410 R. J. L. Guppy — West Indian Tertiary Fossils. 



Mangelia micropleura, PL XYIII. Fig. 6. 



Subfusiform, longitudinally ribbed, the ribs crossed by numerous 

 strise, of which a prominent one forms an angle on the upper part of 

 the whorls; last whorl longer than the spire; aperture rather narrow, 

 lanceolate, with a sinus on the posterior part of the thickened peris- 

 tome. 



Pliocene, Trinidad. Allied to M. pulcJiella. The ribs vary con- 

 siderably as to size and distance apart. 



Purpura miocenica, n. sp., PL XVI. f. 9. 



Subpyriform, rather ventricose above, rimate, narrowed and pro- 

 duced anteriorly, adorned with longitudinal ribs (about 10 to the 

 whorl), which are crossed by coarse rugose high narrow spiral ridges 

 or threads. Whorls about «ix, apex acuminate. Pillar-lip smooth, 

 reflected over the shallow umbilical fissure. Canal produced. Outer 

 lip sharply dentate by the spiral ridges. Length about 22, breadth 

 about 15 mm. 



The outer layer of the shell is usually removed, and where this is 

 the case, each spiral rib appears to be double ; but when the outer 

 surface is preserved, the somewhat foliated or echinated rugosities of 

 these ribs are very obvious. 



This is a CoralliopMla, and is related to the P. galea (Chemn.) of 

 D'Orbignj', of which the name ought probably to be P. plicata, the 

 appellation galea being the rightful property of a closely allied East 

 Indian shell. Another form with which the Jamaican fossil may be 

 compared is P. squamulosa, Eeeve. 



Fasciolaria textilis, n. sp., PI. XVI. Fig. 5. 



Elongate, fusiform, closely cancellated by num.erous spiral ridges 

 from one to two mm. distant, between which are (especially anteriorly'-) 

 one, two, or three finer theadlike ribs ; and by numerous closer and 

 smaller longitudinal lines. Whorls six, the first two of which are 

 smooth, the apex deciduous and usually wanting, the last more than 

 two-thirds of the shell, rather ventricose above the middle, jDroduced 

 and rather attenuated anteriorly ; bearing on the upper half 5-7 

 elongate rounded tubercular prominences. 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 re- 

 semblance to F. filamentosa, 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 elongate. 

 It is very different from F. Tarbelliana, Grat., which occurs at Cumana 

 in Yenezuela, as well as in Chili and Europe. F. textilis exhibits 

 the close alliance of the genus to Turbinellus. 



Phos erectus, n. sp., PL XVI. Fig. 1. 

 Solid, turreted, conic-cylindric, finely striated longitudinally, and 

 adorned with stout longitudinal variciform ridges, which are highest
