pil: 
A species often confounded with A. chiajii, but distinguished 
from it by the softness of the ventral surface of the disk, owing to 
the reduction or absence of the scales, and by the absence of 
tentacle-scales. Further, there is never a prominent rosette of a 
central and five other scales, and some of the arm-spines sometimes 
have a minute cross-piece. ‘The arms are longer, and the radial 
plates are narrower and set more parallel to one another. 
Colour, when dry, brownish. 
Much more difficult to preserve satisfactorily than A. chiajit. 
Variation probably considerable. 
Distribution. Eastern side of North Atlantic; Mediterranean.
