1866.] GUPPY WEST-INDIAN TEETIAEIES. 579 



D^Orbigny has published figures of a number of fossils from Cuba, 

 which he identifies, for the most part, with recent species* ; but as 

 they are all casts, it is difficult to place reliance on the determina- 

 tions. Two of his species I have recognized in the Miocene beds of 

 Jamaica, San Domingo, and Trinidad. One of these is the Natica 

 jjJiasianelloides, and the other is Tellina Sagrce, which seems to me 

 identical with T. hiplicata of Conrad. 



Beyond some general notices scattered through various works, I 

 believe but little more is known of the geology and palaeontology of 

 the West Indies than I have indicated. The present summary, 

 though not, perhaps, of much interest as far as it relates to the 

 later Tertiaries, will be of service to future investigators of West- 

 Indian geology f. 



II. Descriptions of the New Species. 



1. KiSSA SOLIDULA, SpCC. UOV. 



Shell turreted, thick, costated by stout distant rounded ribs, which 

 are almost developed into tubercles on the angle of the whorls, and 

 are cancellated by numerous fine and close spiral costeUse, of which 

 there are usually two finer in the interval between two larger ones ; 

 spire conical, sharp ; whorls 8, somewhat angulate above, the last 

 much larger, forming two-thirds of the length of the shell ; outer 

 lip dentate, thickened externally, forming a varix ; columeUar margin 

 with a narrow callus; columella strongly twisted; canal short, 

 abruptly reflected. 



This form is related to N. prismatiea, Brocchi; but there are con- 

 siderable differences, among which are the relative narrowness of 

 the present shell and its sharper spire. 



Locality. — Cumana, Upper Miocene. 



2. Ancillaria lamellata, spec. nov. 



Shell ovate- conic ; spire elevated, acuminate, spirally striated ; last 

 whorl rather ventricose, spirally striate above ; aperture suboval, 

 elongate ; columellar margin rather strongly folded and bearing a 

 lamellar parietal tooth or plait, which extends into the interior, ob- 

 structing the posterior part of the aperture.
