Arms eight times or more the radius of the disk. Disk quiuque- 

 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-papillae, 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.
