Brewster on a Collection of Arizona Birds. 205 
u . ft emir A No nests were found, but a female shot May 17 was 
laying. 
In my preliminary announcement* of the occurrence of this species in 
Arizona I inadvertently gave the number of specimens as eight, whereas 
nine were really obtained. These show little variation in color or mark- 
ings, but the females are slightly smaller than the males. The characters 
which separate M. lawrencii from its respective allies, M. tristis of Ja- 
maica and M. nigricafiillus of Central America, are well maintained in 
this series.
