A MONOGRAPH OF THE EXISTING CRINOIDS 431 



pole nearly flat bearing in the center a rosette of five conspicuous radially situated 

 tubercles. The columns of cirrus sockets are separated interradially by a narrow 

 sinuous groove and in the midradial line by a broad bare area. The cirri are XVII, 

 116-120. Two specimens have 20 arms. Two specimens have 12 arms; both of these 

 are small. In one the arms are about 60 mm. long. There are two IIBr series on one 

 postradial series. A very small specimen has 10 arms 30 mm. long. 



The specimen from the Danish Expedition to the Kei Islands station 26 consists 

 of the centrodorsal, cirri, and basal portion of the division series. The cirri are XXV, 

 110-112, 90-120 mm. long. 



The specimen from the Danish Expedition to the Kei Islands station 53 is very 

 small with 10 arms 30 mm. long. 



The specimen from the Danish Expedition to the Kei Islands station 54 has 12 

 arms measuring 115 mm. from the rim of the centrodorsal. The cirri are XII, 118- 

 1 T9, 112 mm. long. The radials have a median tubercle of which the maximum height 

 is in the proximal half. The IBr! have a very faint and indistinct median elevation. 

 The IBr 2 (axillaries) have a similar indistinct median elevation the highest points in 

 which are near the proximal border and halfway between the distal angle and the 

 proximal border. The elements of the IIBr series (which are 2) and the first two 

 brachials have the dorsal surface unmodified. PI is 7.5 mm. long with 14 segments, 

 scarcely tapering in the basal half but from that point on tapering gradually to the tip. 

 The genital pinnules are 15 mm. long with 18 segments. Pinnules 20 mm. from the 

 arm tip are 10 mm. long with 18-19 segments. In spite of the small number of arms 

 this appears to be a specimen of this species. 



The specimen from Siboga station 144 agrees well with the type from Albatross 

 station 5252. There are 20 arms 90-95 mm. long. The cirri are XX, 92-96, 78 mm. 

 long. The color in alcohol is white. 



The specimen from south of the eastern end of Java is a fine typical example of 

 the species. There are 18 arms 80-90 mm. long. The cirri are composed of 88-92 

 segments and are 60-75 mm. long. On one of the cirri the terminal claw has at the 

 base on the dorsal side a process exactly resembling an opposing spine that rises to a 

 height equal to about half the width of the base of the terminal claw.
