The eggs of the Eose-throated Becard in the Collection vary from 

 a narrow to a broad oval shape, are devoid of gloss, and are of three 

 types of coloration. Those of one type resemble the egg described 

 and figured by Owen (Z. c), which is cream-coloured, densely marked 

 ■with lines, scrawls, and spots of purplish-pink and clouds of lilac. 

 Of a second type are eggs of a pinkish-buff ground-colour, marked, 

 chiefly at the broad end, with blotches, scrawls, and spots of umber- 

 brown and purplish grey. Eggs of the third type are of a pale 

 creamy-buff colour, sparingly spotted all over with pale greyish 

 brown. Specimens measure from '91 to -96 in length, and from 

 •65 to "7 in breadth.
