straight row ; next, and close to these, there is a row of three or four 

 larger, angular blunt spinulesof the same height; these are followed 

 by another row of three or four similar but small spines, in a slightly 

 curved row; then there is a group oT five or six, sometimes forming 

 rows, on the outer part ©f this plate, of the same form and size as 

 the actinal granules. 



The actinal plates are numerous and even, closely crowded, mostly 

 rhombic or squarish, covered with granules that become angular 

 where most crowded. 



Large valvular pedicellariae occupy the center of many of the 

 plates in the series next the adambulacral ; they are about as broad 

 as half the diameter of the plate, or more. 



The dentary plates are not prominent, but are covered with 

 numerous prismatic granules and spinules, larger than those of the 

 adambulacral plates. 



The madreporic plate is large, round, with numerous fine g3'ri. 

 The dorsal nephridial pore is surrounded with granules larger then 

 those of the surrounding plates.

Plate XXVIll. Figures 3, 3a. 



Form pentagonal, with the sides only slightly incurved ; rays very 

 short, triangular, and obtuse, with the tip turned up and terminated 

 by a small, conical plate. 



Marginal plates large, median ones nearly square, higher than long, 

 the upper and lower nearly corresponding, fourteen in the dorsal 

 series and sixteen in the ventral series, all uniformly covered with 

 father coarse, rounded granules, standing a little apart; the margins 

 of the plates with a regular row of granules of about the same size. 

 The three distal dorsal plates are in contact medially. Apical plate 

 small, obovate. 



Abactinal plates nearly flat, the primary ones rather large, rounded 

 or hexagonal with rounded angles, with many small, rounded, unequal 

 secondary ones interspersed ; all are uniformly covered with ratheF 

 coarse, spaced granules, like those of the marginal plates, so that the 

 whole of the upper surface has a remarkably uniform granular coat-
