 meters; June 1-7, 1914 [Gislen, 1924, 1937, 1934]. 



Geographical range. — Known only from Sagami Bay, Japan. 



Bathymetrical range. — From 183 to 730 (?740) meters. 



Thermal range. — One record, 5.44° C. 



History. — This species was originally described in 1907 under the name Antedon 

 aster from a specimen that had been dredged at station 5088 in Sagami Bay, Japan, 

 by the Albatross in 1906. Later in the same year Antedon aster was referred to the 

 new genus Thalassometra. In 1908 another specimen of Thalassometra aster was 

 recorded from off Okinose, Sagami Bay, and at the same time a very fine example from 

 off Misaki was described under the name of Thalassometra komachi. Both of these 

 had been dredged by Alan Owston in his yacht the Golden Hind. They formed part 

 of the large collection of crinoids purchased from Mr. Owston by Frank Springer and 

 deposited in the United States National Museum. In 1909 Thalassometra komachi 

 was referred to the new genus Cosmiomefra. 



Further study had shown that Cosmiometra komachi was merely a fully grown 

 example of the species originally described as Antedon aster and in 1915 this form was 

 listed as Cosmiometra aster, under which name it has since appeared. 



In 1914 Dr. Th. Mortensen had dredged three specimens of this species in Sagami 

 Bay, two small ones at station 15 and a larger one at station 25. Dr. Torsten Gislen 

 figured an articulation of a distal pinnule of one of these in 1924, and recorded and 

 gave notes on all three in 1927.
