THE NAUTILUS. 143 



window the week before an outcrop of limestone at the railroad 

 bridge across the Chipola river, one mile east of town, that I wanted 

 very much to examine, so before train time, the next morning, I 

 made a grand rush for the river. The nummulitic limestone con-' 

 tained but one mollusk, Pecten perplanus, but what it lacked paleon- 

 tologically, it made up malacologically in furnishing a suitable en- 

 vironment for numerous species of snails. A glance showed it to be 

 an ideal collecting ground ; limestone, moisture, a varied vegetation, 

 a cave and an old quarry with moss-covered rocks in all directions, 

 is just what the snails want, and visions of a new species or variety 

 formed an active stimulant; for I felt sure that Hemphill, Ferriss or 

 Sargent had not been there. But alas, while the snails were thick, 

 a nov. sp. was not to be found by " dis chile." Ferriss would no 

 doubt have found one, for I still believe it's there. Pyramidnla 

 alternate/, was very abundant, a coarsely sculptured and beautifully 

 marked form, among which I found a sinistral specimen. P. per- 

 spective was also plentiful; neither of these have previously been re- 

 corded from Florida. Among the leaves in front of the cave were 

 numerous fine specimens of Gastrodonta demissa, the majority of 

 which are slightly more depressed than the typical form. Ompha- 

 lina laevigata chiefly frequented an old log, while Helicina orbiculata 

 were found among the rocks in the drier portions of the quarry. A 

 few specimens of the following species were also obtained : Glandlna 

 truncata, Zonitoides arboreus, Yitrea indentata, Strobilops labyrinthica, 

 Bifidaria armifera, Polygyra inflecta, P. appressa var. perigrapta, 

 and P. stenotrema. The latter species have not before been recorded 

 from Florida. In the river drift near the bridge were numerous 

 specimens of Polygyra auriformis and a few Succinea hiteola. As this 

 drift was not the direct wash of the river, but was formed by the 

 water hacking up over the low ground along the railroad, I am in- 

 clined to think that the two species could be found living among the 

 grass and sedge along the high-water mark. 



EPIPHRAGMOPHORA HARPERI, N. SP. 



BY F. W. BRYANT. 



Shell unbilicate, translucent, white; suture well defined; spire a 

 depressed cone composed of five regularly increasing convex whorls, 

 the first three smooth, the remainder marked by obscure, closely- 

 crowded, oblique lines of growth; base convex; aperture nearly 

 circular, oblique; peristome thin, broadly expanded, and reflexed at 

 lower third of baso-columellar portion, its extremities joined by an 

 elevated ridge, bordering which is a somewhat triangular callus 

 bounded on the inner side by a ridge extending from the middle of 

 the base of the reflected portion of the peristome obliquely to the
