A MONOGRAPH OF THE EXISTING CRINOIDS 215 



to C. anceps might represent a new species, in which event it could be called C. aruensis. 

 Recognizing the rather obvious fact that Craspedometra, including acuticirra, ater, 

 madagascarensis, and amboinae, was quite impossible of definition as distinct from 

 Heterometra, in 1918 I included it in a key to the genera of the Himerometridae with 

 structural characters and a geographical range applying only to acuticirra, although 

 it was not specifically stated that this was the only species now included.
