PHASIANELLA VARIATA, Lyc. Tab. XLV, figs. 28, 28 a, 3. 
Testa ovato-elongata, spira acuta, anfractibus (6-7), subconvexis, latiusculis, suturis valde 
mmpressis, ultimo anfractu amplo, apertura obliqua, ovato-elongata. 
Shell variable in figure, ovately elongated ; spire lengthened, with the apex acute; volu- 
tions six to seven, wide, more or less convex ; the sutures strongly impressed ; the last volu- 
tions conformable, the aperture oblique, ovate, narrow, but always less than half the height 
of the shell. ‘ 
The variability in the convexity of the volutions and their height i8 considerable. The 
general aspect resembles P. elegans, Mor. and Lyc., in which the spire is always less 
pointed and less slender, the last volution being also longer.

SoLariuM TURBINIFORMIS, Zyc. Tab. XLV, figs. 23, 23 a, 6. 
Testa turbinata, spira dextra, elevata, obtusa, anfractibus (4), tubereulis numerosis, coro- 
natis ; basi eonveva, umbilico magno, margine, nodis (circa 9) cingendo, superficie lineis 
transversalibus et longitudinalibus decussatis ; apertura suborbiculari. 
Shell turbinated, spire dextral, elevated, volutions four, their borders coronated with a 
circle of tubercles, about eighteen in a volution ; the base is convex, with a large and 
deep umbilical cavity, bordered by large nodose elevations, about nine in the volution ; the 
aperture is suborbicular; the entire surface has encircling lines, with more narrow inter- 
stitial spaces decussated and rendered granular by densely arranged transverse striations. 
Allied to Straparollus altus, D’Orb.; the latter species, however, has the last volution 
more elevated and the sides much more flattened, which impart a subquadrate figure to 
the aperture; the nodose elevations encircling the umbilicus are also fewer and larger.
