spines on its inner margin ; it has other simple spines, but these are 

 less strongly developed than those on the corresponding joint of the 

 next two pairs. The third, fourth, and fifth peraeopods are stouter 

 than the second, subequal to one another in length and similar in 

 general appearance, but with certain differences, the fourth joint 

 being successively shorter but the fifth successively longer ; the fifth 

 also near the end of its inner margin has four groups of serrate 

 spines which are not represented on the two preceding pairs ; in all 

 three the finger has a group of spinules at the base of its acute 

 unguis, and on the proximal part of the inner margin 3 spines 

 successively larger ; on the third and fourth pairs these are preceded 

 by a very small spine, which in the fifth is perhaps hidden by the 

 last serrate group. 



In the uropods the broadly rounded apex of the exopod extends a 

 little beyond the narrowly rounded apex of the endopod and much 

 beyond the bifid, spine-including apex of the outer margin, from 

 which the diaeresis starts its devious course. 



The total length of the specimen was 67 mm., the carapace with 

 rostrum 30 mm., the telson 9 mm., the flagellum of the second 

 antennae about 85 mm. 



Locality. Off South Head, Tugela Eiver, from a depth of 12

Mr. Stanley Kemp has discussed this species so fully, with 

 the long list of synonyms which he assigns to it, that there 

 seems to be nothing left to say on the subject. Our small 

 South African specimen agrees with Bate's A. sica in the long 

 straight rostrum with 10 dorsal teeth of which the foremost is
