Genus PTYONOPROGNE, Reichenb. 



The eggs of the Rock-Martins are all of the same type and hardly 

 separable from one another. They are of a somewhat lengthened 

 oval shape, and exhibit a moderate amount of gloss. The ground- 

 colour is white, speckled and spotted, and at times blotched, with 

 brownish red or chestnut and underlying grey or lavender. The 

 markings are almost invariably dense and more or less confluent at 

 the broad end, where they form an irregular zone or imperfect cap.
