These specimens range in size from those 3 mm. across the disk to 

 those 11 mm. They agree well with the descriptions and figures of 

 Liitken and Mortensen, and comparison with some of their Panamic 

 specimens confirms the identification. It is noteworthy indeed to 

 find this species on the Japanese coast. 



AMPHIURA SUNDEVALLI. 



OphiolepissundevalliMiJLLER and TROSCHEL, Sys. Ast., 1842, p. 93. 

 Amphiura sundevalli LJUNGMAN, Oph. Viv., 1866, p. 320. 



Localities. Alaska, Corwin coll., 1 specimen; Bering Strait, 12 

 fathoms, gravel, 2 specimens. 



The specimens measure about 10 mm. across the disk and are well 

 preserved. There seems to be no room for doubt as to their identity 

 with European and Greenland specimens, so that we have here still 

 another apparently circumpolar species of ophiuran.
