PART 5 A MONOGRAPH OF THE EXISTING CKINOIDS 711 



Although Carpenter recognized the fact that the American form is larger than the 

 European, with more cirrus segments, he always united the two under the same specific 

 name, in which procedure he has been followed by all succeeding workers. 



In 1901 Howe recorded this species again — for the last time — from off Martha's 

 \'ineyard. 



Grieg in 1903 pubhshed a detailed comparison between this type and its European 

 representative, Hartlaub in 1912 discussed it in considerable detail, on the basis of 

 the specimens previously recorded by Agassiz (1880), from which the label had been 

 lost, and in 1914 and 1917 F. W. Clarke and Wheeler pubhshed analyses of its skeleton.
