One hundred and forty specimens. 



Ophiomusium jolliense. 

 McClendon, 1909. Univ. Cal. publ. Zool., 6, p. 36," pi. 1, fig. 2, 3. 



These specimens are very young, with disks little more than 4 mm. 

 across, but their identity seems sure.

 of Ripple Point. 633 fms. Bott. temp. 39.5°. Lt. gy. glob. oz. 



Ophiomusium lymani. 

 Wyville Thomson, 1873. Depths of the sea, p. 172, fig. 32, 33. 



It is remarkable that no specimens of this common and very wide- 

 spread deep water brittle-star were taken by the Albatross on either 

 the 1899-1900 nor the 1904-05 expedition. The present specimens 

 are very young and were taken in 1891.
