intervals are crossed by very numerous epidermal lines of growth, in 
the form of thin, raised, very fine lamellae, more or less fringed. The 
canal is a little recurved and narrow; columella somewhat sigmoid. 
Nucleus is very small and regularly spiral; spiral lines begin on the 
first whorl, and the normal sculpture on the second. Length of a 
specimen with five whorls, 10 5 mm ; breadth, 5‘5 mra ; length of body- 
whorl, 8 mm . 
Sipho parvus Verrill and Smith, sp. nov. 
Plate LVII, figukes 20, 20a, 206. 
Shell small, thin, delicate, translucent, subfusiform ; with a rather 
slender, acute spire; a short, straight canal ; and few raised, strong, 
revolving cinguli ; suture impressed. 
Wh oris six to seven, convex, usually with three (rarely five or six) 
prominent, rounded cinguli, or carinse, separated by much wider, 
broadly concave interspaces ; the uppermost one is usually some dis- 
tance below the suture, and is often stronger than the rest, producing a 
slight shoulder; on the last whorl, in specimens with six whorls, there 
are about seven to nine principal carinse, occasionally with a smaller 
one interpolated, and becoming more crowded anteriorly; on one 
with seven whorls, there are thirteen principal cinguli ; fine, delicate 
and close, raised lines of growth, or lamallse, cover the interspaces 
and cross the raised cinguli. The nucleus is very small, smooth and 
glossy; the first turn is minute and regularly spiral, not upturned; 
three spiral cinguli appear on the second whorl. Aperture elliptical; 
outer lip thin, rounded, incurved at the base of the canal, which is 
narrow, but very short, and straight; columella nearly straight in 
the middle. The epidermis is thin, lamellose, but not ciliated. 
Color yellowish or grayish white. Operculum ovate, with the outer 
or left end rounded and incurved, forming a small lobe, defined by 
a notch, and with the nucleus central to this small lobe. 
*Gray’s description of Buccinum Sabinii is as follows : 
“ Canal short , open , bent to the left." 
“Testa oblonga, ventricosa, alba; anfractibus quinque, convexis, longitudinaliter 
costastis ; apertura ovata ; canali brevi.” 
“Shell oblong; veutricose, white; whorls five, convex, slightly longitudinally rib- 
striated, finely transversely wrinkled ; epidermis thin, pale ; aperture ovate, half the 
length of the shell, ending in a. short open canal; columella smooth, outer lip thin, in- 
side slightly crenated; axis, three-fourths of an inch, diameter three-eighths. It 
differs from Buccinum corneum (Murex corneus Lin.), by not being so long and 
slender, and the whorls more convex; the aperture ovate instead of roundish-ovate. 
The specimen brought home appears to be young.”
