 twelfths in length and breadth, the lateral muscles strong, the epithe- 

 lium rugous, the intestine is 6 inches long, its greatest width \^ twelfth,

AMERICAN GOLDEN-CRESTED WREN 



Regulus tricolor, Nuttall. 



PLATE CLXXXIIL Vol. II. p. 476. 



Dr Towksend informs me, that this delicate little bird is an inha- 

 bitant of the Columbia River ; and from its being abundant in Labra- 

 dor and Newfoundland, it is not improbable that it proceeds farther 

 north into the Fur Countries, although no mention is made of it in the 

 Fauna Boreali- Americana. 



In this and the other Reguli, the structure of the digestive organs 

 is the same as in the Warblers. The width of the mouth is 2f twelfths ; 

 the tongue 2^ twelfths long; the oesophagus 1 inch 2 twelfths, its greatest 

 width 11 twelfth ; the stomach oblique, elliptical, 4i twelfths long, 3| 

 twelfths broad, its muscles very thin, the epithelium rugous ; the in- 

 testine 4 inches long, its greatest width 1 twelfth ; the coeca 1 twelfth 

 long, i twelfth broad, 6 twelfths distant from the extremity. The tra- 

 chea 1 inch long, | twelfth broad, flattened, of about 50 rings ; the 

 bronchi of about 12 half rings. The muscles as in the Warblers and 

 Thrushes. . .
