Dr. Th. Mortensen's station 15, Sagami Sea, Japan; 720 meters [Gisl6n, 1927]. 



Geographical range. — Southeastern and southern Japan, from off Kinka San (lat. 

 38°12'50" N.) southward and westward to the Kii Channel (Linschoten Strait). 



Bathymetrical range. — From 128 to 1073 meters; the average of 6 records is 475 

 meters. 



Thermal range.— From 3.83° C. to 13.50° C; the average of 4 records is 7.98° C. 



History.— The first specimen of this species to come to light was dredged by the 

 Albatross off southern Japan on May 8, 1900, at sta. 3706. This was sent, together with 

 the other crinoids collected in that year, to Dr. Hubert Lyman Clark, then at Olivet 

 College, who later most generously turned it over to me. The ne.xt specimen, a 

 remarkably perfect one, was collected by Prof. Franz Doflein in 1904 at the entrance 

 to Tokyo Gulf. 



From the dredgings of the Albatross in 1906 off the eastern and southern Japanese 

 coasts I described in 1907 Antedon mariae, A. laodice and A. hondoensis, the two fii'st 

 based upon smgle mutilated individuals from each of two stations, the third based upon 

 a series of 10 from two stations. 



Considering the enormous abundance of the other species of Floromeira in favorable 

 localities, it is rather curious that at 4 out of the 7 localities at which this species has been 

 dredged onlj- one individual should have been obtained, while at the other 3 the num- 

 bers were only 2, 2 and 8. 



In 1918 I decided that hondoensis was the same as mariae; laodice I maintained as a 

 distinct species uniting with it, erroneously as I am now convinced, rathbuni. I further 

 remarked that laodice may prove to be the same as asperrima, and mentioned some speci- 

 mens from the Gulf of Alaska (herein included under serratissima) , which seemed to be 

 referable to mariae, stating also the possibiUty that serratissima, which is probably 

 only a spinous form of perplexa (here so considered), will eventually prove to be a 

 synonym of mariae.
