latter obconical, rectangular near the top, and flattened or concave above 
from the angle to the suture; sinus of lip above the angle of the whorls 
shallow and broad.” ‘The type is Surculites annosa Conrad, a New Jersey 
Eocene species. 
The type specimen used by Mr. Conrad in his description and figured 
on Plate 20, Fig. 9, of the volume cited above, is now in my hands, together 
with several other specimens of the same, and another much more slender 
species. ‘They differ but little generically trom Surewla proper as typified 
by S. nodifera Lam., except in the notch in the lip, and straighter anterior 
beak, which, from the evidence afforded by the specimens before me, does 
not appear to be bent or twisted to any extent. The form in both of these 
species is subequally biconical, the spire elevated and nearly or quite equal 
to the length below the angle of the principal volution. _ Below the angle 
the body volution is nearly straight obconical, giving a somewhat regularly 
tapering beak of moderate length and narrow canal. The upper surface 
of the volutions is nearly rectangular and the sinus scarcely marked; in 
fact, in most specimens the lines of growth indicating it are nearly direct, 
but below the angle the line is directed forward in a broad curved extension, 
occupying nearly the entire length of the aperture. The surface features 
are rather fine and subdued, consisting of spiral lines on the entire surface, 
and not very distinct lines of growth. Another of Conrad’s Eocene genera 
Cochlespira, cited by Tryon as a synonym of Pleurotoma, is so nearly like 
this one that it would be difficult to point out differences. The following 
are the only species yet referred to Surculites. .

Surculites annosa Conrad: Am. Jour. Conch., vol. 1, p. 213, Pl. xx, Fig. 9. 
Shell of comparatively large size, having been about 24 inches long, 
with a transverse diameter of the body whorl of 14 inches when entire; 
form subequally biconical, the length above and below the point of great- 
est diameter nearly equal; volutions five or more, sharply angular on the 
periphery, the upper surface flattened and nearly rectangular to the axis;
