Excerpt from Asteroidea of the North Pacific and Adjacent Waters, Vol. 3: Forcipulata Description. - This species is very variable. While large specimens all have the same general appearance and are easily recognized, a detailed analysis of the strue ture will reveal considerable diversity in the size of the skeletal parts, especially of the dorsum, and in the number, robustness, and form of the spines. The breadth of the ray increases with age in such a way as to alter very materially the appearance of the animals. Quite immature specimens are therefore unlike the adults in general appearance. The following description is based upon a large specimen from station 3242, 11 fathoms, Bristol Bay. (pl. 2, fig. 3; pl. 3, fig. Some of the variations exhibited by adults from southern Bering Sea are also noted. Under variations are listed the principal varieties which are present in a large series of specimens examined.
