106 PALEONTOLOGY OF NEW JNRSEY. 
Formation and locality: In friable green marls of the Lower Marl Beds. 
at Holmdel, New Jersey. Collection at Rutgers College. 
Genus CITHARA Schum. 
CITHARA MULLICAENSIS, n. sp. 
Plate xm, Figs. 2-6. 
Shell moderately large and robust for its length, with a short, obtusely 
pointed spire and very large body whorl, which constitutes nearly the 
entire bulk of the shell; the spire, measuring from the swell of the body 
volution when looking upon the front of the shell, forming about two-fifths 
of the entire height; volutions four and a half to five in number, short, 
indistinctly marked and the sutures obscure ; the body whorl somewhat 
produced below, forming a short canal; aperture large, elliptical, pointed 
above and notched below; and about equaling one-half the length of the 
shell; surface of the shell marked with strong, longitudinal ribs, which are 
quite distant and number only about ten on the body whorl; the ribs are 
strong, sharply. elevated, with concave interspaces, and with fine longitu- 
dinal lines of growth marking the surfaces; and the whole crossed by ele- 
vated thread-like raised lines, distant and distinct, but most plainly marked 
on the ridges; on the internal casts, the most usual condition, the spire 
is more elevated and the form less robust, with more distinct sutures and 
the volutions more ventricose, while their surfaces are less strongly marked 
by the longitudinal ribs, and no spiral lines are visible; no evidence of 
markings can be detected on the columella, either on the shell or on the 
cast. The outer lip of the aperture appears to have been slightly thick- 
ened, but no evidence of internal striz exists. The features of the notch 
in the outer tip can not be ascertained. . 
I see no reason to question the generic relations of this shell, although 
some of the features are too obscure for positive description; those that 
are retained seem too well marked for doubt. The same remarks made 
under G. Crosswickensis in regard to generic references apply equally well 
to this species. 
Formation and locality: In the dark ferruginous layers at the base of the 
Lower Green Marls at Mullica Hill, New Jersey. State collection made
