Here described from a specimen 210 millimeters long, from 

 Masbate, Bureau of Science collection No. 1087, and two speci- 

 mens sent me by Mr. H. R. Montalban, who obtained them in 

 October, 1921, from a fish trap in the mouth of a river near Iba, 

 Zambales. One is a female 350 millimeters long, ready to spawn, 

 the other a male 320 millimeters long, likewise ready for the 

 reproductive act. 



Through the courtesy of the Department of Zoology of the 

 College of Agriculture at Los Banos I have obtained, as this 

 goes to press, two more specimens, 185 and 195 millimeters long. 

 They were found in holes in a stump in sea water at Palanas, 

 Lemery, Batangas Province, Luzon, January 5, 1923. 



This rare species was described by Bleeker from Bum Island, 

 in the Moluccas, and from Rotti Island, southeast of Timor. 

 Weber and Beaufort have specimens also from Simalur and Kara- 

 kelang Islands.
