THE NAUTILUS. 91 



part wooded and with thick underbrush and tall annuals. On the 

 2(5th Dr. Ortmann and I collected for f\vo hours at Pleasant Valley, 

 Nicholas Co., Ky., in the Licking Valley, on a steep, rocky south- 

 east slope, also limestone. At both places I had no chances to look 

 for minutiae, could do no sifting and brushing. The list of species 

 found is naturally short, and is given below for two reasons: probably 

 no collecting has been done there before, and there were a few inter- 

 esting forms on which some notes are added. It may be noted, by 

 the way, that all of the Polygyree found were represented at Pleasant 

 Valley truly pleasant to the conchologist certainly a large number 

 found on a small spot and in a short time of hurried collecting. In 

 the notes, M stands for Maysville and P for Pleasant Valley. 



Gastrodonta ligera Say. Abundant at M, especially on a loose, 

 old stone wall, a large form, the shells whitish in some specimens, 

 vividly yellow towards the aperture on others. Less common at P, 

 much smaller, the spire higher, and in most specimens dome-shaped. 



Omphalina inornata Say. At P, not common. 



Omphalina Itzvigata perlavis Pi Is. Shell more depressed than that 

 of the common form and smaller; color amber, paler at the base, red 

 dish above; with the soft parts in the shell, the latter appears some- 

 what olive beneath and brownish above; the radial strise above are 

 slighter, less sharp, subregular, and there are no revolving lines; the 

 nucleus has the same stria?, regular, and coarser than those on the 

 upper part of the post-embryonal shell; diam. 17, alt. (total) 11 mill.; 

 in other exs. 15 and 9 mill.; the radula has 29 transverse rows of 

 n) + 18(19) teeth, and there are no perfect admedian, as described 

 by \V. G. B. All specimens were alike except for differences in size. 



Pleasant Valley, Nicholas Co., Kentucky. The snail has not the 

 appearance of 0. laevigata, rather that, of inornata, for which it was 

 mistaken at first sight; but the umbilicus is somewhat wider, and 

 there are other differences, as noted. It agrees in the main with 

 0. I. perfacis, though the color is different. 



Hyalina indentata Say. One specimen at M. 



Agriolimax cumpestris Binney. At both places. 



Circinuria concava Say. Abundant at both places, larger at M. 



Putula ahernata Say. Common at M, large; less common and 

 smaller at P. 



Poly gyro, albolabris Say. A few specimens at P. 



P. zaltta Binney. Not rare at P, mostly empty shells of decidedly
