COPEPODS GATHERED BY ALBATROSS—WILSON 173 
volume, is annotated “eingeg. 12. August 1897.” In this article Van- 
hoffen admits that the larger account from which the name published 
by Chun was taken was still awaiting publication “in der niichstens 
erscheinenden ‘Fauna und Flora von Grénland.’ ” 
In 1902 Sars (p. 82) revealed that his earlier nomen nudum, Undi- 
nopsis bradyi (Sars, in Schneider, 1894, p. 131), was identical with 
Bradyidius armatus. (In this connection, see also T. Scott, 1900, 
p-. 883.) Disregarding all that had gone before, Sars (1902, p. 33) 
sought to validate the generic name Undinopsis with no more argu- 
ment than that it “ought to be preferred.” 
The Albatross secured some material of both of the species here 
discussed. No attempt is made to give all references in literature 
for either; only the more important synonymy is cited.—W. L. S.]

same time sustaining its precedence over Undinopsis bradyi Sars.) 
[Stations 5185; 5190. Two females of this species, which was pre- 
viously reported from the Atlantic and Pacific, usually from deep 
water, were taken in a vertical haul from 550 fathoms to the surface 
at the first of these two Philippine stations. Although identified also 
from the second station by Dr. Wilson, the specimens on which the 
record is based appear not to have been saved. This haul was also a 
vertical one from 250 fathoms.—W. L. S. ]
