80 BULLETIN 2 01, UNITED STATES NATIONAL MUSEUM 



Distribution. — The species has been recorded from the waters of the 

 East Indian Archipelago (Hansen), Andaman Islands (Tattersall), 

 and the Great Barrier Reef, Australia (Tattersall), range now in- 

 cluding the Philippine Islands. It is one of the rarer species of the 

 genus and I was able to detect only one specimen in the large amount 

 of material of this genus in the National Museum collection. 



Remarks. — This specimen agrees with those that I recorded from 

 India in having three small equal spines at the center of the apex of 

 the telson between the median pair of long spines. Otherwise the 

 specimen, which is not in good condition, agrees with Hansen's de- 

 scription and figures.

 coast of India (Tattersall), and the Barrier Reef, Australia (Tatter- 

 sall) ; Philippine Islands included by present record. It is appar- 

 ently widely distributed in the tropical waters of the west Pacific and 

 Indian Oceans.
