p. 75. 



Description. — Centrodorsal a thin disk, the bare flat dorsal pole I mm. in 

 diameter ; cirrus sockets arranged in a single marginal row. 



Cirri XII, 12, 5 mm. long ; first two segments twice as broad as long third 

 half again as broad as long, fourth twice as long as broad : following segments 

 very gradually decreasing in length, the antepenultimate being about one third 

 again as long as broad : third and fourth segments strongly " dice-box " shaped, 

 fifth and sixth slightly so, the following with practically straight edges; cirri 

 proximally almost circular in cross-section, after the fifth segment becoming 

 laterally compre-sed and therefore broader in lateral view ; no dorsal spines or 

 projections ; opposing spine median, small, scarcely equalling one fourth the 

 diameter of the penultimate segment in height. 



Arms and pinnules as in Eudiocrinus indivisus, the overlapping of the bra- 

 hials and pinnulars being moderately marked ;. the arms are 15 mm. long.
