and usually dull white, spotted more or less thickly with grayish or 

 reddish purple, resembling some color phases of ^i. diomedege,. One 

 specimen of A. multicolor is white, with purple bands, almost exactly 

 like the type of A. callwta. A. ■ ersicolor, which is most nearly allied 

 to A. laulticoloT^ is reddish brown, resembling species of the A. palmata 

 group, but quite different from any known form of coloration in its 

 own group. A. propiiiqita, also, which is reddish brown marbled with 

 white, is quite different from any others in the group.

2. ANTEDON VERSICOLOR, new species. 



Centro-dorsal a low disk, bearing 20-25 marginal cirri; these are 

 moderatel}" stout, 23 mm. long, composed of 45 short, squarish joints, 

 overlapping somewhat, and bearing spines distally. 



First radials visible as triangles in the interradial areas, the distal 

 apices much produced; the sutures between the first radials are dis- 

 tinctly \'isible; second radials oblong, between three and four times as 

 wide as high, bluntly carinate, in apposition basally, free distally; 

 axillaries widely pentagonal, twice as wide as high, bluntly carinate 

 in their posterior half, wide!}' separated; distichals like the two outer 

 radials, but rather higher in proportion. Twenty arms 9(» mm. long 

 with 130 brachials, the first 5 irregularl}" oblong, then quadrate to the 

 twelfth, after which they become triangular, about as high as wide, 

 the long outer side convex and bearing the pinnule at its distal apex; 

 brachials strongly overlapping, slightly compressed and slightly cari- 

 nate; first syzj'gy in the third brachial, another about the eighteenth, 

 and others distally at intervals of one, two, or three joints. 



First pituiule about 7 nuu. long, slender, delicate, and flexible, with 

 30 joints, the first enormously" expanded, the second very broad and 

 trapezoidal, the others very small and square; second pinnule 10 nnu. 

 long, stiff' and spinelike, with 25 joints, the first two much enlarged, 

 the remainder elongated; third pinnule 13 nun. long, resembling the 

 second, but with the joints more elongate; fourth similar, but slightly 

 shorter; the following pinnules decrease in length to about the ninth, 

 which is 7 mm. long with 15 joints, the first two broad, the others 

 elongated, after which there is a slight increase in length distally; the 

 distal expansion of the first joint is marked on all the pinnules, but 

 less so distally; on most of the pinnules after the fifth it rises into a 

 low tubercle. 



Color in life rich, deep purplish brown, the basal portion of the 

 arms with a row of lateral 3"ellow spots; rays yellow, transversely 

 banded with purplish brown; cirri purplish brown, with the distal 

 half yellow; disk purplish brown, marbled with yellow in the inter- 

 ambulacral areas.
