Korean Straits, off the Goto Islands; 33709 N. lat., 
129? 18' E. long.; 40 fathoms; Schonau, May 23, 1898. 
One specimen. 
No locality. One specimen, small, with an externally de- 
veloped IV Br series. 
Formosa Channel; 35 fathoms; Suensson, November 
23, 1901. One small, though well developed, specimen, with 
only four rays, which bear seven, four, three, and six arms re- 
spectively. The disk is lacking so that orientation and the deter- 
mination of the missing ray is impossible. The specimen is very 
imperfect; the longest cirrus stump remaining, broken off at the 
nineteenth joint, is 12 mm.; the longest arm, broken off at the 
tenth brachial following a III Br series, is also 12 mm.
