of yellow-gray, and upper markings of a light and dark olive- 

 brown. 



8. One cuckoo's egg was, without doubt, found in a nest of Sylvia 

 alricapilla, which resembled the eggs of that bird, even to the so-called 

 " marks of branding" [" brandflecken "]. I myself found it close to 

 the White Morass in the Banat, South Hungary. 



9. As regards the egg mentioned above, which came from the nest 

 of Hypolais, the following circumstance occurred : — Mr. Braune, the 

 Royal Forester, for a long time observed a hen cuckoo flying to a nest 

 of the chirTchaff, of which he knew the locality, and which already 

 contained several eggs. Fearing lest the nest built by this superb 

 songster, in his garden, might be destroyed by these visits, he on that 

 account shot the cuckoo, in whose ovary ["legedarm"] he found a 

 perfectly formed egg, which, to his great surprise, was coloured exactly 

 like the eggs of Hypolais, and when he came to examine the nest 

 closely he found a similar egg already laid in it. 



10. Two eggs from the nests of Calamoherpe turdina (especially that 

 one which belongs to Count Bodern) show, even in their faded condi- 

 tion, the peculiar olive-green ground colour of the eggs of the great 

 sedge warbler, which for depth of colour are only surpassed by two 

 cuckoo's eggs, taken the one from the nest of Accentor modularis and 

 the other from the nest of Calamoherpe palustris. Less striking is the 

 similarity in regard to the marking. 



11. Eight eggs out of the nests of Calamoherpe arundinacea. 

 [Perhaps these are the warblers which, next to Sylvia cinerea and 

 Motacilla alba, bring up the greatest number of cuckoos.] These 

 eggs remind one, both in colour and marking, of the eggs of this bird. 

 Indeed by far the greatest number of cuckoo's eggs which I have seen 

 resembled the eggs of S. cinerea and C. arundinacea, which are so 

 like one another. 



12. We have just mentioned one of the two cuckoo's eggs which 

 were found in the nest of Calamoherpe palustris, which is of a 

 tolerably deep blue-green or verdigris-green [" spahngruner"] colour: 

 it has the characteristic spots, as if of branding, and the deeper as 

 well as the surface markings of the marsh warbler's [" sumpfrohr- 

 sangereier"] egg: I found it myself at the White Morass in Hungary. 

 The other, which is in the collection of Count Bodern, is of a pale 

 ground colour, and moreover has the characteristic markings, though 

 more indistinct and thickly spread over the whole surface. One very
