 the inner eyes of the triangular figures are the smallest of the 

 group, and are of an opaline tint with black rings.

 with rather long, fine black hairs, and few short stout spines.

 tinged with red, directed backw^ards, spiral at base, tapering, and 

 terminating with a long strong spine, the spine directed outwards 

 in a horizontal position.
