 DESCRIPTIONS OF NEW SPECIES
 TEREBRA (AcUS) KISSIMMEENSIS N. SP.
 Plate I, Figures 9 and 10
 Shell solid, polished, attenuated, conical with about 13 (including 3 nuclear) whorls; nuclear whorls smooth and rounded; axial sculpture on first 4 post-nuclear whorls of about 15 rounded riblets extending unconstricted from suture to suture; later axial sculpture terminating near the center of the whorl as slightly offset, rounded tubercles below which the whorls are somewhat spirally excavated between the central tubercles and another opposing and similar set crowding the suture; spiral sculpture of 3 to 4 narrow impressed lines on earlier whorls, increasing in number on later whorls, all weakly overrunning the axials; suture distinct, narrowly grooved and flexuous; base with two pairs of distinct impressed spiral lines, the upper set being nearer together. Canal short; outer lip missing.
 Cotypes (Cat. No. 352280 U. S. N. M.). These measure: the larger specimen (7 whorls),-alt. 12 mm., greatest diameter 3.6 mm.; smaller specimen, alt. 9 mm., greatest diameter 3 mm.
 Type locality: Well (depth 65-100 ft.) at Kissimmee, Osceola Co., Fla., Geo. C. Matson, collector, 1908.
 Geologic horizon: Probably Miocene.
 This species is related to Terebra (Acus) concava (Say), but differs from the latter in having no distinct subsutural band, a spiral compression at the anterior part of the whorl, a smaller initial nuclear whorl and fewer, revolving stria on the base.

 COLUMBELLA (ALIA) MATSONI N. SP.
 Plate I, Figures 3 and 4
 Shell small, solid, about six-whorled (tip decollated) ; spire smooth, elevated, evenly conical; whorls slightly convex, marked by three or four narrow, dim, brownish colored, spiral bands, slightly elevated on the anterior portion of the body whorl; suture somewhat appressed; shoulder of body whorl angled; base and pillar marked by thirteen wide, rounded, raised bands separated by narrow channels, running parallel with and extending nearly to the angled shoulder; aperture moderately wide;
