A MONOGRAPH OF THE EXISTING CRINOIDS 



29 



In 1915 the new genus Daidalometra was created for its reception and in 1916 the 

 range was again given. In my memoir on the unstalked crinoids of the Ok*. ex- 

 pedition published in 1918 it was included in a key to the species of the genus DauMo^ 

 metra, and was listed with its range and synonymy. In 1922 Prof. Torsten Gislen 

 compared it with his new species Stenometra dentata.
