Crested Lark (Galerida cristata). Two typical clutches 

 of five from Hungary. 



Short-toed Lark {Calandrella hrachydactyla). Two 

 clutches of five and three of four eggs, all typical, from 

 S. Russia and Montenegro. 



White-winged Lark (JMelanocoryplia sihirica). Two 

 typical clutches of five from S. E-ussia. 



'Qi,KQK-ljk.ViK(^Melanocorypliayeltoniensis). Three clutches 

 of four from S. Russia, showing two distinct forms, i. e., 

 closely mottled and blotched ; these closely resemble certain 

 forms of A. arvensis in the arrangement and colour of 

 the markings ; they are, however, larger. Measurements : 

 average twelve eggs, 25'4 x 17'3 mm. ; weight 228 mg. 



Shore-Lark [Ot.ocorys alpestris). Two clutches of five, 

 and five of four each, from Finland, Russian Kola, etc. 

 On the whole, these eggs are rather distinctive ; in shape 

 they resemble those of L. arhorea^ colour distinctly 

 ochraceous. 



White Wagtail [Motacilla alba). Ten clutches from 

 Sadowa, Geneva, Saxony, etc. There are no distinguishing- 

 characteristics by which these could be separated with cer- 

 tainty from those of M. luguhris, though when a series of 

 each is placed side by side, the former are, on the average, 

 distinctly more brownish. 



Pied Wagtail {Motacilla lugubris). A representative 

 series embracing practically every known form and variety. 

 Eggs with large superimposed markings were shown in this 

 and the former series ; also clutches distinctly capped, with 

 the lower portion almost unmarked — c/j with pure white 

 ground rather boldly marked was exceptional. 



Grey Wagtail {Motacilla hoaruld). A very beautiful 

 series of twenty -five clutches showing great variation. 

 Conspicuous among them was a clutch of six with leucitic ten- 

 dency, a clutch of six distinctly erythristic, and a clutch of five 

 very heavily zoned, probably unique. Clutches with well- 

 defined superficial markings are a distinct break away from 

 the typo-eggs, which are usually finely mottled. 



Yellow Wagtail {M. raii). A series of 20 clutches.
