250 BRITISH BIRDS. [vol. vii. 



J. M. Goodall has two sets. Mr. W. Eagle Clarke has also 

 recorded a red set from Foula, and a nest from the Isle of 

 Wight, which was supposed at the time to be that of the 

 Grasshopper- Warbler, probably belonged to this species. 

 There is also a set from Dorset in Mr. H. Massey's collec- 

 tion, and R. J. Ussher's collection in the Dublin National 

 Museum contains two sets from co. Kerry (see Zoologist, 1844, 

 p. 638 : Morey, Guide to Nat. Hist, of I. Wight, p. 502). 



Yellow Wagtail {Motacilla f. rayi). — The late F. Bond 

 possessed a clutch from Freshwater with one pink egg. 



Blue-headed Wagtail {M. f. /lava). — Kricheldorff states 

 that red eggs are very rare [Zeitsch. /. Ool., XIII., p. 11). 



Grey Wagtail {M. h. hoarula). — ^The variety with creamy 

 ground and light rufous markings (resembling some types 

 of Robin's eggs) has been taken in Germany, according 

 to Dr. E. Rey^ and Mr. E. W. H. Blagg took a clutch of 

 this description in Staffordshire in 1904.* 



White Wagtail {M. a. alba). — ^The late Dr. O. Ottosson 

 had a red clutch of eggs taken in Iceland in 1879, which is 

 now in the Swedish National Museum. Seebohm describes 

 {Brit. Birds, Vol. II., p. 201) a type from his own collection 

 as being : " dull white in ground colour, thickly marbled, 

 splashed, and spotted over the entire surface with reddish- 

 brown, and pale brown." 



[Although the true erythristic type is not known to occur 

 in the Lesser Grey Shrike [Lanius minor), some clutches 

 show a tendency in that direction, and G. Krause figures 

 a set with a creamy ground and brown and violet markings, 

 in his Oologia Universalis Palcearctica.] 



Woodchat-Shrike {Lanius s. senator). — Red eggs are 

 rare in this species, but Kricheldorff has received several 

 sets from south Spain, where L. collurio does not breed. 

 The British Museum contains four sets with salmon-pink 

 ground and chesnut and purple-grey markings, from Greece 

 and Asia Minor (Seebohm, Col. Fig., pi. 54) ; Mr. H. Massey 

 has a set from Switzerland, and the red type has also 

 occurred in Algeria (H. B. Tristram). 



CoRsiCAN Woodchat-Shrike {L. s. hoAius). — ^The late 

 John Wliitehead found one clutch of salmon-pink eggs 

 out of some twenty nests examined, and F. C. R. Jourdain 

 obtained a couple of sets in Corsica in 1900. 



* The erythristic type also occurs in the eggs of the Asiatic Grey 

 Wagtail {M. h. melanope), according to Taczanowski (Faune Orn. 

 Sib. Orient., p. 375). A pink egg taken by W. E. Brooks in Kashmir 

 is in the British Museum.
