302 ON THB iNATOMX OF EHTNonops. [Feb. 18, 



halves, that which abuts upon the patagium, is chiefly tendon, 

 there being a belly of only about half an inch in length, strung as 

 it were upon a long thin tendon. The inner half of the muscle, on 

 the contrary, is muscular almost to its insertion. 



I did not succeed in finding any traces of the expansor secun- 

 dariomm, for which as a characteristic muscle I looked carefully. 



The deltoid is not extensive. Its humeral attachment occupies 

 rather more than the first third of that bone. It ends exactly on 

 a level with the end of the attachment of the anterior section of 

 the latissimus dorsi. 



The anconceus longus, in addition to the partly fleshy and partly 

 tendinous origin from the coracoid, has a lougish and entirely 

 tendinous scapular head ; it also is bound down to the humerus by 

 a broad tendon. 



In the leg-muscles the most remarkable divergence from the 

 Larine character is in the total absence of the ambiens (on both 

 sides of the body). 



The femoro-caiidal is present and has a long tendon of insertion. 



The accessory femoro-caiidal is broader than the latter, is entirely 

 fleshy, and joins it some way before its insertion. 



The semitendinosus with its accessory are present. 



There is nothing remarkable about the hiceps or setnimem- 

 hranosus, 



Tliere is only one peroneus, whose tendon joins that of one of 

 the superficial long flexors. 



The deep jkxors blend entirely about halfway along the meta- 

 tarsus ; the conjoined tendons give off no slip to the small hallux. 



§ Syrinx. 



The syrinx of Bhynchops (fig. 3) is a perfectly typical tracheo- 

 bronchial syrinx with a single pair of intrinsic muscles.
