* The name of- rufus is founded on Daubenton's plate {I. c). As in the 

 case of many other Piiiits, the figure is very inaccurate, and the description 

 of Montbeiliard does not agree well ; but, on the whole, it seems to have been 

 taken from a specimen of the small American Pipit, which is common in Bra- 

 zilian collections. The colour of the tail, which ought, of course, to be the 

 distinguishing characteristic, is described as follows : — "Tail-feathers brown, 

 ed"ed, the right centre ones with clear ruibus, the two outer pairs with white ;" 

 and the entire length is given as " five inches and a quarter." In Daubenton's 

 plate the tail has only seven feathers, and none of the external ones are present.
