Solaster paxillatus. 

 Sladen, 1889. 'Challenger' Asteroidea, p. 452. 



Each of the three specimens has eight arms. In the smallest, R = 

 37 mm. In one of the large ones R = 135 and the ray is 35 mm. broad at 

 the disk-margin, while in the other large specimen, with the rays about 

 equally long, br is only 23 mm. These two large specimens have no locality 

 label but there is reason to think they came from Station 5694, southwest 

 of Santa Cruz Island, California, 640 fms. The small specimen is from 

 Station 5695, southwest of Santa Rosa Island, California, 534 fms.; bottom 

 Temp., 38.9. The occurrence of this Japanese species, so far south on the 

 American coast, is noteworthy, but I can find no good reason for refusing 

 to refer these specimens to that species.

 eleven. The largest specimen has R = 135 mm. while the smallest has R 

 only 20 mm.

There is a fine series of this interesting starfish, of which one has nine 

 rays, 26 have ten rays and one has eleven. The largest specimen has R = 

 160 mm. while in the smallest R is only about 13 mm.
