NO. 1561. NEW UNSTALKED CRINOIDS— CLARK. 135 



gradualh" increase distal ly, where they are 6 or T mm. long, with 12-15 

 joints. The pinnules from about the tenth to the twenty-fourth brach- 

 ials have the first 5 or 6 joints somewhat, though not greatly, expanded. 



Color in life, lavender, the arms crossed })y bands of dull yellow; 

 cirri yellow; lower pinnules yellow, banded at the junction of alter- 

 nate joints with purple. Other specimens are similar, but the rays 

 and centro-dorsal orange, the cirri purple. Another type of coloration 

 is: raj'^s and centro-dorsal orange, the arms clear yellow, sometimes 

 faintly blotched with light purple; cirri deep purple, banded with 

 white.

6. ANTEDON CALLISTA, new species. 



Centro-dorsal short-columnar, bearing about 30 cirri in two rows; 

 these are 23 mm. long, slender, with about 10 joints, most of which 

 are longer than wide, the lower ones very nuich so: the distal two- 

 thirds bear dorsal spines. 



First radials comparatively large from one-half to nearly the whole 

 height of the second radials in the median line, not produced interra- 

 dially, in apposition all around, the sutures almost obsolete; second 

 radials low and wide, about four times as broad as long, roughly 

 oblong, the edges in apposition laterally; axillaries triangular or low 

 pentagonal, about twice as wide as high; radials and axillaries bluntl}^ 

 carinate; distichals (when present) 2, like the two outer radials, but 

 the first distichal has a broad lateral flange on its outer side. Fifteen 

 arms 70 mm. long, the first two l)rachials oblong, then quadrate to the 

 eighth, then triangular, about as long as wide; the brachials in the 

 proximal half of the arm are somewhat tuberculai" syzygies in the 

 third l)rachial, the eighth to twelfth (usually the eighth), and distally 

 at intervals of 2 or 3 joints. 



First pinnule 5 mm. long, very slender and delicate, the first two 

 joints greatly expanded, the remainder short and squarish; second ]5in- 

 nule 6 or 7 mm. long, with 20 joints, the first expanded, the next two 

 short, the remainder elongated. The following pinnules decrease very 

 slightly in length as far as the basal third of the arm, then increase 

 very slightly distally. The expansion of the proximal pinnule joints 

 is not marked after the first three. 



Color in life, white, a broad band of deep purple in the basal third 

 of the arm, and two or three narrower bands distally.
