COPEPODS GATHERED BY ALBATROSS—WILSON 235 
ent also in the Siboga and Carnegie planktons, but nowhere in 
abundance, 
Genus GAUSSIA Wolfenden, 1905 
GAUSSIA PRINCEPS (T. Scott) 
PLATE 11, Figures 117-119 
Pleuromma princeps T. Scott, Trans. Linn. Soc. London, ser. 2, Zool., vol. 6, pt. 1, 
p. 42, pl. 3, figs. 8-20, 1894. 
Stations 2; 4; 4539; 4542; 4679; 4687; 4707; 4717; 4758. Identified 
by Sars from 6 of these Albatross stations but not found in any of the 
plankton reports. This is a very large copepod and easily recognized 
by the peculiar asymmetry of the genital segment. Since figures af 
the two sexes have appeared together only once the excellent drawings 
made by Sars are here reproduced. ‘The color of this copepod is very 
dark, almost black, with the ventral surface of the genital segment a 
reddish brown. [See remarks under J/etridia atra. | 
Genus HALOPTILUS Giesbrecht, 1898 
HALOPTILUS ACUTIFRONS (Giesbrecht) 
Hemicalanus acutifrons GIESBRECHT, Fauna und Flora des Golfes von Neapel, 
monogr. 19, pp. 384, 398, pl. 3, fig. 11; pi. 27, figs. 4, 12, 18, 26; pl. 42, figs. 12, 
20, 1892. 
Stations 3834; 4634; 5240. Identified by Sars from the second of 
these 3 Albatross and from 22 Monaco stations and found at 15 stations 
in the Carnegie plankton but not in the other lists. 
HALOPTILUS ANGUSTICEPS Sars 
Haloptilus angusticeps Sars, Bull. Inst. Océanogr. Monaco, No. 101, p. 20, 1907; 
Rés. camp. sci. Albert de Monaco, No. 69, p. 246, pl. 72, 1925. 
Stations 5120; 5190; 5288; 5240. Established by Sars upon speci- 
mens from the temperate Atlantic and the Mediterranean and fully 
described and figured in the Monaco plankton. It was also reported 
from the Pacific in the Carnegie plankton. 
HEALOPTILUS BULLICEPS Farran 
Haloptilus bulliceps Farran, Journ, Linn. Soc. London, Zool., vol. 36, No. 243, 
p. 286, pl. 9, figs. 15, 16; pl. 10, figs. 1-3, 1926. 
Station 5246. [The discovery of a single female of this Biscayan 
species in the Philippines was recorded by Dr. Wilson in his list of 
identifications of the Albatross plankton but not referred to in his 
manuscript text of this report. It is of interest to note that Farran 
secured six specimens in the course of 5 to 21 tows made at 100 fathoms 
in the Bay of Biscay, and one specimen in one of six hauls made 
between 200 and 100 fathoms. The unique Albatross specimen
