Clark — Seventeen New East Indian Crinoids. 25 



broader than long, the fourth is about as long as broad, and the distal 

 twice as long a< broad. Ps is 2.5 mm. long with twelve segments and 

 resembles l'i, but is very slightly stouter basal ly and possesses longer 

 segments distally; the following pinnules resemble I'.-,. The distal pin- 

 nules are 4 mm. long with fifteen segments of which the distal are nearly 

 or quite three times as long as broad. 



The color is white or brownish white with numerous regular purple 

 spots on the division series and arm bases, and in band-like areas on the 

 outer part of the anus; the cirri are white, with each segment banded 

 with purple.

Eudiocrinus junceus sp. nov. 



The centrodorsal is discoidal, moderately thick, the .sides sloping inward 

 rather strongly; the fiat dorsal pole is 1 mm. to 1.5 mm. in diameter; the 

 cirrus sockets are arranged in two closely crowded and irregular rows. 



The cirri are xxv, 2'2, 23 mm. long, greatly elongated with elongated 

 segments, very slender, tapering from the base to the tip, rather more 

 in the first three or four segments than subsequently. The first segment 

 is short, the second not so long as broad, the third nearly or quite twice 

 as long as the proximal diameter, the fourth about four times as long as 

 the median diameter, the sixth, seventh and eighth very slightly longer; 



fr this point the length almost imperceptibly decreases so that the 



seventeenth and following are slightly over twice as long as broad; the 

 penultimate is half again as long as broad and tapers somewhat distally ; 

 the opposing spine is represented by a small, rounded subterminal 

 tubercle; the terminal claw is slightly longer than the penultimate seg- 

 ment, very slender and very sharp, only slightly curved. The second 

 and third segments are rather strongly constricted centrally, and the 

 sixth and following have moderately expanded and slightly overlapping 

 distal ends; both of these characters gradually the away distally. The 

 cirri are rather strongly compressed laterally from the fifth segment 

 onward. 



The radials are just visible beyond the edge of the centrodorsal ; their 

 distal horder is swollen and turned outward, smooth or evenly tubercu- 

 lated. The ossicles of the i Br series ( which are united in a pseudosyzy- 

 gial pair) taken together are oblong, not quite twice as broad as long; 

 both the proximal and the distal borders are turned outward, the former 

 slightly, hut the latter standing up at right angles to the general surface 

 of the segment, with a smooth ami somewhat thickened edge ; the proxi- 

 mal edge may be more or less scalloped, and hears just within the border 

 a prominent rounded tubercle; the produced distal edge is thickest and 

 most prominent in the mid-dorsal half, this portion being distally evenly 

 concave; the remainder of the distal edge may he broadly scalloped. 



The five arms are '.hi mm. long; the first brachial i< oblong, two and 

 one-half to three times as broad as long, the proximal and distal edges 

 slightly thickened and everted; the second brachial is similar, hut the
