is cream-colour, almost obscured by a dense freckling of dull 

 reddish brown and faint lavender underlying markings. It is 

 worthy of remark that one of each type occurs in the two pairs 

 of eggs from Medellin : one of these pairs was obtained by Salmon 

 with the female bird. 



In size the eggs vary from 1'18 to 1-22 in length, and from '80 

 to -86 in breadth.

An egg of the Costa-Bican Ouzel in the Collection is considerably 

 larger than those of the other South- American Thrushes with which 

 we are now dealing. It is singularly destitute of the usual Thrush- 

 like markings, these being restricted to a few scattered minute dots 

 of reddish lilac on a ground of pale glossy blue. It measures 1*30 

 by -91.

Two eggs of the St.- Vincent Ouzel in the Collection are bluish 

 white, blotched and spotted with light and dark shades of reddish

 1-21 by -85 and 1-3 by -87.
