We describe the eggs of Rossia pacifica S. S. Berry, 1911, from a depth of
1,200 m off of southern California. The large size of the eggs and the grea
t depth and low temperature from which they were retrieved contrasts strong
ly with smaller eggs of this species taken in shallower, warmer water along
the western coast of the contiguous United States. This raises questions a
s to whether more than one taxon in the genus Rossia is present in this are
a.
