Previously recorded from Tongatabu, 18 fathoms, and off 

 Booby Island, Torres Strait, 6 to 8 fathoms. Also from 

 Java (G. S. Brady). 



The writer has recorded it from the littoral sands of the 

 seaward face of Cocos Island (coll. by Dr. C. W. Andrews).

This species has a wide distribution. The "Challenger" 

 dredgings yielding this species <vere from Port Jackson, 2 to 

 10 fathoms ; Booby Island. 6 to 8 fathoms ; and from anchor- 

 mud at 7 fathoms in Hong Kong Harbour. 



A right valve of this species was found in our dredging ; it 

 is not so sharply sculptured as in typical specimens, and at 

 first sight would suggest affinity with G. canal icidata, Reuss. 

 Our specimen differs from the last-named, however, in having 

 the anterior extremity of the carapace, in edge view, decidedly 

 wedge-shaped.
