at their distal ends attach themselves to auything- whicli crosses 

 their path; walls of tracheae {TR), tubules of the coxal gland, or 

 to other muscle buiidles. 



Diag-ram C. 



Galeocles (? Othoes). Frontal view. 



Shows in a general way the disposition of the coxal glands. 



The saccnle (iS) and coUecting tubule passiug iuto the labyrinth sac (S.L) 

 (only partially drawn; the posterior extension is omitted) which changes to the 

 coiled tubule of the labyrinth (CZ). The tubule [GL) runs posteriorly and then 

 anteriorly again to the exit tubule {ET), terminating in the nozzle (NZ). In 

 this species there is a definite tubule beyond che nozzle Avith its side outlet (SO) 

 and final outlet [FO) not far from the opening of the rostriim to the exterior. 



In the diagram the tubule has been drawn pointing a little too much inwards. 

 It should have been drawn more obliquely. (Compare with photo 8.) The rostrum (B) 

 with its suckiug Chamber lies in front, and the sucking Chamber passes posteriorly 

 into the uarrow Oesophagus between the two lobes of the brain (dottedovals). 

 The straight dotted iine above indicates approximately the level at which the 

 chelicerae project from the body above appendage II.
