I have found this species at but two stations in the Philippine 

 region— D5158 and D5164, Suiu Archipelago, ofT Tav.i Tawi, in 12 

 and 18 fathoms (22 and 33 meters;. The species is rare at both 

 stations. 



Brady records this from about the various East Indian Islands, 

 but I have failed to find it in the North PacifxC except at one station. 

 It did not occur in the material I had from about tlie HaY.aiian 

 Islands, and it seems to be very rare in the Indo-Pacific, being 

 replaced by various species of rbltoVotes . Dakin records it as rare 

 from the Gulf of Mannan, Ceylon. Ileron-AHcn and Earland do not 

 record it from the Kerimba Archipelago.
