AMERICAN GOLDEN-CRESTED KINGLET. 157 



the first row of smaller coverts; the base of all the quills, excepting the 

 four outer, white; from the seventh primary to the innermost secondary but 

 two, a broad bar of blackish-brown. Tail of the same colour as the quills. 



Length 4 inches, extent of wings 7; bill along the back j^-, along the edge 

 yf ; tarsus T j. 



Adult Female. 



The female is somewhat smaller than the male, from which it differs in 

 external appearance, chiefly in having pure yellow substituted for the flame- 

 colour of the crown, and in having less grey on the hind neck. 



If we compare the American Golden-crested Wren with the European, 

 we find that they agree in general appearance, in the proportional length of 

 the quills, and in the form of the tail, as well as that of the bill and legs. 

 Their differences are the following. 



Regulus tricolor is longer by half an inch than JR. cristatus, its bill is 

 stronger and ^ of an inch shorter, its claws are also stronger and shorter, 

 and the flame-coloured patch on the head is more extended and brighter. 

 The European species has never so much grey on the neck and back, and its 

 lower parts are always more tinged with brownish-yellow. The other 

 differences are not very obvious, but the difference in the size of the bill, 

 were there no other characters, would be enough, in a family of birds so 

 closely resembling each other as the Reguli, to point out the American as 

 distinct from the European species. 



Thalia dealbata, Pursch, Fl. Amer. Sept., vol. ii. p. 584.— Gynandria Monandria,

This beautiful plant is a native of Georgia and South Carolina, where, 

 according to Pursch, it was discovered by J. Millington, Esq. of the latter 

 State. It is perennial, flowers in August and September, attains a height of 

 four feet, and grows in swampy places. The leaves are large, ovate, with 

 parallel oblique ribs, and a revolute apex; the flowers are pale purple, in 

 pairs, in a large panicle. I was indebted to Mr. Noisette for the specimen 

 which I have represented.
