A MONOGRAPH OF THE EXISTING CRINOIDS 49 



of the edge from which serrate ridges gradually extend themselves 1"*^™* 

 they completely span the brachial, so that the brachials in the outer half of the arm 

 have a median longitudinal band of fine spmes. 



Locality. -E*t of Fhnders Island, Bass Strait; 128-183 meters; Endeavour De- 

 cember 4, 1913 [H. L. Clark, 1916; A. H. Clark, 1918 (Tasmania)] (2, M. C. Z., 717, 



^ffii^-This species was described in 1916 by Dr. Hubert Lyman Clark from 

 two Secimens that had been dredged by the Australian ^^nes Invest.ga^on ship 

 Endeavour east of Fhnders Island in 70-100 fathoms on December 4 1913. Dr. Clark 

 2d that while this species resembles both O. komachi and C. helene m the general 

 character rf the arms the much more numerous cirrus segments, the longer pinnules 

 an" the markedly corneal centrodorsal seem to prove that it is quite chstinct. He 

 emartd that t/e genus was not known previously from Austrian water. 



In 1918 I listed this species as one of the crmoids known from Tasmaman seas.
