at the lower end of the hinder margin, and six unequal, strong 
teeth along the anterior margin; the genu and tibia are short, 
the carpus stout, with a coarsely serrated process, a little longer 
than the metacarpus. The metacarpus is broad, serrated on 
the outer and inner margins; the dactylus is strong fully as 
long as half the metacarpus. 
. The second pair (Fig. 18) are more than twice longer than 
the first. The femur is long, linear, coarsely denticulated along 
both margins, much longer than the following joints together. 
The carpal process is longer than the basal part of the car- 
pus, coarsely serrated along the outer and hinder margins, a 
little longer than the metacarpus, which is almost linear, serra- 
ted along the inner margin. The dactylus is strong, shorter 
than half the metacarpus. 
The third and fourth pairs (Fig. 19) are coarsely serrated 
along the hinder margins of the four first joints and finely serrated 
along the hinder margin of metacarpus. The fourth pair are a 
third longer than the third. Dactyli of both pairs are long and 
terminal. 
The fifth pair. The femur is long, ten times longer than 
broad, serrated along both margins, the lower anterior corner 
is produced into a sharp angle. The three following joints are 
smooth on the hinder margins, but coarsely serrated along the 
inner. The metacarpus is smooth on the hinder margin and 
finely serrated along the anterior, it is shorter than the carpus. 
The dactylus is long, almost straight. The fifth pair are longer 
than whole the animal (20:17). 
The sizcth pair (Fig. 20) are like the ffth but a fourth 
shorter; the metacarpus is shorter than the carpus. 
The seventh pair (Fig. 22) equal only a third of the length 
of the fifth. The femur is almost linear,serrated along both mar- 
gins. The two following joints are smooth. The carpus is 
smooth on the hinder måärgin, carrying some long hairs, the an- 
terior margin is coarsely serrated; the lower end is bordered all 
around with long stiff hairs. The metacarpus is scarcely lon- 
ger than the carpus, linear, smooth on the hinder margin, 
serrated along the anterior, with some hairs on the sides. The 
dactylus is strong, curved, terminal, equalling a fifth of the 
length of the metacarpus. 
Branchial sacks (Fig. 21) are attached at the bases of the 
fourth, fifth and sixth pairs of pereiopoda.
