As U. americana is the type of Uuspiza, the next name, Hypocentor, 

 proposed by Professor Cabanis, must be adopted. The synonymy of 

 this genus stands as follows : 



Uypocentor Cab.

The Gold-ammer, as this species might be termed, is only of occa- 

 sional and rare occurrence on Bering Island dniing the migration sea- 

 sons. Thus several si)ecimens were shot during the spring of 1882. 

 Kemarkably enough, not a single one was seen dnring the same season 

 of the following year, although 1883 brought such an abundance of rare 

 stragglers. 



Around Pctr(>i)aulski it is one of the commonest summer birds, but 

 seems to anive rather late, as in 1883 it had not made its appear- 

 ance on the 28t]i of May, and before the middle of September most of 

 them had left their northern summer homes again. A single young 

 bird was shot by me on the last day of the same month.* 



It is especially frequent in the eltfer groves on the slopes behind the 

 town, alongside with Carpodacus and Calliope, in comparison with which 

 it is a poor songster, however, its melancholy time strongly contrasting 

 trasting with the merry concert of the others.
