Obtained in abundance in Madras Harbour where it was 

 collected by Dr. Annandale at four stations. As Reichert remarks, 

 this species seems to be distributed throughout the warm seas. 

 The writer can bear witness to its presence in the warm waters 

 of the north Pacific ocean, from which region it has not hitherto 

 been reported. Specimens have been sent me from Hokkaido, 

 Japan, and from Honolulu, Hawaiian Islands. In the summer of 

 1905 it occurred in abundance in San Diego Bay, California. 

 There, in water 10 or 12 feet deep, it grew in luxuriant masses of 

 a green tint, the whole resembling clumps of freshly cut hay.
