Ohio^^is minor, Eartl. (p. 1.)* 



Lays two or three eggs, differing much in color [auct. Rev. A. E. 

 Eaton), about January 10, in the crevices formed by fallen rocks. The 

 nest is made of grass-stems [auct. Capt. J. J. Fuller, not seen by J. 

 H. K.). But a single specimen was preserved, given by the Eev. Mr. 

 Eaton, and this was badly broken, but has been mended upon a plaster 

 model. The specimen is regularly oval in shape, like a rather small 

 and narrow hen's egg. Seen under a lens, the outermost calcareous 

 layer appears to be deposited in an irregular net-work, upon a sub- 

 stratum of dark slate-color. The shell is thick and of coarse texture. 

 The superficial markings include several shades of dark sepia-brown, 

 disposed in irregular blotches, but arranged, for the most part, longitu- 

 dinally. These blotches are more plentiful and closely aggregated 

 about the thickest part of the Q.gg than at either end, and overlie a 

 general cafeau lait tint, which proves, under the lens, to be due to the 

 appearance of the dark substratum above mentioned, through the 

 minute areolation of the outer calcareous layer. The measurements 

 are as follows : —

Measurements of eggs are in English inches and decimals. The lengthwise and cross- 

 wise diameters, and, in some cases, the corresponding circumferences, are the dimen- 

 sions given. 

 The structure of the egg-sliell is described as it appears under a Tolles' J-inch triplet.
