resemblance to those of the genus Mimus than to those of Toxostoma, 

 the surface-markings being fewer and larger, and in some examples 

 fainter than those on the typical eggs of T. rufum, though the 

 form and size of the egg and the ground-colour do not show any 

 divergence. They measure from *90 to I'll in length, and from 

 69 to -81 in breadth.

The single egg of the Arizona Thrasher in the Collection is of a 

 rather broad blunt oval form ; the ground-colour is pale bluish grey ; 

 the rather faint surface-markings, which in the form of spots and 

 blotches are gathered together somewhat thickly at the larger end, 

 are of a pale lavender-grey beneath, and of a soft rosy-brown 

 above. It measures 1-04 by -80.

Eggs of the Mexican Brown Thrasher are, as a whole, inseparable 

 from those of T. rufum, though the two from Matamoras (Salvin- 

 Godman Coll.) are less densely spotted and show more of the pale 

 bluish ground-colour than the rest. They measure from *95 to 1*15 

 in length, and from *75 to *81 in breadth.
