two diameters apart, and separated from the laterals a little 
more than a diameter ; posterior medians much smaller than 
the anteriors, widely separated from them, closer to posterior 
laterals, which are about as large as the anterior laterals and 
separated from them by a space which is quite equal to the 
long diameter of the latter. 
Protarsal scopula of i. covering less than half the segment, 
with a weak spine at its base ; of ii. as on 1., with 2-2 spines 
at its bases; of iii. covering a little more than distal third, 
with many stout spines at its base; of iv. covering about }, 
which is elsewhere strongly spined ; tibia of all the legs 
spined ; tibiz of the pedipalps unarmed. Protarsus 1. very 
slightly bowed at its proximal end; spurs of tibia 1. well 
developed, the upper stout, straight, cylindrical, blunt ; the 
lower crescently cylindrical, curved, with a stout blunt spine 
on its apex and a long spine at base.

19. Grammostola longimana, sp. n. 
3 .—65 mm.; ceph. 26 x 26 mm.; legs 103, 88, 77, 91 mm. ; 
femur i. 28°5 mm., iv. 24 mm.; patella+tibia i. 39 mm., 
iv. 29 mm. ; protarsus i. 24 mm. 
Carapace black. Falces black, with mahogany-browna 
bristles. Legs blackish, with ochraceous-reddish bristles aul 
with two longitudinal pale lines on the upper side. Abdomen 
wholly black, with erect, large, ochraceous bristles. Sternuin 
and coxe reddish black. Coxee of pedipalps and inner margin 
of fang-groove with pale red-wine bristles. 
Carapace as long as wide, its length considerably less than 
patella and tibia iv. or i., a little less than femur i., longer 
than femur or protarsus iv. ; fovea deep, a little recurved. 
Ocular tubercle very high, nearly round. Eyes of anterior 
row strongly procurved, the anterior edge of the medians 
heing a little behind the posterior edge of the laterals, nearly 
evenly spaced and a little unequal in size, the medians being 
the smaller and separated from. each other about two 
diameters ; posterior medians much smaller than the anterior 
medians, closer to posterior laterals, which are a little smaller 
than the anterior laterals, and separated from them by a space 
which is larger than the long diameter of the latter. Sternum 
as wide as long, the posterior sigille separated from the 
margin more than a diameter. 
Stridulating organ as in the preceding species. Legs 
1, 4, 2, 3, the anterior legs being considerably longer than iv. ;
