South Ajrican Crustacea. 99 



outer margin of the base there is a row of 7 or 8 spirmlate 

 setae. In the second maxillae the proximal lobe is far less 

 prominent than the following deeply bifid lobe except in 

 respect of the very long setae with which it is fringed ; the top 

 of the vibratory plate is flattened. In the first maxillipeds the 

 apical joint is much shorter than the preceding, and is over- 

 topped by the long and broad exopodal plate. In the second 

 maxillipeds the second and third joints are coalesced though 

 their limits are defined, the exopod reaches much beyond the 

 down-bent sixth joint to which the triangular finger is 

 obliquely attached. In the third maxillipeds the antepenulti- 

 mate joint is notable for the strong flexure of the proximal 

 half and the great widening of the distal. 



The total length of the specimen was about 84 mm., the 

 carapace measuring 30 mm., of which the rostrum occupied 

 14 mm. The first and second segments of the pleon were 

 together 12'5 mm. long, equal to the third segment, including 

 its extended postero-dorsal tooth; the three following segments 

 together measured 23 mm., and the telson 12 mm. In adding 

 the lengths of the different parts, allowance must be made for 

 the overlapping, the process of the third pleon segment 

 extending over nearly half of the short fourth segment. Each 

 of the three following segments has a dorsal tooth, the last the 

 longest, but none of them very important. Plates illustrating 

 this and the next species are reserved for future publication.
