ceedingly delicate, hyaline, pearly white, and very slender. 

 I sent this shell to Dr. Dall in 1887, with the suggestion that 

 it might be a different species, but he responded with some 

 specimens, effectually disposing of even the variety exile. 

 If one of these forms is to carry a name, there are several as 

 well entitled to do so. By far the more scientific method is 

 to write all there is of Carychium under exiguum. 



53. Ferussacia subcylindrica Linn. Of general occurrence 

 here, in same station as last et al, but nowhere abundantly. 

 The shells are larger than those of the same species found 

 about Cincinnati. In Winter, and in dry hot weather of 

 Summer, the aperture is closed by a white opaque epiphragm. 



54. Helicina occulta Say. I have found this species some- 

 what rarely. The shells are more carinate than the typical 

 occulta, and are of all shades of color, varying from bright 

 yellow to greenish, through shades of light buff to white, and 

 through darker shades to brown and red. 



The station was on damp rocks and about them, under a 

 slight covering of leaves. With them occurred a variety of 

 the following species, the two being mixed indiscriminately. 



I have hundreds of specimens of this Helicina from other 

 localities, all of a dull red or brick color. Not a single speci- 

 men exhibits any approach to the fine tints found here. I 

 shall be glad to correspond with any collector having well- 

 marked varieties of this shell to exchange, as my experience 

 has been, previous to finding this colony, that this species 

 exhibits a maximum uniformity.
