Attention has already been called by Mr. G. M. Mathews 

 (Birds of Australia, IV, pt. 3, June 23, 1915, p. 202) to the real 

 status of the generic name Dysporus lUiger as merely a substi- 

 tute name for Sula, and this name has now been displaced by 

 Moris Forster. The name Crypturus, however, which has an 

 exactly parallel status, being a substitute and therefore an 

 absolute synonym of Tinamus Latham, must likewise be 

 rejected, and another name be sought for the group to which it 

 has commonly been applied. Two of the species of this group, 

 Tinamus tataupa Temminck and Crypturus parvirostris Wagler, 

 have been generically separated by Brabourne and Chubb 

 (Ann. and Mag. Nat. Hist., ser. 8, XIV, October 1, 1914, p. 322) 

 under the name Crypturellus, and because this name was found 

 to be preoccupied, later as Microcrypturus (Chubb, Bull. Brit. 

 Ornith. Club, XXXVIII, No. CCXXIX, December 29, 1917, 

 p. 30). Since these two species are generically different from 

 the others commonly referred to the genus Crypturus, and since 

 apparently there are no available synonyms, a new name must 

 be provided for Crypturus Auct. nee Illiger. We propose, there- 

 fore, to call the group Crypturornis,! nom. nov., with Tetrao 

 cinereus Gmelin as type. 



On account of this change the species and subspecies of this 

 genus will stand as follows : 



Crypturornis cinereus (Gmelin) 



Crypturornis macconnelli (Brabourne and Chubb) 



Crypturornis berlepschi (Rothschild) 



Crypturornis castaneus (Sclater) 



Crypturornis obsoletus obsoletus (Temminck) 



Crypturornis obsoletus cerviniventris (Sclater and Salvin) 



Crypturornis obsoletus griseiventris (Salvadori) 



Crypturornis obsoletus purensis (Chubb) 



Crypturornis soui soui (Hermann) 



Crypturornis soui mustelinus (Bangs) 



Crypturornis soui albigularis (Brabourne and Chubb) 



Crypturornis soui hoffmannsi (Brabourne and Chubb) 



Crypturornis soui andrei (Brabourne and Chubb) 



Crypturornis soui harterti (Brabourne and Chubb) 



Crypturornis soui caquetae (Chapman)
