Locality. This is perhaps the commonest Starfish in the district ; 



it lives in 3 to 10 fathoms on mud or shelly gravel, Singapore. 



I found a specimen infested by two individuals of a species of 



Thyca, they were fixed close together on the abactinal side. 



Distribution. Singapore to Australia, extends northwards to the 

 Korean Straits. 



Black pigment is developed on a variable number of the ventro- 

 lateral plates ; this completely disappears in alcohol specimens, but 

 is preserved with formol ; there seem to be only a few cases in 

 which the underside of starfish is pigmentfcd ; as in the case of the 

 black pigment often found lining the body-cavity of Holothurians, 

 its use is not in the least known.
