COEVUS BRACHYRHYNCHOS Brehm 

 There occur in the Potter Creek collection a nearly perfect 

 humerus and the distal end of a tibiotarsus which correspond 

 perfectly with the existing phase of this species. The position in 

 the deposit indicates their origin from two different individuals. 



CYANOCITTA STELLEEI (Gmelin) 

 A single perfect tarsometatarsus represents this species of 

 jay in Samwel Cave. In comparing with a specimen of the 

 subspecies C. s. carbonacea, the only noticeable difference lies 

 in the slenderness of the fossil. The length is exactly the same, 

 the degree of slenderness is so slight as to seem negligible in 

 the determination of the species. In Hawver Cave there occur 

 four specimens which show the same slenderness of build. 



EUPHAGUS CYANOCEPHALUS (Wagler) 

 Seven specimens of this species occur in the collections from 

 Ilawver Cave. Several limb bones and a coracoid serve to 

 establish the specific identity. This bird is entirely wanting 

 in the deposits of the other caves.
