In the preceding list I have followed the classification proposed 

 by Matsumoto in 1915 ('15 [1], pp. 43-92) in a memoir which, though 

 short, is most noteworthy and abounding in far-reaching observa- 

 tions. The same classification was adopted by Dr. Hubert Lyman 

 Clark in his beautiful memoir entitled " Catalogue of Recent Ophiu- 

 rans," which also bears the date 1915. This work being destined to 

 be the reference work — and an exceedingly convenient one — for all 

 those who are engaged in studying the ophiurans I shall follow the 

 classification therein used. However, as my views diner in various 

 matters of detail from those of the learned American zoologist, a few 

 words of explanation are necessary, and at the same time it appears 

 to me advisable also to make a few remarks in regard to the classifi- 

 cation proposed by Matsumoto, in which H. L. Clark has thought it 

 necessary to introduce some slight modifications.
