cle, and there is a similar but less marked one on the 

 junction of the first and second brachials. Arms ten , of 

 150 -)- joints. First brachials rhomboidal , almost completely 

 united laterally; the second longer and more wedge- 

 shaped. These two joints and the axillaries have irregular 

 blunt processes on their outer edges. The next four or 

 five joints are transversely oblong. The following ones 

 longer, sharply wedgeshaped, and overlapping. Towards 

 the ends of the arms they become blunter and squarer. 

 The raised distal edges of all the joints are fringed with 

 short spines. 



The first syzygium is on the third brachial, and the 

 next is usually on the seventh or eighth brachial. After 

 this the syzygial interval may be from three to eighteen 

 joints, being usually three or four joints in the lower 

 parts of the arms, and six or seven joints in their outer 

 portions. The lower pinnules are stiff and styliform, con- 

 sisting of about fifteen long, cylindrical, and overlapping 

 joints with expanded and spiny distal edges. That on the 

 fourth brachial is slightly longer than that on the second; 

 and the following ones gradually diminish in stoutness 

 and stiffness, but increase in length and in the number 

 of joints. Those on the outer parts of the arms reach 

 nearly twenty millim. in length and consist of about thirty 

 elongated joints with expanded distal ends bearing nu- 

 merous spines, the outermost of which are much longer 

 than the rest. 



Disc naked and much incised ; 7 mm. in diameter. 



Spread, about 30 centim. 



Colour, dark reddish brown: sacculi moderately close 

 along the pinnule ambulacra.
