Turbonilla (Pyrgiscus) elegantula Verrill. 
PI. 12, figs. 30, 31. 
Turbonilla elegantula Verrill, Trans. Conn. acad. arts and sci., vol. 5, p. 
538, 1882, = Turbonilla elegans Verrill, Amer. journ. sci., ser. 3, vol. 3, p. 
282, pi. 6, fig. 4, 1872 (not Turbonilla elegans Wood, 1842, nor Chemnitzia 
elegans Lycett, 1850, nor Chemnitzia elegans D'Orbigny, 1853). 
Shell broadly conic with light wax yellow surface and dark wax 
yellow spirally incised lines. Nuclear whorls very small, at least two, 
having their axis almost at right angles to that of the succeeding turns. 
Post-nuclear whorls well rounded, marked by strong, somewhat re- 
tractive axial ribs, of which there are about 18 upon the 2d, 3d, and 
4th; 20 upon the 5th, 6th, and 7th; and 22 upon the penultimate 
turn. In addition to these ribs the whorls are marked in the inter- 
costal spaces, which are a little wider than the ribs, by five, broad, 
deeply incised, equally strong and equally spaced spiral lines. These 
lines run up on the sides of the ribs, but do not cross them. Between 
the first of these lines and the summit of the whorls there are four very 
faint closely spaced spiral striations. Sutures well impressed. Pe-
