mm 



the arms. Owing to the relatively great length of the brachials the pinnules are 

 rather widely separated, giving the arms a very characteristic appearance quite differ- 

 ent from that of any other of the small comatulids. 



Syzygies occur between brachials 3+4, 9 + 10, 14 + 15, and distally at intervals 

 of 2 muscular articidations. 



Pi and P, are absent. P2 (the lowest pinnule) is from 5 to 7 mm. long, slender 

 and evenlj^ tapering, but moderately stiff; it is composed of 10 segments, of which 

 the first two are about as long as broad and the remainder greatly elongated with 

 prominent and somewhat overlapping ends, becoming slightly shorter again distally; 

 the third to fifth segments may bear a more or less elongated gonad. P3 to Pj are 

 similar but shorter. The following pinnules become longer again and more slender; 

 they have the first segment short, the second about as long as broad, the third between 

 2 and 3 times as long as broad, and the following similar, but becoming progressively 

 elongated and very long and slender distally. 



Color. — The color in alcohol is white, with usually narrow well-spaced transverse 

 bands of browm on the arms.
