It is stated, but probably in error, that the 1st peraeopod is shorter than the 

 2nii, and that only the Snd and 3d peraeopods in the 9 have exopods. The statements 

 would be more likely to apply to the 3d maxillipeds and the 1st and 2nd peraeapods. 

 L. about 1 mm.

Pseudorostral lobes in Q directed obliquely upwards, upper margin 

 straight, apically acute, in d horizontal, vertically truncate; antero-lateral 

 corners in 9 forming a triangular tooth with faint serration of lower margin 

 behind it, in c? rounded off. Median carina of carapace in 9 with a few 

 variable teeth and a large tooth near the hind margin overhanging a pre- 

 ceding depression, in the d a similar arrangement feebler or obsolete. In 

 the Q 3 subparallel ridges curve obliquely across the sides of the carapace, 

 the first on the frontal and pseudorostral lobes, the second passing from the 

 median depression towards the antero-lateral corner, the third from the hind 

 margin to the lower margin a little way behind the antero-lateral corners. 

 The first of these is wanting in the d. Antenna 1, S-^ joint not shorter
