structure of the fifth legs in the male. The exceptionally long setae 
on the terminal segments of the maxillipeds will also aid in identi- 
fication.

Buchirella intermedia Wiru, Danish Ingolf-Expedition, vol. 3, pt. 4, p. 124, fig. 
32 a-f; pl. 4, fig. 4 a-c; pl. 8, fig. 3, 1915. 
Stations 3799 ; 3829 ; 3878 ; 4721; 4757 ; 4926; 5120; 5180; 5185; 5190; 
5196; 5224; 5297; 5230; 5233; 5246; 5263; 5287; 5319; 5633. Identi- 
fied by Sars from 35 Monaco stations and listed at two stations in the 
Carnegie plankton but not found in the other lists. This species was 
abundant at station 5319, but only one or two specimens were cap- 
tured at any of the other stations.

Station 5233. A single male and four females of this species were 
found at this station. It appears in the Szboga and Monaco plank- 
tons but not in the others, and some of the Siboga specimens came 
from the Banda Sea not far from this Philippine station. The 
length of the Monaco male was not given, and the Siboga specimens 
were females, but With (1915, p. 127) recorded a length of 6.70 mm. 
for his Danish Jngolf male. This Albatross male was considerably 
larger and measured 7.60 mm., thus approaching the 8 mm. females 
mentioned by With.

Stations 27; 3799; 3800; 4638; 4652; 4679; 4695; 4700; 4732; 4750; 
4926; 5120; 5185; 5224; 5227; 5263; 5319; 5320; 5487. Established 
by Claus upon specimens from Messina and placed in Dana’s genus 
Undina; transferred to the present genus by Giesbrecht (1892, p. 282). 
Identified by Sars from 7 of these Albatross stations and from 75 
Monaco stations; found at 7 stations in the Siboga plankton in verti- 
cal tows from considerable depths and at 3 stations in the Carnegie 
plankton.
