Nitzsch's figure of Ficus viridis. This woodpecker is so 

 far much more hke a parrot. 



In Jynx the interior part of the dorsal tract forms a 

 continuous Y, of which the fork is hardly wider than the 

 handle. This is completely discontinuous with the median 

 posterior portion of the tract. 



The tensores patagii ' are very simple. The tendon is 

 single. There is a conspicuous cucullaris patagialis, but 

 no biceps slip. Each tendon, both longus and brevis, is 

 reinforced by a tendon from the pectoralis. In Centurus 

 striatus the slip to the longus is muscular in origin ; it 

 seems to be more usually tendinous. 



The deltoid is an extensive muscle. 



The latissimus dor si posterior appears to be totally absent, 

 as in Indicator. 



As to the leg muscles, the accessory femoro-caudal is 

 always absent. The femoro-caudal and the semitendinosus 

 are always present ; the accessory to the latter may or may 

 not be present, its occurrence in different genera being 

 shown in the following list : —
