■WEPT — JAMAICAN TERTIARY FOSSILS. SI 
apex deciduous and usually wanting, the last more than 
two-thirds of the shell, rather ventricose above the middle, 
produced and rather attenuated anteriorly ; bearing on 
the upper half 5 — 7 elongate rounded tubercular pro- 
minences. Columella margin with three strong tooth-like 
plaits. — Interior of peristome smooth.. Length nearly 70 
mm, breadth 30. 
The cancellation gives to the surface an appearance like 
that of coarse cloth or bagging. This species should be 
compared with the F s intermedia of Sowerby from the 
Haitian miocene. It bears a resemblance to F. filament osa, 
but is shorter, stouter, and less angular in all its features 
except only the tubercles, which are disposed in similar 
fashion, but are perhaps somewhat larger and more elon- 
gate. It is very different from F. tarlelliana Gr.at. which 
occurs at Cumana in Venezuela, as well as in Chili and Eu- 
rope. F. textilis exhibits the close alliance of the genus to 
Turbinellus « 
JPJios erectus n. sp, PI. I, f. 1. 
Solid, turreted, conic-cylindric, finely striated longitudi- 
nally and adorned with stout longitudinal variciform ridges 
which are highest on the angle of the whorls, become obso- 
lete at the shallow suture and are twisted at the base : 
coarse spiral threads cross the longitudinal grooves and 
ridges, rising on the latter into low scarcely noticeable 
tubercles. Whorls about 9, increasing very gradually, 
slightly angulated, the last forming more than one half the 
length of the shell. Aperture rather narrow. OolumeHa 
twisted bearing one spiral plait. Outer lip simple, having 
12 — 15 entering grooves, and furnished with a small sinus 
near the anterior canal; joined posteriorly with the body* 
whorl by a callus. Length about 21, breadth about 10 
mm-
