ROCK THRUSH. 



PLATE CII. FIGURE II. 



Turrfus saxalilis, TEMMINCK. 



Petrodncla saxatilis, VIGORS. GOULD. 



r~TlHE nest is said to be made of moss. It is placed 

 in crevices of rocks, whether those which have 

 fallen down from their primaeval resting-place, or those 

 that still abide in the place of their hoar antiquity. 



The eggs are described as being four or there- 

 abouts in number, and of a greenish blue colour, 

 without spots. 



J. R. De Capel Wise, Esq., of Lincoln College, 

 Oxford, has forwarded me an egg, and Edwin 

 Cottingham, Esq. drawings of two specimens, copied 

 from the original eggs in the museum of J. Malcolm, 

 Esq., Lamorbey, Halfway- Street, near Bexley, Kent, 

 by his permission. These eggs have a beautiful glossy 

 shell, and each of them a clear uniform tint of colour 

 without spots or marks of any kind; the lightest- 

 coloured variety is a trifle larger than the darkest, and 

 not so pure and positive in colour, being of a neutral 

 tone between a light grey and a very slight approach 

 to a light bluish green.
