The eggs of the Rose-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 e^^ described 

 and figured by Owen (/. 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.
