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 'yO 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 I'D-l by "SO.

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.
