238 BULLETIN 82, UNITED STATES NATIONAL MUSEUM 



specimen is pure white with a small reddish dot resembling a sacculus in size and 

 color on each pinnule segment, excepting for those of the 2 or 3 proximal pinnules. 



In the larger specimen the pure white ends of the pinnule segments contrast with 

 the darker central portion. In the smaller the larger segments are pure white, but 

 each has a small sharply outlined reddish brown dot. 



In a magnificient specimen from the University of Iowa's Barbados-Antigua 

 expedition station 51 the centrodorsal is thin discoidal with the flat dorsal pole 

 5 mm. in diameter and showing a shallow central depression. The cirri are XXIV, 

 13, from 12 to 14 mm. long. The 20 slender arms are about 150 mm. long. All of 

 the IIBr series are 4 (3+4). 



A small specimen collected by the same expedition at Barbados has 15 arms 

 45 mm. long. 



In the list of varieties of Adinometra echinoptera with their localities Hartlaub 

 gave Adinometra echinoptera var. rubiginosa-discoidea from Blake station 231. He 

 does not mention this combination in the text, and it is not quite clear to which 

 specimen he refers. It seems to be, however, the ll-armed example now in the 

 Museum of Comparative Zoology which he figured on Plate 17, Figure 9.
