OPHIOCTEN PACIFICUM. 



Lutken and Mortensen, 1899. Mem. M. C. Z., vol. 23, p. 131 ; 



pi. Ill, figs. 5-7. 



These specimens agree well not only with the description and 

 figures of Lutken and Mortensen, but with numerous specimens of 

 jjacifkum from the eastern Pacific and from Japan. They are pec- 

 uliar in the complete absence of spinelets on the basal upper arm- 

 plates and in the great reduction of the arm-comb. But as none 

 are really in good condition, too much stress must not be laid on 

 such negative characters. The specimens measure 6-12 mm. across 

 the disk, and the arms are all broken, usually quite near the disk. 

 The species seems to be abyssal only, in this region, as elsewhere.

This is another deep water species, of very wide distribution. 

 The specimens at hand range from 5 to 24 mm. in disk-diameter. 

 The large specimens are very closely tuberculated, even on the 

 radial shields, while the young specimens are much smoother.
