Eight badly bleached eggs of this species were preserved in 
addition to the two fresh ones previously referred to. All 
were collected on the same day, June 27. ‘They exhibit con- 
siderable variation in form, ranging from nearly oval to ellip- 
tical oval, elliptical ovate, and elongate ovate. The two fresh 
specimens have a dull whitish ground. The larger end of 
each is irregularly capped with more or less confluent spots, 
lines, and blotches of cinnamon-rufous and bay. The re- 
mainder of the shell is speckled with the same colors. The 
specimens measure in millimeters: 99.6x 65.5; 103.4x 72; 
105.4 x 67.5; 107.4 x 68.6; 108.1 x 70.5; 108.4 x 64.4; 108.7 x 
66.5; 108.8 x 6916; 111.7 x 695 1125 ~ 68:7,
