rather needed. 
The largest specimens measure 6 mm diameter of disk, with 
i an armlength of ca. 25 mm. Although fairly robust looking, it is 
exceedingly brittle, which may be due to the narrowness of the

The disk generally swollen and bulging out between the arms. The 
tubefeet are somewhat papillose. In larger specimens there may be
