234 DISCOVERY REPORTS 



To this synonymy Leipoldt, 1895, p. 563, adds: Asteracanthioii varhim Philippi, A. 

 fulgens Philippi, as well as several species, such as Anasterios mimita, Asterias perrieri 

 Smith, Asterias nipicola Verrill, and Calvasterias stolidota Sladen, which I consider to 

 be distinct.

 2 specimens. 



The largest specimen measures R 90 mm., r 20 mm., br 22 mm. (dry); the smallest 

 measures R 6-5 mm., r 2-5 mm. Typical specimens have a great abundance of crossed 

 pedicellariae all over the abactinal surface (on the plates and around the borders of the 

 papular areas), around the superomarginal spines, and on the upper side of outermost 

 inferomarginal spine. In the interradial channels there is a variable number of con- 

 spicuous straight pedicellariae considerably longer than broad, either tapered or blunt 

 ended while a variable number of similar ones are found in the actinal and intermarginal 

 channels. In little specimens they are entirely lacking. Along the ventrolateral border of 

 ray is a series of oblique combs of 3 or 4 spines the innermost of which is an actinal, the 

 others inferomarginal. There is a series of actinal papulae. Very small specimens lack 

 actinal plates, spines, and papulae, or have only a short series. 



In this species the abactinal skeleton is normally stout, but specimens are occasionally 

 met with in which the skeleton is weak and the crossed pedicellariae few in number 

 (Teal Inlet, Falkland Islands, Fisher, 193 1, p. 8, pi. 8). In young examples the abactinal 

 skeleton is nearly always weak and only a little better developed than in small examples 

 of mimita. The latter differs in having a thicker pustulate skin, few abactinal spinelets 

 and few pedicellariae.
