168 RECENT OPHIURANS. 



more restricted at present. Today we find there are 1,412 species to be listed, 

 grouped in 189 genera. Of these, 753 species are represented in the M. C. Z. 

 collection, which includes more than 21,000 specimens, while 659 species are 

 wanting. Of the genera, we have 140, while forty-nine are desiderata. The 

 Museum collection contains the holotypes of 171 species and paratypes or 

 cotypes of 325 others. We thus have type material of more than one third of 

 all Recent ophiurans. Mr. Lyman was himself the describer of 297 of the 

 species here listed. Since his death, Dr. Koehler of the University of Lyons 

 has become our great authority on the group and in his numerous and valuable 

 reports, he has described for the first time 361 species. I cannot refrain from 

 adding that the quality of Dr. Koehler's publications is even more remarkable 

 than their volume, and I have had occasions every day during the preparation 

 of this catalogue to be grateful to him for his bibliographies and synonymies, 

 his accurate and complete descriptions, and his reliable figures.
