" Ai-ms short aud broad, disk large ; marginals very large, extending 

 considerably on to both ventral and dorsal surfaces. Ambulacra rather 

 iiaiTow, bordered by a very large number of spines ; these are in five trans- 

 verse rows, aud the inner have again five in each long row ; in the outer 

 the spines are much larger and less numerous. The intermediate plates, 

 Avhich extend but a short way bayond the disk, are covered with large flat 

 granules and a few larger flattened spines, of much the same size as the 

 adambulacral spines. The inferoraargiuals and superomarginals at the 

 roimded angles of the disk very long, wider within than without ; fm-ther 

 out the plates are wider, and the outer and inner edges are of the same 

 l)readth. About twenty-five to thii-ty plates on either side of each arm ; 

 tliese plates are sometimes broken into two ; they are in each row covered 

 l)y a close pavement of polygonal plates, some of which, in the lower series, 

 become jîrolonged into distinct spines. The dorsal surface is occupied by a 

 regidar x^^^^vement of quadrate or polygonal x:)lates, each of which may be 

 resolved into a number of fine s^^ines flattened at their free ends. Among 

 them the madi'eporite, which is situated not far from the centre, may be 

 easily detected.
