18 Annals of the South African Museum. 



maxillae have a small apical joint, longer than broad, tipped with a. 

 seta; the preceding joint has very sinuous margins, with a pellucid 

 transverse band near the apex, behind which the surface has several 

 spines, and the inner margin develops a strong tooth. Second 

 maxillipeds with terminal joint longer than the penultimate, exopod 

 very elongate. Third maxillipeds more slender than the first 

 peraeopods, the long exopod reaching the end of the fifth joint, 

 the epipod strongly furcate. The first peraeopods have the second 

 joint produced into a strong tooth, the short exopod strongly setose, 

 the fifth joint not longer than the chela, in which the palm is much 

 shorter than the fingers ; in these the tips are rounded, the confront- 

 ing margins as usual microscopically denticulate ; the brushes of 

 small serrate setae are present distally on the fifth and proximally 

 on the sixth joint. In the much longer second peraeopods, similar 

 to the first as to the tooth and exopod, these brushes are not present, 

 and the fifth joint is much longer than the chela. In the third 

 peraeopods, which are much longer than the second, the fifth joint 

 is twice the length of the chela and the palm is subequal in length 

 to the fingers. The fifth peraeopod is rather shorter than the third, 

 rather more slender than the fourth but considerably longer, and 

 apparently unlike it in having no exopod. 



The characters of the first and second pleopods are shown in 

 the figures. The other three pairs have two very unequal branches. 

 The uropods extend considerably beyond the telson, the inner branch 

 without the peduncle being subequal to it in length ; the outer 

 branch is broader and rather longer, with a simple unemarginate 

 outer edge, ending in a very small tooth, beyond which the curved 

 strongly setose apical border is scarcely produced. Total length of 

 specimen 65'5 mm., of which the carapace with rostrum occupied 

 25 mm., the sixth pleon segment 7 rum., and the telson 9'5 mm. 



The specimen was obtained by Mr. K. H. Barnard in Durban 

 Bay. In the same gathering were included small specimens which 

 I assign to Penaeus caeruleus, and one with seven irregularly spaced 

 dorsal and five ventral teeth on the carapace and elongate rostrum, 

 which I leave for the present undetermined. A 2231.
