Potentially than are ->\ Longiseriee on the abactina] area In soma variations Una 

 spineleta are bo arranged that a reticulate <>r areolated pattern is formed. Such 

 specimens may be readily distinguished from forms of A alatkenria by the presence 

 of a long Beriee of actinal Bpinee and by the situiII lanceolate straight pedicellariae of 



the sides of ray. 



The number of Buperomarginal Bpinee is usually three or four in an annate wr- 

 ii. mI Beriee, Owing to their smaller size they appear t<> be more spaced than in 

 Hitida The inferomarginal and actinal Bpinee are much slenderer than in atrtda 

 but number tlu> same. 



The lanceolate Btraighl pe.licellariac are appreciably -mailer than those of 



nitida, measuring 0.3 to 0.46 mm. (PI. 4'.'. fig. 2a The abactinal crossed pedi- 

 cellariae measure old to n 21 mm. 



This form predominates at St Paul, Pribilof Islands, where it far outnumbers 



nitida judging by the -cries collected by Dr. (i. I). Ilanna. The type trae taken at 



Village Point, July 25, 1920, among bowlders, between tides, along with /. aJaskmsis.
