The eggs of the Long-tailed Titmouse are of a pointed oval 

 form and have a small amount of gloss. They are of two types 

 of coloration, both apparently equally common. In the first typo 

 1 he egg is plain white ; in the second it is white or pinkish white, 

 speckled and freckled with two shades of pale chestnut or rufous 

 and some faint lavender. The markings are usually denser at the 

 broad end than elsewhere, and sometimes form an indistinct zone or 

 cap at that part. Specimens measure from - 51 to *57 in length, 

 and from -39 to "43 in breadth.

The eggs of the British Long-tailed Titmouse are very numerously 

 represented in the Collection. They vary in shape from a long 

 pointed, to a short broad, oval form, and, as a rule, they possess a 

 small amount of gloss. Like the eggs of jE. caudatus they are of two 

 types of coloration : plain white, and white speckled with rufous 

 and pale purple. The two types, judging from the series in the 

 Collection, are of about equal occurrence. The markings on some 

 examples are very faint and indistinct, but they impart a rosy tinge 

 to the shell. Specimens measure from "52 to '62 in length, and 

 from -4 to *48 in breadth.
