generally thickest about the middle, evenly tapering to the sharp 
points; the heads are beautifully marked off; they vary in length 
from ca. 200—700 fi by up to 21 in thickness.

One fine specimen and some fragments, resembling the type 
in general appearance; unfortunately the specimens are preserved 
in formaline, therefore somewhat macerated, so that the beautiful 
dermal reticulation, mentioned by Ridley and Dendy, could not 
be seen. As in the type, the oscula are also here situated on 
small, thinwalled elevations. The skeletal arrangement agrees fairly 
well with the type. The spicules are of the same shape, varying 
from ca. 200—1400 p, thus a little larger variation-range than in 
the type.
