fourth article of maxillipcdal palp styliform, armed apically with a

Remarks. — The original description of this species by Giles was 

 rather sketchy and erroneously illustrated. In my 1957 paper I erected 

 a new species for specimens from southern California on the basis of 

 geography but Pillai's excellent paper (1957) on this species from India 

 shows that the Californian and Indian specimens are identical. For a 

 supposedly benthic amphipod belonging to a group which does not pro- 

 duce larvae this appears to be a peculiar distribution. Nevertheless the 

 two collections are identical. 



Material examined. — 77 specimens at 6 stations. 

 Distribution. — Madras coast; Ceylon; Southern California coastal 

 shelf, 7.5 to 10 fms.
