Ch. — Head very small. Bill short, black; ciilnien onc-thiid the rest of the head. Tarsi very short, half covered ante, 

 riorly by feathers. Inner lateral claw much larger than outer, reaching to the base of the middle one. Tail very lung and 

 excessively cuncate ; about as long as the wings. First primary lungest. 



This genus is readily distingui.shed from the other Golumhinae by the excessively lengthened 

 and acnte middle feathers. It formerly included tlic Columha carolinemis, but this, with 

 more propriety, has been erected into a different genus^ and will be found in tiie next section.
