SURFACE COPEPODA OF THE GULF OF MANNAR. 239 



Several examples of this species were obtained from the 

 pearl banks. Though differing in several unimportant details 

 from the original description, I have no doubt that the above 

 is the correct specific identity. In the present specimens, the 

 genital segment of the abdomen in the female frequently bears 

 a small spine on the dorsal surface and somewhat towards the 

 left side, in addition to the two on the right side described by 

 Thompson & Scott ; in all my specimens the furcal setae are 

 plumose.
