Korean SDK near the Goto Islands; 33"? 10' N. 
lat., 1299 18' E. long.; 40 fathoms; Suensson, September 
17, 1900. Three specimens; the largest may be described as 
follows: centro-dorsal a thick disk, the moderately large polar area 
slightly convex, the cirrus sockets arranged in two and a partial 
third crowded and irregular, more or less alternating, rows. 
Cirri XXXV, 31—35 (usually nearer the latter), 20 mm. to 
25 mm. long; first joint short, the following gradually increasing 
in length to the sixth — eleventh or fourth — fifteenth which are 
squarish or somewhat longer than broad, then very gradually de- 
Creasing in length, though never becoming much broader than long; 
rather prominent dorsal spines developed from the tenth joint on- 
ward; opposing spine rather short and blunt. 
Thirty-nine arms 65 mm. long; the outer side of the I Br and 
further division series bears a rather broad band of fine granulations, 
which narrows anteriorly, disappearing on the last axillary or first 
brachial; a much narrower band is found between the II Br series, 
and traces of a similar band between the III Br series. At the 
time I described this species, this very noticeable character, in some 
unexplained way, was overlooked, though I find it to be one of the 
best means of identifying the species. On reexamining the type, 
I find that it is quite as marked in that as in the present spe- 
cimen, though, because of the very light colour, not quite so evident 
at first glance. 
One of the smaller specimens possesses two IV Br series, 
developed externally. 
Korean Straits, off the Goto Islands; 33? N. lat., 
1299 24' E. long.; 22 fathoms; Schånau, August 16, 
1891. One small specimen.
