A MONOGRAPH OF THE EXISTING CRINOIDS 203 



Himerometra robustipinna A. H. Clark, 1908; and Himerometra pulcher A. H.Clark, 

 1912 (new name for the preceding). 



In my notes on the recent crinoids in the British Museum published in 1913, 

 under the heading Himerometra robustipinna (P. H. Carpenter) I said of the type of 

 Bell's Antedon inopinata that the centrodorsal resembles that of the other species in 

 the genus Himerometra. 



Dr. August Reichensperger in 1913 described two specimens from Ceylon, which 

 he referred to Himerometra kraepelini. He remarked that from the fragmentary 

 description of Himerometra robustipinna published by me in 1908 it is to be 

 concluded that the latter is unquestionably nothing else than kraepelini, of which form 

 the lower pinnules are exceedingly characteristic. The name pulcher, suggested by 

 me in 1912 to replace robustipinna of 1908, he said must also be placed in the syno- 

 nymy of kraepelini. 



In a key to the species of Himerometra published in the report on the unstalked 

 crinoids collected by the Siboga in 1918 robustipinna was said, in a footnote, to include 

 the H. kraepelini and H. crassipinna of Reichensperger. 



In 1926 Dr. Hubert Lyman Clark recorded two specimens from the Great Barrier 

 Reef, Queensland, thus considerably extending the known range of the species.
