350 SMITHSONIAN MISCELLANEOUS COLLECTIONS VOL. 1 37 



Originates on the posterior rim of the coxa vera immediately op- 

 posite the insertion of the posterior sternocoxal muscle (14, b). It 

 inserts distal to the coxotrochanteral articulation on the posterior rim 

 of the trochanter and so acts as a levator. 



d. Anterior coxal depressor of trochanter. 



Other names are: Depressor of the trochanter (Snodgrass), 

 branch of depressor of trochanter muscle (Bonhag), intracoxal de- 

 pressor of trochanter muscle (Miller, m Demerec). 



Originates on the anterior rim of the coxa vera mesad to E, 13, b. 

 It inserts, along with E, 12, and E, 13, e, on the depressor tendon of 

 the trochanter and acts as a depressor of the trochanter. 



e. Posterior coxal depressor of trochanter. 



Other names are: Depressor of trochanter (Snodgrass), branch 

 of depressor of trochanter muscle (Bonhag), intracoxal depressor 

 of trochanter (Miller in Demerec). 



Originates on the lower rim of the coxa, mesially, just above the 

 articulating membrane. Inserts, along with E, 13, d, and E, 12, on the 

 main depressor tendon of the trochanter. 



14. STERNOCOXAL MUSCLES 



There are in Anisopits only two muscles in this group. 



a. Mesial sternocoxal muscle. 



Other names are: Sternal promoter of leg muscle (Snodgrass), 

 ordinary sternal promotor of leg muscle (Maki), sternal promotor of 

 coxa (Bonhag), sternal promotor muscle (Miller in Demerec). 



A large, thin, flat, fan-shaped muscle originating along the edge of 

 the cryptosternum. It inserts on the anterior wall of the coxa vera and 

 must serve to brace the two coxae together in the midline and give 

 them rigidity in relation to the thorax and so enable the furcosterno- 

 trochanter depressor, E, 12, to work with maximum efficiency. 



b. Posterior sternocoxal muscle. 



Other names are : Sternal remoter of leg muscle (Snodgrass), pos- 

 sibly sternal remotor of the coxa (Bonhag), ordinary sternal remoter 

 of leg (Maki). 



Originates on the spinasternum behind the rim of the coxa. Inserts 

 within the posterior rim of the coxa vera immediately opposite the
