1034. O. POLYACANTHA, sp. nov. (TroXiis, many + Sm^fc, spine). Plate 14, f. 6, 7. 



Disk 6.5 mm. in diameter; arms about 35 mm. long. Similar to 0. pan- 

 therina Koehler in many features but quite different in arm-spines and color. 

 The arms also are relatively shorter being only 5-6 times the disk-diameter 

 instead of 8-9 times. There are 10-11 arm-spines on each joint (hence the name) 

 even far out on the arm; the lowest is the longest and nearly or quite equals 

 two arm-joints; the next one is noticeably shorter; the middle ones are short- 

 est, scarcely equalling a joint; the upper ones exceed a~ joint and are the flattest 

 and broadest spines in the series; all the spines (except the uppermost one or 

 two) are slender and the middle ones are very slender and bluntly pointed. 

 Color (dried) : — disk very light with scattered spots and small blotches of pale
