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. intermedia of Sowerby from the 

 Haitian miocene. It bears a resemblance to F. jilamentosa, 

 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. tarbellia?ia Grat. 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. 



Phos 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. Columella 

 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.
