quum, 2 (108/,); a. the exterior, radiately striped 
wall of the spiracle, b. the aperture of the spiracle, 
e. the opening of the trachea in the respiratory 
cave shining faintly through. 
The interior wall of the respiratory cave of the 
distal spiracle in P’hal. propinquum (1917/1). 
A piece of integument of tibia with the conical 
spines and the distal spiracle (in Phal. propin- 
quum 7) of the same pair of legs as the proximal 
spiracle exhibited in fig. 5 and drawn with the 
same enlargement. The conical spines on these 
two figures may give an idea of the relative size 
of the different portions of the spiracles, and both 
figures being drawn with the same enlargement, 
you get at the same time a correct conception of 
the relative size of the 2 spiracles on the same 
leg. c. the opening of the trachea in the respi- 
ratory cave. 
2 clavated hairs from the last joint of the palpus 
in Nemastoma lugubre O. F. Müller (c. 400/,) 
exhibited Tab. III, fig. 15; a. hair showing the 
interior structure, b. hair, showing the surface. 
A piece of the metatarsus of the 3d right leg of 
Phalangium parietinum Degeer, då, seen from in 
front (42/1); a. bunches of particular hairs, each 
of which bunch is like a clavated hair when seen 
with a slight enlargement. 
2 bunches of hairs from the metatarsus of the ist 
pair of legs in the male of Phal. parietinum (25/,). 
The basal joint of the mandible in the male of 
Chelifer granulatus C. Koch, seen from below 
and from the inside (142/,); a. lamina interior, f. 
»flagellum«, b. lyriform fissure. 
The 2d joint of the same mandible as in the 
former figure (142 |); ge. galea, s. serrula.
