Locality : A single damaged specimen from 4 fathoms on mud. 

 Singapore. 



Distribution. Recorded from the Red Sea and Cape of Good 

 Hope to the Philippines ; it extends also into North and West 

 Australia, and according to Agassiz it is found in the Gulf of 

 California. 



There is some doubt as to whether this species is correctly 

 determined, on account of the broken condition of the posterior 

 end of the test; but the arrangement of the long serrated abactinal 

 spines and the shape of the actinostome resemble those parts in 

 L. elongata more than in L. suhcarinata, the only species with 

 which it could be confounded : the colour also is characteristic of 

 L. elongata, the large spines being yellow banded with violet as in 

 the type.

 t, xxviii. p. 44, 1883. 



Locality. Pulo Brani, Singapore. 



Habitat. This species appears to burrow in fine sand between 

 tide-marks in the same way as Echinocardium cordatum on our own 

 coasts. 



Distribution. Extends from the Red Sea to Sandwich Is. in the 

 Indo-Pacific circumtropical littoral region ; it is also recorded from 

 Australia and New Zealand. 



It is at once distinguished from Brissus carinatus by its cordi- 

 form subanal fasciole, narrower actinal plastron, and deep anterior 

 groove.
