Bulima conoidea Kk. & S.* 
Cedar Keys, on mud flats between tides, not common. This agrees 
with the diagnosis of the species cited, but I have not seen an authentic 
specimen of Kurtz and Stimpson’s shell. 
Bulimelila s). indet. 
Cedar Keys. A small pinkish-white and very pretty shell. 
Bulima (Leiostraca ?) hemphillii n. s. (Plate X, Fig. 4.) 
Shell slender, straight, acute, brilliantly polished, black when fresh 
(when faded, or by transmitted light, dark claret brown), with nine or 
ten flattened whorls; sutures appressed, nearly invisible except by 
transmitted light; aperture rounded in front, pointed behind; outer lip 
slightly thickened, passing imperceptibly into the inner lip, which is 
slightly twisted; shell rather thin and without noticeable deposit of 
callus. Lon. of shell, 3.00; of last whorl, 1.60; of aperture, 0.57; max. 
lat., 1.00™™, 
Habitat.—Cedar Keys, mud_flats between tides, six specimens only. 
This very beautiful little sheil appears to be in all respects, except 
color, a typical Hulima, but forms a remarkable exception to the glisten- 
ing white which is so uniformly characteristic of the other species 
known. When first received they appeared absolutely black, but the 
color is less dense than at first, though still nearly black. Many of the 
species of Hulimella or Leiostraca have bands of color on the shell, and 
it is possible that this one may belong rather with them than with the 
typical Eulimas. 
Obeliscus tesselatus Adams. * 
Cedar Keys mud flats, between tides, abundant. I have not been 
able to compare specimens of Adams species. This is probably what 
is referred to as O. terebellum by Sowerby and Melvill; it is certainly 
not that species nor the crenulatus of Holmes. It is not at all 1mprob- 
able, however, that the O. dolabratus (=terebellum) may turn up in South 
Florida, as it is commom in the Antilles. 
Pyramidelia ? vinctan.s. (Plate X, Fig. 7.) 
Shell elongated, slender, subeylindrical, apex pointed, with a minute 
pellucid smooth sinistral half-immersed nucleus and ten or twelve 
strongly spirally sculptured whorls. Color whitish (specimens all dead, 
one immature, one fresh); spiral sculpture begins with two strong 
elevated ridges with deep channels between them and separating them 
from the ridges of the next whorl; the posterior ridge is crowded with 
strong fig-shaped nodules with the broad ends backward and axes par- 
allel with the axis of the shell; the anterior ridge is not nodulous; on 
about the fifth whorl from the nucleus the nodulous ridge becomes 
double and the figs become oranges, or round nodules, which later are 
even somewhat elongated in the direction of the ridges; the other 
ridge remains simple and suz9oth; at the periphery of the base are two
