* The species so named by Stephens, together with P. undatus of Temmiuck 

 and P. undums of Cuvier, may possibly be referred to Picoides americanus, but 

 liaving been founded upon Erisson's "Pic mrie do Cayenne" which iu itself 

 appears to be a coiubiiiatiun of two species (the male being evidently P. ameri- 

 canus and the female P. arcticus), I do not think these names can be accepted.
