The eggs of the beautiful Hooded Warbler 
(Myiodioctes mitratus ) do not show as great a 
variation in size and coloring as those of many- 
other species of Warblers, but still the study of 
a series of them will reveal many differences. 
The following series of eleven sets were all 
collected by the Hon. John N. Clark, with the 
exception of Set II, which were taken by Mr. 
Arthur T. Wayne. 
Set I. May 27, 1887. Saybrook, Conn. Four 
eggs, fresh. Creamy white, speckled at the, 
larger ends with dark reddish brown and lilac. 
The markings are principally confined to the 
larger ends: .GGx.51; .G9x.52; .G8x.53; .09 x 
.52. 
Set II. June 7, 1880. Charleston, South Car- 
olina. Four eggs, fresh. White, quite glossy. 
Marked with specks of lilac and reddish brown, 
and a few spots that are almost black, which 
form indistinct wreaths near the larger ends, 
and leave the remainder of the surface immac- 
ulate: .70x.54; ,70x.55; .09 x .53 ; .72x.55. 
Set 111. June 6, 1887. Saybrook, Conn. Four 
eggs, fresh. Creamy white, speckled and spot- 
ted more or less all over the surface with very 
light reddish brown, as well as a few spots of a 
darker shade of brown, and lilac. The mark- 
ings are closer together near the larger ends, 
where they form indistinct wreaths: .G8x.53; 
.70x.54; .G8x.53; .70x.55. 
Set IV. June 4, 1885. Saybrook, Conn. 
Three eggs, fresh. Creamy white, and quite 
glossy ; two of them are marked with a profu- 
sion of specks and spots of bright reddish 
brown and lilac, which are principally at the 
larger ends. The third egg has very light red- 
dish brown and lilac spots, in the form of a 
wreath at the larger end: .74x.54; .74x.55; 
.72 x .54. 
Set V. May 31, 1887. Saybrook, Conn. Four 
eggs, fresh. Creamy white, speckled and spot- 
ted with light reddish brown and lilac. The 
markings arc larger and thicker at the larger 
ends: .71x.55; .70x.55; .G8x.53; .6Sx.53. 
Set VI. May 20, 1887. Saybrook, Conn. 
Four eggs, fresh. White, speckled and spotted 
with reddish brown and lilac, chiefly at the 
larger ends, where they form wreaths: .G7x 
.52; .69 x .53 ; .70x.55; .G5x.54. ‘ 
Set VII. May 28, 1878. Four eggs. White, 
spotted and speckled with dark reddish brown 
and lilac. The markings are almost wholly at 
the larger ends, where they form indistinct 
wreaths: .71x.54; ,71x.55; .75 x .50 ; .73 x .55. 
Set VIII. June 3, 1880. Saybrook, Conn. 
Four eggs, fresh. Glossy creamy white, quite 
pointed for this species. Marked entirely at 
the larger ends with light and dark reddish 
brown and lilac spots and specks. The mark- 
ings are more at the larger ends of the eggs in 
this set than in any others in the series, and 
when looked at from the smaller ends the eggs 
appear entirely unmarked. This is a very odd 
effect, and the writer has never seen another 
set of eggs of any species which lays marked 
eggs in which this curious phenomenon is ap- 
parent. It is caused by the markings being 
confined to the very tops of the larger ends, 
and the largest circumference of the eggs at 
their broadest point being entirely unmarked 
it prevents the spots at the tops from being 
seen: .75x.53; .73x.54; ,72x.53 ; .73x.55. 
Set IX. June 4, 1886. Saybrook, Conn. Four 
eggs, slightly incubated. Creamy white, quite 
heavily wreathed near the larger ends with 
bright reddish brown and lilac: .70x.54; .71 x 
.52 ; .69 x .52 ; .G8 x .61. 
Set X. May 27, 1887. Saybrook, Conn. 
Four eggs. Creamy white, with some gloss. 
Wreathed near the larger ends with spots of 
bright reddish brown and lilac, with a few dark 
reddish brown ones ; the remainder of the surface 
of the eggs is immaculate: .68x.52; .72 x.53; 
.70 x .53 ; .08 x .53. 
Set XI. June 4, 188G. Saybrook, Conn. 
Four eggs, fresh. Creamy white, beautifully 
wreathed near the larger ends with very bright 
reddish brown and lilac — the latter color being 
almost imperceptable in some of the eggs. 
This is decidedly the handsomest set in the 
series: ,70x.55; -G9x.55; .69 x .54 : .69 x .55.
