2X2 The Philippine Journal of Science 1923 



This species was collected by Jagor on a coral reef near 

 Lauang, on the north coast of Samar, but has not been obtained 

 since then in the Philippines though it undoubtedly is widely 

 distributed in the Archipelago. It is abundant in the seas and 

 river mouths of India, being common in the Hooghly at Calcutta, 

 and is found in the Indian Ocean from He de Bourbon north- 

 eastward and in the East Indies to Borneo and Ceram. It at- 

 tains a length of over 600 millimeters.
