502 MR. C. WITH ON PHALANGIIDE 
Var. UNISPINOSA. 
2. Scutum has only one long spine ; in one specimen there is 
a little spine in front of the long one. Tubercle smooth. Legs 
long. 
iB 1=12)(60) S26 i Vi IG: 
Colour brown with black spots, or with the last segments of 
the cephalothorax darker. Antenne yellow. Palpi yellowish- 
brown. Legs brown. 
3. Tubercle bears a few teeth above; tarsi bear an inner row 
of about 20 teeth, placed rather far apart. Cephalothorax black 
or blackish-brown ; the scutum brown with a black spine. 
Three free dorsal segments black in the front, yellow-brown 
bebind. Underside blackish. 
The Danish ‘ Galathea’ Expedition has taken three specimens 
from the “ Little” and three from the “ Large ’’ Nicobar. 
Though the var. wnispinosa is somewhat different from the 
main type, I prefer at present to place them in the same species. 
The characters which distinguish them seem to be fluctuating, 
as, for instance, the length of the legs, the armature of the 
scutum, and the tubercle. When we have acquired richer 
material from the different islands of the two groups, it will be 
possible to estimate better the value of these differences. 
GAGRELLA PLEBEIA (Thor.). 
Thorell, (40) 1889, p. 659. (Melanopa plebeia.) i 
Lateral parts of the ventral segments partly granular. Tarsi 
of the males smooth. The two specimens, which are mounted 
as Thorell’s original specimens in the Museum at Copenhagen, 
are very different with regard to the femora of the legs. The 
femora in one resemble those of an ordinary Gagrella, but in 
the other they are very odd. 
The femora of especially the fourth pair of legs are very 
thick and gradually thicken from the base to the extremity, 
the outer and under sides are strongly curved inwards; and it 
is probably such femora which suggested to Thorell the genus 
Melanopa. 
GAGRELLA TRISTIS (Thor.). 
Thorell (10) 1889, p. 662. (Melanopa tristis.) 
Palps of the males with the usual tarsal row of teeth.
