STRUCTUEE AND CLASSIFICATION OF BIRDS 



In Asio otus there is a fleshy slip from pectoral to 

 loDgus tendon, and a fibrous slip from humerus to patagial. 

 muscle just at origin of innermost brevis tendon. In Scops 

 Lempiji there are muscular slips to both longus and brevis 

 from the pectoral, and a fibrous slip from the humerus to 

 the longus tendon just at its origin. 



The humeral origin of the anconaus is always present, 



There is never an expansor secundariorum, so far as 

 is known. 



The pectoralis primus is not at all double. 



The only one of the leg muscles used by Gareod in 

 classification that is present is the femoro-caudal, the 

 formula thus being A—. Glutseus I. is absent, glutseus V, 

 small. In Ketupa'javanensis, however, V. is absent and I. not 

 quite so. Only one peroneal muscle is present, which is 

 attached to head of metacarpal, The tendon of insertion of 

 the tibialis anticus is divided ; in Pulsatrix I found it to 

 be trifid at insertion, and even the muscle itself was divided 

 into two for a short distance. 



The deep flexor tendons are of type I, In Ketupa 

 ceylonensis the two tendons blend a quarter of the way down 

 the tarso-metatarsus ; - though blejided the fibres can be 

 recognised, and it may be seen that those of flexor hallucis 

 mainly supply digits I., II., a small part only to rest. of com- 

 mon tendon.
