“Pastor Theobald has an egg from Russia said to be of this bird, which resembles fine-spotted 
eges of Parus ceruleus, but is more elongated and almost as large as eggs of the Great Tit- 
mouse.” 
The figures in the Plate represent the old and young birds of this beautiful species, taken 
(as are also the descriptions) from specimens in our own collection from Siberia, the adult male 
having been given us by our friend Mr. Carl Sachse, the young bird having been procured near 
Lake Baikal by Dr. Dybowski in May 1869.
