Stearns.] 9°? [January 17, 
Marginella (Glabella) aurcecincta Stearns. 
Shell small, solid, ovate-conic; spire elevated, rounded at the 
apex; whorls, five, suture indistinct, being hidden by the enamel; 
aperture narrow,-linear, about half the length of the shell; outer lip 
thickened, its internal edge moderately notched above and crenated 
below; surface smooth, polished, white, with two revolving amber- 
colored bands; columella with four prominent plications. 
Measurement: long., .16, lat., .07 inch. 
Habitat: Long Key, on the west coast of Florida, where I obtained 
the single (living) specimen described. An exceedingly beautiful 
shell, resembling in its general features, color excepted, my G. opa- 
lina, but less robust, with a more acute spire; the internal crenations 
of the outer lip less prominent; the columellar plaits less conspicuous, 
closer and more oblique. The color of the bands will quite likely be 
found to vary in different individuals; in my solitary specimen the 
bands are a light, clear amber, golden when seen through the intensi- 
fied light of a magnifier, suggesting the gilded striping on French 
porcelain. 
Drillia ostrearum Stearns. 
Shell small, elongated, slender; spire elevated, sub-acute; whorls, 
seven or eight, concavely angulated above and moderately convex 
below; longitudinally sculptured with (16-20) rounded ribs, incon- 
spicuous on the angle, most prominent upon the extreme convex- 
ity of the whorls, decreasing and becoming obsolete anteriorly; in- 
tersections of sculpture nodulous; suture marked with a thread-like, 
revolving rib; color, dingy yellow to purplish black; aperture ovate, 
narrow, about two-fifths the length of the shell; outer lip thin, with 
a rounded, shallow notch near the suture; columella nearly straight, 
canal short. 
Measurement: long., .67, lat., .24 inch, largest specimen; long., 
.51, lat., .18 inch, smallest specimen; number of specimens, three. 
Habitat: Pine Key, Tampa Bay, west coast of Florida, where I 
found them on bunches of oysters, in a shallow pool overflowed 
by the tides. The sculpture varies in prominence in different 
individuals. 
Mangelia stellata Stearns. 
Shell small, fusiform, turrited, yellowish tinged more or less 
with reddish brown; number of whorls seven, angulated above; su- 
ture distinct; sculptured with twelve to thirteen strong, smooth, 
longitudinal ribs, which extend to the extremity of the basal volu-
