Aeaticula are hatched as early week of June; thirdly, the effect which climate, soil, and food may have upon the young, according to the latitude in which they are batched—those which are re ensis) being generally finer and stronger birds than those as the first week of April and as late as the first ared in the north (arguing from what has been observed of other species, for example Alauda arv reared further south. «Were the peculiarities noticed be necessary, upon the same principle, to separate the Savicola enanthe and some others. “The question would then arise, ‘ Where is the line between species and variety to be drawn?’ in other ‘n this case considered sufficient to constitute them a species, it would words, ‘ What constitutes a species ?’—a question which is not easily answered.” Touching this subject, Mr. Robert Gray, in his ‘Birds of the West of Scotland,’ remarks :—* The variation in the size of this species has been a source of much perplexity to me. In the spring-time I have shot so many much smaller than the Ringed Plover which breeds with us that I have long thought, seeing they only appear in spring, that they must belong toa southern race. . © 7 V0 e 5 a » . . . 2 ar nS < ‘ , From the above passage it is evident that the smaller Dottrel visits Scotland; and that the other one also does, I am certain; for the largest and finest skins I have in my collection were taken from specimens killed in Orkney and sent to me by the late Mr. J. H. Dunn. Speaking of the habits of Aigialitis hiaticula, Mr. Gray goes on to state :—‘* I have nowhere been sh interested with this bird than in the Outer Hebrides, a district throughout which it abounds at a > x or re , F ae » NN - % S seasons of the year.
