" Les plaques marginales sont au nombre de 21 à chaque bras, les ven- 

 b-ales présentent de petites écailles isolées, saillantes, en forme de piquants, 

 dont la plus externe est x)lus longue que le piquant marginal, lequel est 

 d'ailleui-s pointu et un i>en aplati. Les plaques marginales dorsales, au 

 milieu des bras, sont aussi larges que liantes ; elles portent, en dehors, un 

 petit piquant conique. L'aire paxillaire des bras, entre les plaques marginales, 

 est très-large, eUe égale plus de trois fois la largeur de ces plaques, vers le 

 milieu des bras, La plaque madré]X)rique est très-près du bord.

In the description of Astropeden 

 armaius M, Tr. (from Japan) it is 

 stated that, the second, third and 

 fouiih upper marginal plates from 

 the arm angle are always without 

 spines. In the example lying before 

 me, this is tme only in so far as it 

 relates to two of the arm angles, 

 but not for the other three ; in one 

 of these only No. 2 and 3 are 

 destitute of S]3ines on the one side 

 and No. 2 on the other ; in the 

 second all the tln-ee are indeed mi- 

 armed on one side, but only No. 2 

 and 3 on the other ; and in the 

 third ai*m angle they aU bear spines, 

 but these are, for No. 2 on one side and 

 No. 3 and 4 on the other not a little 

 smaller than those between wliicli 

 tliej' are found ; moreover, the inner- 

 most plate of each series, which else- 

 where is apt to bear a very large 

 spine, has here only a very small 

 one, wliich however is not found at 

 its customary spot on one of the
