The enormous size of the feel and length of the hind claw of this 

 bird render ii easily distinguishable from any other of the bnerican 

 Ground-finches, and seem to necessitate its generic isolation. The 

 plumage, moreover, is exactly that of the Buarremotu

Dr. Hartlaub has correctly pointed out the differences between 

 this species and G. mexicanus, which, as he rightly observes, is the 

 only other known species of the genus ; and the figure in the " Ge- 

 nera of Birds" is good. It is certainly curious that Geococcyx 

 •nexicanus, which is common in California, should cross the centre 

 of the continent (occurring in New Mexico and Texas), and pass 

 down the eastern slope into Vera Cruz, while in the southern part 

 of the western slope and in Guatemala, this bird appears to take its 

 place. Dr. Gambel has some excellent remarks on these birds in the 

 Transactions of the Academy of Philadelphia, i. p. 21 7.

This appears to be identical with the bird of the United State-. I 

 have never seen the (so-called) second species Z. margineUa ( Wbod- 

 house).
