 THE BEARDED TITMOUSE. 



Calamophilus biarmicus. 



PANURUS, K. L. Koch-^. Bill short, subconical, upper mandible convex above, 

 decurved from the base, broader and considerably longer than the lower, which is 

 almost straight : the edges of both somewhat inflected and not notched. Nostrils 

 basal, oviform, pointed in front and partly covered by reflected bristly feathers. 

 Wings with ten primaries, the first almost abortive, the third longest, but the 

 fourth and fifth nearly equal to it, the second shorter than the sixth and about 

 equal to the seventh. Tail very long, graduated and cuneiform, of twelve weak 

 feathers rounded at the tip and slightly decurved. Legs with the tarsus long and 

 scutellated in front ; feet stout, the anterior toes almost free, the outer toe per- 

 ceptibly shorter than the inner ; claws rather long and stout, not much hooked. 



THE beautiful bird here figured was also simultaneously 

 separated from the genus Parus by Koch and Leach, and 

 the careful generic diagnosis given by the former entitles 

 the name Panurus bestowed upon it by him to preference 

 over that of Calamophilus applied by the latter, who left
