Notes. — One of the specimens from station 12, Haiti (E. 5437) 

 (pi. 54, figs. 1, 2), is in the phiocry jytus stage. The disk is 2.7 mm 

 in diameter and the arms are 5 mm long. The entire upper and 

 under surface is uniformly covered with granules from which the 

 month papillae and tlie short conical arm spines project. On some 

 of the arms more or fewer of the upper arm plates show raised areas of 

 various sizes bare of granules indicating the beginning of the transi- 

 tion to the adult form. The lateral areas between the arm bases are 

 occupied by a single lai-ge somewhat swollen plate evenly covered, 

 like the rest of both surfaces, with closely set granules. The color is 

 uniform light and somewhat grayish green, lighter on the oral side.
