 lacrals numerous, crowded, with 3 to 4 margin- 

 al spines in row ; outside of these are 9 to 12 

 thicker, obtuse spines in four irregular rows; 

 all adambulacral spines resemble the actinal 

 granules, which are large, angular. No pedi-

SPINULOSIDA 



None of the species of the Order Spinulosida are 

 common in North Carolina. Although the two 

 "northern" sjjecies are very abundant north of the 

 State, they are rarely taken in North Carolina wa- 

 ters. The "southern" species have been taken only 

 in Onslow Bay.

Disc rather large, arms six to eight. Dorsal 

 surface covered with numerous paxillae which 

 are crowned with many long fine spinules. 

 Papulae in rather regular rows from center 

 out along arms. Inferomarginals conspicuous, 

 forming distinct fringe around border; su- 

 peromarginals not distinct from dorsals. 

 Adambulacrals with inner furrow comb of 

 three to four webbed spines and outer trans- 

 verse comb of about four larger spines. Oral 

 spines eight, with middle two largest and 

 longest. Anus central, protected by spines 

 of adjacent paxillae. Madreporite incon- 

 spicuous. Species known only from small, 

 probably juvenile specimens. Rr=2.6 : 1. Color
