the part distally of the main spine there are only one or two transverse rows of hairs. The roel- 

 shaped process has three short, powerful spines distally. Basale : The backward pointing process 

 has four distal bristles, four triaena bristles and two dwarf bristles. The anterior of the triaena 

 bristles was short and weak with very weak secondary teeth, the others were of the same type 

 as in other species in this group, i. e. with relatively few (from two to five pairs?) of secondary 

 sjjines under the distal pair of spines. The glands of the process issue on an almost completely

reduced verruca. Somewhat in front of the middle of the dorsal side of this joint there is a single 

 bristle, which is somewhat shorter than the dorsal side of this joint j apart from this there are 

 no hairs or bristles on the middle of the dorsal side of this joint. One of the two dorso-distal 

 bristles on this joint is unusually short, scarcely half as long as the anterior side of the first 

 endopodite joint. The e x o p o d i t e is comparatively large; if its end bristles are included, it 

 is about as long as the anterior side of the first endopodite joint. E n d o p o d i t e: The first 

 joint is not armed anteriorly with chitinous spines. The second joint has at least two proximal 

 bristles; their lengtli I was not .ible to observe. No long, narrow bristle, with short hairs,
