 spotless are of frequent occurrence. They measure from -60 to *75 

 in length, and from *45 to - 55 in breadth.

The eggs of this large race of A. troglodytes, known as the St. 

 Kilda Wren, in the Collection, are of a creamy-white colour, spotted 

 and blotched with reddish, chiefly at the larger end, and in a bolder 

 manner than is usual with those of the ordinary species. They are 

 also unmistakably larger, measuring from '70 to '77 by from 

 •52 to -59.

The eggs of the Faroe Island Wren resemble those of A. troglo- 

 dytes, but are more heavily spotted, and the percentage of unspotted 

 and feebly marked specimens is certainly less than with the typical 

 species. They measure from - 68 to '8 by from *5 to "61.
