Monops lubbockit GrEsBRECHT, Atti Accad. Lincei, Rome, ser. 4, vol. 5, sem. 2, p. 29, 
1889 ; Fauna und Flora des Golfes von Neapel, monogr. 19, pp. 487, 496, pl. 26, 
figs. 18, 32 ; pl. 41, figs. 60, 63, 68, 1892. 
Station 31. Established by Giesbrecht upon specimens from the 
tropical Pacific and found only in the Carnegie plankton lists. Fig- 
ures of the fifth legs of a male and female obtained from this Albatross 
station off the Galapagos Islands and the grasping antenna of the male 
are here introduced for comparison. The chief specific character 
shown in the fifth legs of the female is the very long and slender spine 
at the tip of the exopod, with a stout spine on each margin at its base. 
In the fifth legs of the male there is a rounded knob at the distal end 
of the first segment of the right leg, two setae on the outer margin 
of the second segment, and the third segment is a stout chela. In the 
left leg the end segment has a distinctive terminal armature. In the 
enlarged portion of the grasping antenna the three proximal segments 
are beveled on the distal side at the outer margin.

Stations 4706; 4765; 5340. Established by Dana upon specimens 
from the tropical Atlantic north of the Equator and reported from 
there in the Carnegie plankton. Reported by Scott in the Siboga 
plankton from the tropical Pacific.

5176; 5223. Identified by Sars from 17 of these Albatross stations 
and from 5 Monaco stations; found in all the plankton lists except 
the Challenger. In the Albatross plankton it is most widely distrib- 
uted, but has never been reported as abundant anywhere. One of the 
females captured at station 8878 in the Hawaiian Islands had a
