Geographical range. Southern Japan, from Kiu-Shiu to Sagami Bay. 



Bathymetrical range. From 100 (?95) to 274 meters; the average of 10 records 

 is 169 meters. 



Thermal range. From 11.11 C. to 15.89 C.; the average of 3 records is 13.26 C. 



Remarks. This species was originally described in 1907 from specimens taken by 

 the Albatross in the vicinity of the Goto Islands in the preceding year. In 1908 it was 

 recorded from the dredgings of Mr. Alan Owston's yacht, the Golden Hind, in Sagami 

 Bay. In 1909 it was again recorded, this tune from the investigations of Captain 

 Suensson in the vicinity of the Goto Islands. 



In 1922 Dr. Torsten Gislen recorded 3 specimens from near the Goto Islands where 

 they had been dredged by Dr. Sixten Bock in 1914. Of these 3 specimens, as he was 

 so good as to write me, only the second really belongs to this species, the other 2 being 

 young examples of Perometra diomedeae. 



In 1927 Dr. Gislen recorded a further specimen from Dr. Th. Mortensen's 

 collections off Kiu-Shiu hi 162 meters.
