posus as a distinct species, though a similar development of 

 the abactinal skeleton may be found in some specimens of the 

 latter. However, it is of little importance, if it be called a 

 distinct species or variety, if it be only kept distinct from 

 the typical S.papposus. — Possibly it is also nearly related to 

 S. echinatus Storm, in which species the abactinal skeleton is 

 likewise composed of «cruciform» plates. But the description 

 and figure of this species, given by Storm are not sufficient 

 for recognizing the species with certainty.

In the large specimen all the spines and paxillae are 

 clothed with a thick skin, in the same manner as in the large 

 specimen mentioned by Duncan & Sladen. The arms are 

 very broad almost to the end (not so in Duncan & Sladen's 

 specimen). There is an unusually broad naked space between 

 the ventral and dorsal marginal paxillae in the outer half of 

 the arm. 



With regard to this species I might here only point out, that 

 the spines in the transverse series outside the adambulacral spines' 

 are distinctly thorny, whereas the latter are smooth. This is 

 most distinct in young specimens, where the spines are covered 

 only by a thin, translucent skin ; — another character by which 

 this very curious species is distinguished from the other species 

 of Solaster.
