Genera and Spectes of Trapdoor Spiders. 189 
distal half with about 40 spicules arranged in from four to 
six transverse rows. 
Sternum piriform,’ flat, a little longer than wide, widest 
between the coxe of the second and third legs, the scars 
(impressions) indistinct; a pair of long oval indistinctly 
defined scars in the posterior half of the plate and about as 
far from each other as from the margins of the sternum. 
Legs 4, 1, 2, 3, the first and second pair much stronger 
than the third and fourth, and with their distal segments 
(patella, tibia, &c.) furnished below with a clothing of long 
woolly hairs; femora with normal hairs; the tibiee, protarsi, 
and tarsi flat below, convex above, with a marginal external 
and internal row of stout close-set spines; the third and 
fourth legs not spiny, apically slender,and not flattened 
below; all the legs furnished above with hairs arranged in 
longitudinal lines; on the third leg the femur has a large 
triangular membranous area in the distal part of its lower 
surface ; the anterior surface of the patella 1s covered thickly 
with short spiniform sete, and similar short spinules are to 
be observed upon the distal end of the tibia, which has a 
smooth, shallow, saddle-shaped depression at its proximal 
end, and an upstanding ridge along its anterior edge. 
The palpt resemble the legs of the first pair, but have no 
woolly clothing below and only one spine upon the proximal 
end of the inner edge of the tibia. Claw of left palp with a 
strong basal tooth, of right unarmed (? broken) ; claws of 
first and second legs with three teeth, of which the middle is 
usually the strongest ; claws of third and fourth leg with one 
long tooth, with an accessory basal denticle on the anterior 
claw on the third leg. 
Abdomen globular, covered with very fine short hairs. 
Median spinners slender, nearly cylindrical; exterior short, 
stout, with the basal segment longer than the second and 
third, the second a little longer than the third and hemi- 
spherical. 
Paramigas subrufus, sp.n. (Pl. V. figs. 1-10.) 
Colour. Carapace and limbs above of a rich reddish black ; 
coxe and sterna clear yellowish red; tarsi deep, almost blood- 
red; abdomen a deep bluish, greyish black. 
Measurements in millimetres.—Total length of trunk 20, of 
carapace 8°5, width 7:3; distance of fovea from anterior 
margin 4°2 ; width of ocular area 3; length of one side of 
angular fovea 1:3. 
Loc. Senbendrana, near Tamatave, Madagascar (Majaster 
Coll.).
