264 W. Lilljeborg on the Genera Peltogaster and Liriope. 
very small, forming a sort of minute plate concealing the base 
of the last pair of feet. Head a little broader than the following 
segment ; penultimate segment longer than the preceding one, 
coarctate and rounded behind. Beneath the Jateral margins of 
the thoracic segments there are small acuminate appendages, 
bent backwards, which are, no doubt, epimera. 
Eyes usually none; sometimes a reddish-brown one on each 
side (fig. 5): when no eyes are present, there are usually two 
cells, with reddish-brown pigment, in their place. Similar pig- 
ment is seen in several parts of the body, especially behind. 
Antenne of the first pair (fig. 4 a) very small, quadriarticu- 
late, having about five sete, of which two are apical. Antenne 
of the second pair (fig. 4 5) large, half as long as the body with- 
out the apical sete, quinquearticulate, with the third joint longer 
than the rest, and the last jot having three or four apical 
sete, of which one is very long. Region of the mouth produced ; 
oral aperture forming a transverse fissure. On each side of the 
mouth there is a mandibuliform appendage. 
Thoracic feet (fig. 4c) six pairs, attached to the six thoracic 
segments; all, except the sixth pair, similar, but the posterior 
pairs a little longer than the anterior. The five anterior pairs 
somewhat cheliform, with a rather large, nearly oval palm, bi- 
denticulate within, and a curved, acute, apical claw. Sixth pair 
of feet longer and more slender, and not cheliform (fig. 4d) ; 
palm long and attenuated ; claw long, nearly straight, and not 
retractile. 
Abdominal feet five pairs, attached to the five anterior seg- 
ments of the abdomen, all similar, except that the posterior are 
a little shorter; they are biramose, with the scape two-jointed, 
and the branches nearly equal, the outer furnished with three, 
and the inner with two, long, apical, ciliated sete (fig. 4e). The 
last pair, or caudal feet (fig. 4), are larger and stouter, fur- 
nished with several large and strong ciliated sete, and also bi- 
ramose. The scape of these is of one thick joint, obliquely 
excised at the apex, and furnished beneath with one or two 
slender sete. The outer branch is a little thicker and shorter 
than the inner one, and has three stout, curved, apical sete ; 
the inner one is obliquely excised at the apex, and furnished 
with two slender sete. At the base of the mner branch a long 
and nearly straight seta is attached to the scape. 
No intestine could be clearly seen, but in its place there was 
a patch of a brownish and reddish colour, especially behind ; 
and here and there in the body were larger and smaller oily 
vesicles, no doubt the residue of the yelk. 
On comparing this young animal with the Liriope pygmea of 
Rathke, their relation is so close, that the differences, from the
