near the junction of the coxopocUte with the paraphragm and is in- 

 serted just ventral to the main branch. It assists in lowering the 

 coxopodite.

dite, this slender muscle travels laterally to its insertion on the proxi- 

 mal border of the epipodite, which it moves slightly inward. 



5*5. Musculus abductor exopoditis II pedis maxillaris (fig. 10). — 

 This muscle arises ventrally in the outer side of the coxopodite and 

 proceeds laterally to its attachment on the median ventral proximal 

 part of the exopodite. It causes the exopodite to move outward and 

 forward.
