SEA LILIES, STARFISHES, ETC.—CLARK. 22 
the basal segments are smooth, while the aboral margins are 
more or less produced as flattened, spinulose projections ; 
the distal margins of all the segments, except the first five or 
six are finely spinulose, but none of these characteristics are 
at all conspicuous. Ps is much like Pe, but a little smaller, 
while Py, which is probably the shortest pinnule on the arm, 
is only a trifle shorter than P3;; succeeding pinnules become 
very slender, 8-9 mm. long and with 22 or more segments. 
On the basal half of the arm, the pinnule-segments, except 
the basal two or three, have distinctly, but finely spinulose 
aboral edges and distal margins, but on the outer half of the 
arm they seem to be quite smooth. 
Colour (dry) of centrodorsal, basal portion of the cirri, all 
arm-segments and pinnules, uniformly pale buff or brownish- 
white ; cirri gradually become dull purple at tip, the lighter 
shade being confined more and more completely to the ventral 
side of the segments and finally is crowded out altogether ; 
arm joints rich reddish-purple, in sharp and handsome con- 
trast to the light segments; oral surface of pinnules very 
dark, almost black. One specimen. 
This seems to be a well-marked species, the long cirri, the 
flexible first pimnule, and the absence of conspicuous pro- 
cesses on the basal pinnule-segments combining to distinguish 
it at once from the other species of the genus.
