ing turn nipple-shaped, with a small eccentric projecting apex ; 
the length of the pullus equalling once and a half the width of 
the next following turn of the spire. Each turn of the spire 
embracing the next preceding one at the suture, near which they 
are concave, then forming a convex shoulder and nearly parallel 
with the axis of the shell below; body-whorl fusiformly narrowed 
in front, and marked with a broad siphonal notch, without an- 
terior crest or ridge. Inner lip excessively thin, moderately 
spreading ; plaits of the columella four, widely separated, very 
prominent, narrow, one smaller, Aperture moderately wide, 
oblong, narrowed above and below, becoming effuse with age. 
Pullus smooth ; the next two turns of the spire with exces- 
sively fine spiral strize, only visible with the lens (about ten or 
eleven in the space of 1 line) ; rest of the spire and body-whorl 
smooth or marked with fine lines of growth. Length of pullus 
4 lmes, width of ditto 3 lines; length of adult (including the 
pullus, which is 3 lines) 6 inches; proportional length of body- 
whorl -+3;; length-of wing ;22;; width of body and wing 73%; 
width of body on inside of base of aperture 58.8;. 
There is no living or fossil species at all like the present in 
the large, thin, angular, wing-shaped outer lip and fusiform 
body. Young specimens an inch and a half long are irregularly 
fusiform, of two whorls in addition to the pullus of nearly two. 
The layer of shell bearing the microscopic spiral striz seems 
very liable to fall off, leaving the whorls only marked by the 
lines of growth. 
Not uncommon in the passage-beds of the tertiary sands,

Voluta Hannaford (M‘Coy). 
Fasciolaria Hannafordi, olim, MS. 
Broad, fusiform ; pullus at apex of spire, very large, smooth, 
spheroidal, of little more than one turn and a quarter; spire 
conical, apical angle 70°, of four whorls (besides the pullus), 
each obtusely angulated in the middle and bearing on the angle 
from twelve to seventeen large nodose tubercles, obtuse and 
conoidal on the body-whorl, on which the smaller number is 
found, more elongate on those of the spire, on the upper of 
which the greater number occur ; the oblique space between the 
tubercles and the suture marked with narrow, slightly undulating, 
thread-like, spiral ridges, irregularly alternating in thickness; 
below the tubercles the body-whorl is smooth or marked with 
obtuse lines of growth as far as the anterior extremity, which is 
marked by thick obtuse spiral striz crossing the lines of growth; 
but the young whorls or vertical portions of the smaller turns 
of the spire are marked with spiral striz slightly larger and less
