Stations 7; 15; 470; 3799; 4687; 5120; 5129; 5185; 5227; 5246; Fiji 
Islands. This species is the type of the genus H'uaetideus established 
by Sars in the Monaco plankton; specimens from three of these 
Albatross stations were identified by him. It was found at seven sta- 
tions in the Monaco plankton, nine stations in the Siboga plankton, 
and was reported from the Pacific in the Carnegie plankton.

Euaugaptilus angustus Sars, Rés. camp. sci. Albert de Monaco, No. 69, p. 281, 
pl. 91, 1925. 
Stations 4671; 4691; 4695; 4717; 4719; 5320. Identified by Sars 
from the first 5 of these 6 Albatross stations and from 16 in the 
Monaco plankton but not appearing in the other lists. It was first 
reported from the Pacific area by Sewell (1932, p. 322).

Stations 4687; 4717; 4782; 4740. Identified by Sars from these 
Albatross stations in the eastern Pacific and from 20 stations in the 
Monaco plankton; also found at 2 Stboga stations. 
EUAUGAPTILUS ELONGATUS (Sars)

EHuaugaptilus elongatus Sars, Rés. camp. sci. Albert de Monaco, No. 69, p. 270, pl. 
84, 1925. 
Stations 5225; Fiji Islands. Established by Sars from 21 stations 
in the Monaco plankton and reported by Farran (1908, p. 71) as 
Augaptilus elongatus off the coast of Ireland, but not occurring in the 
other plankton lists. All the previous specimens have been taken 
from the Atlantic Ocean, and this is the first Pacific record. 
EUAUGAPTILUS FACILIS (Farran) 
Augaptilus facilis Farran, Fisheries Ireland, Sci. Invest. for 1906, pt. 2, p. 73, 
pl. 3, figs. 28, 24; pl. 8, figs. 1-6, 1908. 
Station 4717. Identified by Sars from this single station near the 
Galapagos Islands, and in the Monaco plankton from a single station 
near the Canaries, but not appearing in the other lists. Farran’s 
original specimens and others reported on by Wolfenden (1911, p. 
343) were all from the Atlantic. Sewell’s record from Indian waters 
(1932, p. 822) may be the first Pacific one, as these specimens are prob-
