Naturf. Versammil. 1869 (1870), p. xlv (teste Lyman). 
Arms eight times or more the radius of the disk. Disk quinque- 
lobate; covering-scales small, regularly imbricating, smaller below 
than above, not forming spines. Radial shields rather small, quite 
or almost touching externally, separated internally, where they are 
not so wide. The longish, delicate, flattened arms carry from four 
to six not stout spines; two tentacle-scales; lower arm-plates 
longitudinally sulcate, almost quadrate, sometimes with a shallow 
notch in their distal edge. Two mouth-papille, one at the side and 
one at the angle. A central plate with a rosette of five on the 
dorsal surface of the disk. 
This is a species which exhibits very great variation, not only in 
the proportional length of the arms, but the forms of the disk, the 
distinctness of the central rosette-plates, the extent of the calcifi- 
cation of the under arm-plates, and the colour. 
Colour, in spirit, whitish to brownish.
