124. A. PULCHRA, sp. nov. (pulcher, beautiful). Plate 2, f. 7. 



Disk, 8 mm. in diameter; arms about 50 mm. long. Similar to annulata 

 but differing in two striking particulars. On the arms, the annulations of 

 booklets appear to alternate with annula of smooth tubercles. Comparison 

 with annulata shows that the series of large, smooth plates, in the middle of 

 the paved valleys between the annulations of booklets in that species, has, 

 in pulchra become greatly enlarged and conspicuously elevated. At the same 

 time it has become light colored in marked contrast to the smooth plates on 

 either side. Consequently there are really annulations of smooth tubercles 

 alternating with the annulations of booklets. Distally these annulations of 

 tubercles become less and less evident and near the tip of the arm they are indi- 

 cated only by a light-colored hne. On the disk, there are no lines of tubercles 

 or booklets, across the radial shields, except at the distal ends. Instead, each
