The resident Bluebird is decidedly larger and brighter col- 

 ored than the true sialis. It is a new subspecies. 



Sialia sialis Bermudensis A. H. Verrill. 



Blue of the upper parts of male brilliant purplish azure, a 

 little brighter on rump; chin light blue. Breast, sides and 

 flanks deep purplish-cinnamon, much darker and richer than in 

 North American specimens. Female more brownish with 

 brighter rump and back than in the true sialis. Edge of wing, 

 at carpal joint, distinctly pure white. 



Length, 6*75 to 7*5 inches; wing, ± to 4*25; tail, 2*75 to 

 3*25. Nest usually built in crevices and holes of cliffs ; eggs 

 usually pure white, rarely tinged with greenish-blue. 



The resident cardinal bird of Bermuda also differs as a sub- 

 species, from the American forms : 



Cardinalis cardinalis Somersii A. H. Yerrill. 



Adult male : Lower parts brilliant orange-vermillion, brighter 

 and more orange than in C. cardinalis. Upper parts are also 

 clearer and brighter, deep lake-red, with scarcely any gray on 

 tips of feathers. Vermillion of checks and crest brighter and 

 clearly defined. Bill deep scarlet. Female lighter than in 

 cardinalis, especially below ; breast buffy yellow ; belly almost 

 pure white ; upper parts clear ashy gray ; crest and ear-coverts 

 strongly tinged with red ; wings and tail nearly as in the 

 male. 



Length, 8'75 inches ; wing, 3'75 ; tail, 4*75 ; culmen, 0'80.
