DESCRIPTIONS OF NEW SPECIES 
TERFBRA (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 sculp¬ 
ture 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 ofifset, 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 compres¬ 
sion at the anterior part of the whorl, a smaller initial nuclear whorl 
and fewer revolving striae 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 an¬ 
terior 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;
