R. J. L. Giippy — West Indian Tertiary Fossils. 407 



Closely akin to N. Lamar clciana, from which it is distinguished 

 by its naiTi-ower mouth. It is almost as near to N. papilla (Africa), 

 but it is less elongate in its proportions. 



Bulla Vendryesiana, n. sp. PL XVI. Fig. 6. 



Rimate, rather cylindrical-ovate, solid, smoth. Spire deeply sunk. 

 Aperture longer than the shell, dilated anteriorly. Inner lip covered 

 with a callus which is everted over the narrow umbilicus, and 

 extends backward to the canal separating the body-whorl from the 

 sharp outer lip. Length about 15, breadth about 9 mm. 



Allied to B. striata, Brug., particularly to that form called B. 

 maculosa, Mart. The surface of the fossil is not well preserved, and. 

 does not admit of an exact description of its characters. £. Vendryes- 

 iana is rather more cylindrical in shape than B. striata, and from 

 JJ. macidosa, to which it is nearer in figure, it is distinguished by its 

 greater solidity and its thicker and more everted columella callus. 



Tornatina coixlacryma, Guppy. 



Geological Magazine, 1867, Vol. IV. p. 500. 



Tornatella textilis, n. sp. PI. XVII. Fig. 4. 



Oval-oblong, solid, a little ventricose, closely cancellated by 



numerous spiral riblets and finer longitudinal threads most distinct 



in the spiral grooves. Spire short, conic. Whorls about 7. Aperture 



elongate, narrow, dilated anteriorly into a canal. Columella twisted, 



bearing a single stout fold. Outer lip sharp, finely dentated by the 



spiral riblets. Length 17, breadth 9 mm. 



In shape this shell approaches T. fasciata. It is of more solid 

 structure, its spire is somewhat shorter, and it is at once distinguished 

 by its cancellated surface. 



Cylichna ovum-lacerti, PL XVIII. Fig. 22. 



Shell small, cylindrical- subovate, minutely striate transversely ; 

 spire small, sunken ; aperture as long as the shell, dilated anteriorly ; 

 outer lip straight, blunt ; columella callus with a strong tortuous fold. 



Lower Miocene, Trinidad. 



Turhonilla turris. Orb., PL XVIII. Fig. 15. 



Chemnitzia turris, Orb., Moll, de Cuba, pi. xvi. f. 10-24. 



Other forms of this species are distinguished specifically by 

 D'Orbigny as C. pulchella, C. ornata, and C. modesta. 



These and other varieties are common in the Matura Beds, 

 Trinidad. 



Aclis helecteroides, PL XVIII. Fig. 11. 



Shell turreted, cylindric, many-whorled, shining, whorls slowly 

 increasing, impressed with a deep groove below the suture, which is 

 equally deep, forming a spiral thread ; aperture sub-circular, colu- 

 mella slightly reflexed, peristome simple. 



Pliocene, Trinidad. It resembles a Proto, but the columella pre- 

 vents its reference to that genus. I refer it to the genus Aclis 

 provisionally only, as I think it will be found to be the type of an 

 undescribed genus.
