A. E. Verril—Mollusca of the New England Coast. 417 
This beautiful and delicate species is named in honor of Miss 
Charlotte E. Bush, one of the excellent assistants who have aided me 
in my work on the conchological collections of the U. 8. Fish Com- 
mission, 
Gymnobela brevis Verriil, sp. nov. 
Shell small, short, stout, with a short, turreted spire, having 
squarely shouldered lower whorls. The nucleus is eroded in all of 
our specimens, but apparently consist of three whorls, which rapidly 
enlarge, the third having its surface covered with regular spiral lines 
crossed by slight thin ribs; on the next whorl the revolving lines 
become more prominent, about four of them situated below the 
shoulder, which is sloping, and one or two above it ; these are crossed 
by longitudinal ribs of about the same size, producing a decussated 
structure. On the last whorl the spiral lines become thicker and 
stronger and the ribs become stouter, more elevated and obtuse, 
separated by wider intervals, and run down somewhat obliquely and 
fade out at about the middle of the whorl; the spiral lines form 
minute nodules in crossing the ribs; above the shoulder, which is 
strongly angular, the ribs are thin, only little raised, and bend 
obliquely forward without much curvature on the subsutural band, 
which rises abruptly from the suture, sloping but little, and is some- 
what concave in the middle and a: little swollen close to the suture. 
The aperture is short and broad, angulated at the shoulder, strong- 
ly excurved at the base of the columella, which is short and straight, 
with a strongly sinuous inner margin; the posterior sinus is broad, 
shallow and inconspicuous. The canal is very short and broad, not 
constricted, rounded at the end. Color, white. 
Length, 8"; breadth, 5°5"™; length of body-whorl, 6™™; length 
of aperture, 5™™ ; its breadth 2:20™,
