apical pair with two intervening sete. 
Length—One specimen measured 63mm. in length; the 
other, far more slender, was only 40 mm. long. 
Locality —The larger specimen was taken 25 miles off 
Lion’s Head, between 131 and 136 fathoms, the smaller at 
*“* Gericke Point N. ? E., Knysna Heads E. 2 N.,” in a depth 
of 116 fathoms, on sand, shells and rock. Bate’s specimens 
were dredged at a depth of 150 fathoms, south of the Cape, 
and his description in general fully corresponds with the 
features of the new examples.
