208 ECHINODERMA OP THE INDIAN MuSgUM, PART VII. 



Locality. — About 30 miles west of Middle Andaman : about 485 fathoms. — One 

 mutilated specimen, agreeing well with Carpenter's description and figures. The 

 centrodorsal is rounded conical, i mm. broad at the base and 3 mm. high : tlie 

 cirrus sockets are arranged in ten columns, two to each radial area, those of each 

 radial area being separated interiorly by a rather strong ridge, exteriorly in close 

 apposition with the columns of adjacent radial areas: the dorsal pole is rough, 

 covered with irregular tubercles ; the disk is almost entirely covered with small 

 rounded concretions: the disk ambulacra are bordered with similar, but some- 

 what smaller and more thickly set, plates which become radially elongated about 

 the mouth ; the perisome of the arms is covered with small round concretions, 

 and the interbrachial perisome with large flat plates.
