Description. — Centrodorsal conical. 3 mm. broad at the base and 3 mm. 

 high, the cirrus sockets arranged in six closely crowded alternating rows. The 

 centrodorsal as a whole resembles closely that of the species of Hathrometra. 



Cirri about LXX, all lacking. 



Radials extending slightly beyond the edge of the centrodorsal, diverging 

 at an acute angle in the angles of the calyx; IBr, somewhat trapezoidal, 

 about three times as broad as long, not in contact basally; IBr^ rhombic, 

 the free lateral edges rather longer than those of the IBr| , forming with 

 them somewhat more than a right angle ; synarthrial tubercles moderately 

 developed. 



Ten arms about 60 mm. long : first brachial longer outwardly than inwardly, 

 slightly incised by the second, not united interiorly, but the inner edges diverg- 

 ing at approximately a right angle ; second brachial nearly twice as large, 

 irregularly quadrate, with a rounded posterior projection incising the first; third 

 and fourth brachials (syzygial pair) about as long as broad; next eight or 

 nine brachials slightly wedge-shaped, half again as broad as long, then becoming 

 almost or quite triangular, about as long as broad, and further out on the arm
