this species. 
Anthostoma fragile Verrill.

Clapar^de remarks that Ancistria Quatr. is founded on 
a Capitella. I know very little indeed about this group, 
but am certain that my specimens belong to Ancistria as 
defined by Quatrefages and have found it impossible to 
separate them from A. minima.
