A MONOGRAPH OF THE EXISTING CRINOIDS 413 



"India." [A. H. Clark, 1909, 1911, 1912, 1918] (2, U.S.N.M., 35242; I. M.). 



No locality [A. H. Clark, 1912] (fragments, H. M.). 



Geographical range. From southern Luzon, Philippines, southward to the Pater- 

 noster Islands (north of Sumbava) and westward to "India" (possibly Ceylon). 



Bathymetrical range. From the shoreline down to 38 meters. 



History. This species was first described under the name of Himerometra echinus 

 from a specimen dredged by the Albatross at station 5147 in 1908. In the year follow- 

 ing another specimen from the Investigator collection labeled "India" was described 

 under the name of Stephanometra coronata. 



In 1911 a specimen of Stephanometra coronata was recorded that had been taken 

 by the Albatross at Port Busin on Barias Island, and it was noted that this specimen 

 closely resembled the type (with which it had been directly compared) in the Indian 

 Museum at Calcutta. 



In a paper on the crinoids of the Hamburg Museum published in 1912, some arm 

 fragments without locality were recorded, and coronata was placed in the synonymy 

 of Stephanometra echinus. 



In my memoir on the crinoids of the Indian Ocean published in 1912, I rede- 

 scribed the type specimen of Stephanometra coronata in detail and figured it and also 

 listed S. echinus from the Philippines in 21 fathoms. 



In the report on the ciinoids of the Siboga expedition published in 1918, 1 recorded 

 Stephanometra echinus from stations 40 and 99 and gave notes on the specimens. In 

 this report coronata was placed as a synonym under echinus. 



In 1936 Dr. Torsten Gislen recorded and gave notes on a specimen from Pulo 

 Condor, Cochinchina.
