ANATOMY OF PHtENICOPTERUS. 



647 



The foregoing account, without making any pretence to complete- 

 ness, may serve as a standard of comparison in considering the myolo- 

 gical affinities of the Flamingo. 



In the fore limb this animal agrees so closely with the Storkg 

 that it would be useless to go into any detailed description of its 

 wing-muscles. 



The most important points of agreement, however, are the features 

 of the pectoralis major and of the tendons of the tensores paiagii. 

 In Storks it is well known that the pectoralis major is divided into 

 two or more layers, easily separable from one another, and that its 

 attachment to the humerus forms a tendinous arch beneath which 

 the brachial muscles pass from the coracoid to the arm. la 

 Pkoenicopterus Gadow^ has shown that these features are exactly 

 repeated ; and in Plate LX. fig. 7 I have drawn a specimen in 

 which it seems as if there were actually two distinct great pectorals 

 I need hardly point out that this condition is absolutely unknown 

 among Lamellirostres.

Diagram of tenaores patagii m PhoDiicopterus. 



The tensores patagii form in Pkoenicopterus almost exactly the 

 same figure as that found in Storks, as will be seen at once by com- 

 paring fig. 2, E with Plate LX. fig. (i ; while in the Duck, for 

 example (see Plate LX. fig. 8), there is a marked difference from this 

 type, neither tendon sending a slip down to the flexor carpi radialis, 

 and the whole triangle of the patagium being filled by a strong, even 

 aponeurosis.
