in -the' annexed cut (fig. 116). SteatorniS) -as will be seen 

 (fig. 117), hardly differs, and Podargus agrees with it. In 

 Mgothelejs there is a shght .difference in thai; there is hardly 

 any trace of- the wristward branch of the tendon. Steatornis 

 has an €Xpansor- ' secundariorum^ apparently absent among 

 the-other genera. The imascle is attached to the teres by its 

 long tendon. The insertion of the cZeZ^oicZ is extensive, and 

 it receives a tendon from the scapula.- In inany Gaprimul- 

 gidse the biceps is split for some distance before its insertion, 

 the bifidity even invading the muscle itself and not being

limited to .its- tendon. In Podargus Eurbringer describes 

 a special slip of rhomboideus profundus, arising separately 

 from ilium. The anconaus has a tendinous humeral head. 

 In the thigh the muscle formula is either AXY— (niost Capri- 

 mulgi) or XY— {Steatornis) . The tibialis anticus tendon of 

 Podargus is double. Theglutaeus I. extends over biceps in 

 Nyctidromus, &c., not in .Mgotheles. No glutaeus V. There 

 are sometimes both and sometimes only one of the two 

 peroneals present. In Steatornis and jEgotheles only the 

 brevis is to be found, in Nyctidromus only the longus ; in
