Dorocidaris papillata A. Agassiz. 
Our specimens are near the variety abyssicola. The long 
Spines appear nearly smooth to the naked eye, but are finely 
fluted and minutely spinulose; they increase gradually in size 
for a short distance and then taper very gradually to the trun-

and truncate, with the distal half strongly sulcated ; those near 
the mouth flat and curved. Color of test and small spines, pale 
pink; large spines, at base, mostly pale pink above, with three 
or four broad, faint bands of dull greenish brown; scattered
