History. — Antedon hepburniana was originally described in 1907 from a specimen 

 dredged by the Albatross at station 4890. In my first revision of the genus Antedon 

 published later in the same year hepburniana was removed to the new genus Oharito- 

 metra, and in 1908 Charitometra hepburniana was listed as a Japanese species. In 

 another paper published toward the end of 1908 Charitometra hepburniana was given as 

 a representative of a nonoceanic group of comatulids. 



In my revision of the families Thalassometridae and Himerometridae published 

 in 1909 Antedon hepburniana was made the type of the new genus Strotometra, and 

 later in the same year a specimen of Strotometra hepburniana was recorded from south 

 of the Goto Islands and notes were given on it. In my memoir on the crinoids of the 

 Indian Ocean published in 1912 Strotometra hepburniana was listed and the synonymy 

 and range were given, and this information was repeated in 1913. In 1913 also, in a 

 paper on the crinoids of the British Museum, S. parvipinna was compared with S. 

 hepburniana . In 1915 S. hepburinana was listed as a southern Japanese species, and 

 t lie range and its significance were discussed. In my report on the unstalked crinoids 

 of the Siboga Expedition published in 1918 hepburniana was included in the key to the 

 species of Strotometra, the synonymy and range were given, and its relationship to 

 S. parvipinna was mentioned. In a popular article on sea lilies and feather stars 

 published in 1921 the side plates of Strotometra hepburniana were figured, the two 

 figures given (under one number) being copies of figures 810 and 811 on page 385 of 

 Part 2.
