Off Amoy, China (lat. 24 06' N., long. 118 25' E.); 36 meters; bottom tem- 

 perature 76 F.; Capt. H. Christiansen, S. S. Nordiske, August 10, 1912 (2). PI. 61, 

 fig. 171. 



Geographical range. From Sagami Bay, southern Japan, southward to Amoy, 

 China. 



Bathymetrical range. Apparently from shallow water down to about 150 meters. 



History. This species was first mentioned (as a nomen nudum) and its range 

 given in 1915. In the following year it was described in detail on the basis of the 

 specimens from southern Japan. In 1918 it was inserted in the key to the species of 

 the genus Comantheria-m the report on the unstalked crinoids of the Siboga expedition.

Diagnostic features. Terminal combs occur on most of the genital pinnules and 

 at intervals on those in the distal portion of the arms. There are 40 (36) arms. 

 The cirri are from 13 to 15 mm. long and are composed of 16-18 segments, of which 

 the outer have dorsally a proximal tubercle as well as a produced distal edge or a 

 distal tubercle, so that the dorsal profile is bidentate. 



Description. The centrodorsal is discoidal, broad, with the broad bare polar 

 area flat, 5 mm. in diameter. The cirrus sockets are arranged in a single crowded 

 and somewhat irregular marginal row. 



The cirri are XX-XXII, 16-18, moderately slender, from 13 to 15 mm. in length. 

 The first 2 segments are about twice as broad as long, the third is slightly longer than 

 broad, the fourth-seventh or -eighth are half again as long as broad, and those fol- 

 lowing gradually decrease in length, so that the terminal 7 or 8 are about one-third 

 again as broad as long. The ninth is a transition segment, in the proximal three- 

 fourths rounded in cross section and with a dull surface like the segments preceding, 

 but with a polished surface like that of the succeeding segments in the distal fourth. 

 Following the transition segment, the segments become rather strongly compressed
