Summary. 



1. The fifth cubital remex of Carinate birds is abnormally 

 absent, except in the Passeres, Opisthocomi, Hemipodii, 

 and Crypturi, and in some Picarise, Gallinse, and Alectorides. 



2. In the Picarise it is generally present, except in some 

 Cypselidse and Alcedinidae. 



3. In all the Gallinae it is present except in the Megapodes. 



4. In the Alectorides it is generally absent, except in 

 Psophia, Cariama, and Rhinochetus. 



5. Both the dorsal and the ventral tectrix major of the 

 fifth cubital remex, when it is absent, are fully developed. 



6. We know of no intermediate stage between the full 

 development of the fifth cubital remex and its entire absence.
