^riu* pterylosis of this genus is typical of the <piails and shows very 

 phiiidy the characteristics already mentioned. Although there is no 

 dorsal apterium, the feathers between tin* shouhbu-s are fewer and 

 much weaker than fartluM- back or on the neck. There* ari* 11 (some- 

 "tinu^s 15) secondaries. The claw on the thumb is well developed. The 

 rectrices are iilways 12. Nitzseh credits the bobwhito with only 115 or 

 ];{ secondaries, but he jjrohahly did not have fresh material and it would 

 be almost, impossihle to determine the number conoctly from a skin.
