MONOGKAI'H OF THE EXISTING CRINOIDS. 703 



The coloration of specimens of the following species has been recorded : 

 [After the completion of this section Dr. H. L. Clark turned over to me a 



great number of color notes, mostly based upon specimens collected at Port Galera, 



Mindoro, Philippine Islands, by Dr. L. E. Griffin, in April, May, and June, 1912. 



These are given between brackets in the following pages, but have not been used 



in preparing the general conclusions regarding color.]
