FUSUS SANCTA‘CRUCIS, new species. 
ave reXGXONGIE ii ommeae 
Description.—Shell about 45 mm. in length, slender, fusiform ; 
apex acute. Whorls 6 or 7, convex below, flat to concave above; 
about 12 slightly oblique (sloping downward toward the left), nar- 
row, wave-like ridges extend across each whorl from a short distance 
below the upper margin to the lower margin, becoming best developed 
on the angle of the whorl; a flat, narrow, roughened band forms the 
upper margin of the whorl; surface sculptured by numerous fine, 
equal, equidistant, raised spiral lines, most prominent between the 
longitudinal ridges; suture distinct, slightly wavy. Canal long, nar- 
row, bowed shghtly outward. 
Dimensions.—Length (restored), 44 mm.; latitude, 12 mm.; length 
of body whorl, 30 mm. 
Notes.—This species 1s characterized by its slender form, long 
slender canal, and the equality of its revolving lines. It resembles 
FE. geniculus Conrad from the Oligocene of Astoria, Oregon, but is 
easily distinguished from the latter by its slenderer form and the 
regularity of its spiral sculpture. 7. sanctecrucis is distinguishable 
from F’. hecoxi by its slenderer form, narrower and relatively longer 
axial varices, and equality of the spiral lines; it comes from a con- 
siderably higher part of the formation than the latter. The plasto- 
type, which is figured, shows the spiral sculpture over only a portion 
of the shell. Named for the Santa Cruz quadrangle. 
Type.—l. 8. J. U., No. 1087. (Locality No. 109.) 
Horizon.—San Lorenzo formation, Oligocene, upper portion tran- 
sitional into Miocene. : 
Locality.—Santa Cruz quadrangle, Santa Cruz County, locality 
No. 109, Bear Creek, 4 miles above its confluence with San Lorenzo 
River. (J. F. Newsom.)

Description—Shell about 23 mm. in altitude, broadly fusiform ; 
spire elevated, apex moderately acute. Whorls about 6+, ventricose ; 
upper whorls biangular; body whorl triangular; a prominent nodose 
to undulating, squarish, narrow revolving ridge ornaments the lower 
angle, while a much less prominent ridge surmounts the upper; on
