62 TROCHXLI. 



Similar to /. latirostris, but with the throat nearly glittering 

 green ^yith scarcely any tinge of bine ; the upper surface is of a 

 rather more coppery hue. 



This is another doubtful species, of which the Museum con- 

 tains a pair from the Tres Marias Islands. Count von Berlepsch 

 says that it occurs at Mazatlau, where /. latirostris and /. magica 

 are also found. The green of the throat is purer than the 

 greenest of the Bolaiios specimens, but that three sucli closely allied 

 birds should all occur at Mazatlan is extremely doubtful. 



Rab. Tres Marias Islands and, according to v. Berlepsch, the 

 opposite mainland at Mazatlan.
