The colors of living crinoids have not only as a rule been recorded under 

 conditions preventing an accurate color analysis, but also by observers not trained 

 in color work, so that the names of the colors as given are in many cases to be 

 regarded as somewhat indefinite. This is especially true in the case of the differen- 

 tiation between red and purple, purple and violet, and violet and black. 



As over 100 hues are mentioned, it seems advisable to simplify matters by 

 reducing the list to reasonable limits through a combination of the colors as 

 recorded under 10 readily differentiated heads, as follows : 



Yellow, including yellowish white, cream, clear yellow, lemon yellow, yellow, 

 yellowish, brilliant yellow, light yellow, sulphur yellow, dull yellow, gold, golden 

 yellow, canary yellow, ocher yellow, light chrome yellow, chrome yellow, greenish 

 yellow, and brownish yellow.

 yellowish red, orange red, and rusty red.

 rich purple, purplish gray, grayish purple, dull purple, deep purple, dark purple, 

 and maroon.

 brown, and purplish black.
