THE NAUTILUS. 91 



part wooded and with tliick uiult'ibrusli and tall annual?. On the 

 2r)tli Dr. Ortnia'Mi and I colU'clcd for two Iujuis at Pleasant V«lley, 

 iNi(hoIa.s Co., Ky., in llir LickiM;^ Vaili-y, on a steep, rocky south- 

 east slope, also lime-tone. At both places I had no chances to look 

 for minutiae, coidd do no silting and brushing. The list of species 

 found is naturally short, and is given below fur 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 l^olygyrcB found were represented at Pleasant 

 Valley — tridy pleasant to the conchologist — certainly a large number 

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

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



Gnstrodoutn liijera 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 higlier, and in most specimens dome-shaped. 



OmphtiUna inornata Say. At P, not common. 



OnipJittlina Icevifjuta perlcEvis Pils. 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 striie aljove are 

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

 nucleus has the same striie, regular, and coarser than those on the 

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

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

 m + 18{ 19) teeth, and there are no perfect admedian, as described 

 l)V "W. G. B. All specimens were alike except for dilferc m-es in size. 



Pleasant V^alley, Nicliohis Co., Kentucky. The snail has not the 

 apj)earance of 0. Iceviyutn, rather that of inorwita, for which it was 

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

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

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



Ihjaltna inrleutcUa Say. One specimen at M. 



Ayriolimax cnn/iestris Binney. At both places. 



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



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

 smaller at P. 



Piihj'jyra alboluhris Say. A few specimens at P. 



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