Among the large series there are however some short, stout-rayed examples, not 

 differing from the above in spine characters. These have broader pedicellariae than 

 both shumaginensis and the small-spined intergradcs with multispina which are found 

 at Karltik, Kodiak Island. 



The abactinal spinelets are short, broadening toward the striate usually sub- 

 truncate tip, which is visually subcapitate and provided with numerous minute 

 points. The superomarginal spines, two or three in a vertical series to each plate, 

 are only a little larger than the adjacent dorsolaterals, but the inferomarginals, two 

 to a plate are decidedly longer and heavier, and are generally cylindrical or clavate, 

 subtruncate. There is a single short series of similar actinal spines, these with the 

 inferomarginals forming transverse series of three at base of ray. They are from 1.3 

 to 2 mm. long, while the superomarginals are 0.6 to 0.8 mm., and the abactinal about 

 0.5 mm. long. The adambulacral spines alternate one and two. 



The lateral, dorsolateral, and actinal "dermal" straight pedicellariae are of the 

 characteristic broad jawed, bivalve, goniasterid sort (pi. 48, fig. 5a) generally thicker 

 than the adjacent spines. The largest are in the supramarginal and intermarginal 

 channels; but smaller ones occur among the inferomarginal spines. Some of these 

 may have narrower jaws. 



Color in life. — Dr. G. Dallas Hanna, who collected a large series at Village Cliffs, 

 Village Point, and Zapadni Reef Rookery, St. Paul Island, made careful color notes 

 and recorded 25 variations, some of them minor. The following are the principal 

 color phases : 



1. Upper surface very dark green, borders of papular areas dark brown; actinal 

 surface and tube feet light transparent green, the margins flesh color (15 specimens). 



a. Margins pink instead of flesh color (one specimen). 



b. Margin of ventral surface lighter pink, and tube feet flesh color. (two speci- 

 mens). 



c. With small bright purple spots uniformly distributed on upper surface; flesh 

 color below, margins translucent green (one specimen). 



2. Similar to 1 but upper and lower surfaces slightly lighter (10 specimens). 

 a. Gray muddy green above, flesh color below (2 specimens; see 12). 



3. Upper surface very dark brown, papular areas black; tube feet light dirty 

 green; furrow bordered by flesh color (14 specimens). 



a. Lighter brown above, papular areas almost black (12 specimens). 

 I. Upper surface still lighter brown, papular areas black, tube feet dark green, 

 lighter green, or flesh color (four specimens). 

 c. Dark brown all over (one specimen). 



4. Upper surface dark buff; papular areas small, jet black; tube feet dirty green 

 bordered by flesh color (one specimen). 



'/. Lighter bull' above; actinal surface all flesh color (two specimens). 



5. Upper surface purple, sides brown; actinal surface flesh color (one specimen). 



6. Upper surface brick red all over; tube feet light dirty green bordered by pink- 

 ish flesh color (two specimens). 



7. I'pper surface light red with a few irregular blotches of blood red (one 

 specimen).
