Genus — LILJEBORGIA. 
Liljeborgia. Spence Bate, Cat. Amph. Crust. Brit. Mus. p 118. 
Generic character. Cephalon but slightly produced ante- 
riorly. Superior antennae furnished with a secondary appen- 
dage. Gnathopoda large, suhchelate, second larger than the 
first, inferior carpal angle anteriorly produced. Posterior pair 
of pleopoda biramous. Telson cleft. 
The head is not anteriorly produced to half the length 
of the first joint of the superior antennae. The seg- 
ments of the body are nearly as long* as those of the 
tail. The eyes are large. The superior antennae shorter 
than the inferior, and furnished with a secondary ap- 
pendage. The first two pairs of legs have the hands 
largely developed, the second being the larger, and the 
inferior angle of the wrist is produced to a short dis- 
tance along the inferior margin of the hand. The other 
legs are tolerably free from hairs, and have the fingers 
very straight. The last pair of caudal appendages have 
two branches, and the central tail-piece consists of a 
single plate, which is cleft at its apex. 
This genus is named in compliment to the distin- 
guished zoologist of the University of Upsala, Professor 
Liljeborg. 
* The length of a segment is measured in the same direction as that of 
the body of the animal ; the breadth is when it is measured from side to 
side.
