Ophiomusilt]m jolliense. 

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

 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.
