of anterior tracheal ante-chamber in a dorso-lateral direction 
to tlie body integument on the lateral side. 
12. Longitudinal parietal along ventral integument of 
abdomen. 
13. From posterior intertracheal fold to integument of 
abdomen (many or most of the strands continuous with 12). 
23(7. Longitudinal from x to the spinners, running along- 
side of the abdominal tracheal trunk for the greater part of 
its course and dividing posteriorly into several muscles, the 
lowest of which is attached to the lateral or middle part of 
the anterior side of the mesial anterior spinner (thus appa- 
7-ently corresponding to 27 or 28 in Segestria). 
30. From the apex of the entapophysis pcJ. 8 in a dorso- 
lateral direction to integument of abdomen on lateral side of 
anterior spiracles (inserted immediately behind 11). 
30(7. Longitudinal from the apex of the entapopli 3 ’sis ec.L 8 
to X. (See also PI. 28, fig. 8, m. 30 a.) 
32. From x to posterior side of posterior intertracheal fold 
(inserted at extreme medial end of the spiracle). 
33. From x in an antero-dorsal direction to the oviduct, 
meeting the latter at the point where the muscle ends in the 
figure. (The muscles 23«, 30n, 32, and 33 are continuous 
with each other at x on the lateral side of the abdominal 
tracheal trunk.) 
34. Oblique from medial and posterior side of the common 
basal part {c.fr.) of tracheal trunk to anterior intertracheal 
fold (inserted on medial side of the entapophysis ec f. 8). 
35. From upper edge of posterior intertracheal fold to 
base of anterior intertracheal fold (many strands apparently 
continuous with 13). 
36. Subtransverse from posterior medial edge of anterior 
tracheal pedicel (in a transverse line with the cross x in 
text-fig. 17) to between the upper and lower cephalothoracic 
trunks of the posterior trachea. (See also fig'. 8, m. 36.) 
37. From the spineless, basal, posterior part of the second 
trachea and its lateral pocket in a dorso-lateral direction to 
the integument on the lateral side of the second spiracle
