From all the Philippine collections examined this has been found 

 but a few times, and then in small numbers. It is abundant farther 

 south, especiall}^^ in the South Pacific islands and off Australia, from 

 where I have had abundant material. Millett records it as very 

 rare in the Malay Archipelago collections, finding it at but one 

 station. This accords with the results I have had from the Philip- 

 pines and with Carpenter, who speaks of it as — 



found in greatest size and abundance in the Australian and Polynesian Seas, occurring 

 chiefly in the shelly sands of rather shallow water; and * * * does not appear to 

 range far beyond those regions.

Specimens have not been at all abundant in the Philippine collec- 

 tions. There are records from five stations from the following localities: 

 Sulu Archipelago, off Tawi Tawi; off Jolo; off Romblon; and off 

 eastern Panay. These range in depth from 24 to 318 fathoms (44 to 

 582 meters), three of them in less than 35 fathoms (66 meters).
