Station No. 5082. — Two medium-sized specimens. 



Station Wo. 5083. — Fifteen large specimens. 



Eudiocrinus japonicus was found at depths of from K));] to 712 

 fathoms (mean 388 fathoms) with bottom temperatures ranging- from 

 37.5^ to 56.0° F., the mean being 43.5'^ F. The largest specimens 

 (arm 125 mm., longest cirri 6-t mm.) are from station No. 4958, where 

 E. varians was not found; but examples from station No. 5083 are 

 nearly as large (arm 100 mm., longest cirri 42 nmi.), and were asso- 

 ciated with large individuals of the other species. 



The two species were found associated at the following stations: 



E. varlans only was found at- 



E. jajjonicu.s only was found at- 



The type of E. varians was ol)tained in 16 - 42' north latitude, 119^ 22' 

 east longitude, in 1,050 fathoms, and that of E. japonicus in 34"^ 7' 

 north latitude, 138'^ 0' east longitude, in 565 fathoms, the temperature 

 in the case of the former being 37^^ and in the case of the latter 38.1^; 

 while the natural inference would be that E. varians was an abyssal 

 form inhabiting very cold water and E. japonicus a comparatively 

 shallow-water form, the data here given suggests that in reality both
