Cingula Sandersoni Verrill, sp. nov. 
Shell moderately large for the genus, thin, fragile, long-ovate, with 
a rather tall, somewhat turreted, acute spire. Whorls six to seven, 
strongly and evenly convex, separated by a deep, impressed, simple 
suture. Body-whorl large, rather swollen, well rounded, and con- 
stituting more than one-half the length of the shell. Nuclear whorl 
small, smooth, somewhat prominent, regularly coiled. Base rather 
strongly produced, destitute of an umbilicus, but sometimes with a 
slight chink, produced by the everted edge of the inner lip. Aperture 
pretty regularly ovate, rather broad, obtusely rounded in front, and 
with the posterior end narrowed and sometimes forming a slight 
sutural sinus; outer lip thin and regularly curved; inner lip con- 
tinuous, usually with a thin, free edge along the body-whorl. The 
sculpture consists of very fine, close revolving lines, visible with a 
lens, and of still finer, but usually distinct lines of growth, which 
interrupt, more or less, the spiral lines. 
Color white in our specimens, all of which appear to have been 
dead when dredged. 
Length, 4™™; breadth, 2"; length of body-whorl, 2:5"; length 
of aperture, 1°8™". A large specimen, with broken apex, is 2°7™™ 
broad; length of body-whorl 3°5"". Most of the specimens are 
smaller than those measured, and some are more slender in propor-_ 
tion. 
Station 2109, off Cape Hatteras, in 142 fathoms, numerous speci- 
mens (No. 35,447). 
In form, this species resembles C. turricuda Lea, but the latter is 
described and figured as smooth and umbilicated. It is evidently 
allied to C. aculeus, but differs in its stouter form, deeper suture, 
and much finer sculpture. The sculpture is somewhat similar to 
that of C. leptalea, but the latter is very different in the form of the 
shell and aperture. Dedicated to Mr. Sanderson Smith, by whom 
it was dredged. 
Rotella cryptospira Verrill, sp. nov. 
Shell minute, strongly depressed, with the spire not at all elevated 
and mostly concealed by the overlaping of the last whorl. Surface 
smooth and polished, without any lines of growth. The last whorl 
constitutes nearly the entire shell, overlaping and nearly concealing 
the previous whorls, but sometimes leaving a slight central depression 
in which the minute spire is imperfectly visible. Base flattened or 
but slightly convex; the umbilical region is completely covered by a
