434 B. J. L. Gwppy — West Indian Tertiary Fossils. 



within. Pillar-lip smooth. Length about 25 mm. Breadth 

 about 15. Total length of last whorl, including canal, about 18 mm. 

 Very closely related to M. calcitrapa, Lam. (Eocene, Europe). It 

 is smoother and the whorls less angulate. These shells belong to 

 a small group of Murices which exhibits the connexion through 

 Trophon, Bapana, Latiaxis, etc., to Purpura. 31. coUatus would per- 

 haps be ranked by some conchologists as a Trophon, as has already 

 been done with M. calcitrapa. 



Typhis alatus, Sowerby. 



Journ. Geol. Soc. 1850, vol. vi. p. 48, pi. x. f, 4. 



A species almost as near to T. tubifer (Eocene, Europe) as Murex 

 collatus is to 31. calcitrapa. The living analogues of T. alatus are 

 T. pinnatus and T. Sowerhyi. 



Ancillaria pinguis, n. sp., PL XVI. Fig. 3. 



Ovate conic, spire elevated, acuminate. Suture usually visible 

 through the enamel which covers the spire, and accompanied at a 

 little distance by a keel, the ridge of which is threadlike. Aperture 

 suboval, elongate. Umbilicus deep, narrow, partly hidden by the 

 callosity of the inner lip. Columella callus strongly twisted. Central 

 portion of last whorl without enamel. 



Bears some resemblance to Anc. lamellata, Guppy. A near re- 

 lation is perhaps A. ruhiginosa, which has a spire of similar character. 



Cassis reclusa, n. sp. 



Ovate, ventricose, sulcated by about 18 narrow and shallow equi- 

 distant spiral grooves, the flattened intervening ridges being raised 

 into knobs by somewhat obscure longitudinal costse. Spire conic, 

 cancellated. Apex smooth, blunt. Columella expanded into a granose 

 callus ; canal short ; outer margin thickened and reflected, dentate. 



Very closely related to C. subulosa (a Bordeaux fossil). It is 

 chiefly to be distinguished by its larger spire and apex, generally 

 narrower and less ventricose figure, and somewhat stouter ornamen- 

 tation. Amongst recent West Indian species the nearest relation of C. 

 reclusa is C. granulata {'?=zcicatricosa, Meusch). 



Crepitacella cepula, Guppy. 

 Melanopsis cepula, Journ. Geol. Soc. 1866, vol. xsii. p. 580, pi. xxvi. f. 14. 

 Crepitacella cepula, Geol. Mag. Vol. IV. (1867), p. 500. 

 This shell is related to Cyllene pulchella, Adams. It is not im- 

 possible that some other fossils described as Melanopsis really 

 belong to the group Crepitacella. 



Monodonta hasilea, n. sp., PI. XVI. Fig. 2. 



Top-shaped, umbilicate. Apex smooth, sharp. Whorls about seven, 

 very strongly carinate, the stout keel on the angular ridge bearing a 

 row of rounded undulate tubercles, and having near the suture a less 

 distinctly marked keel, between which and the keel on the angle 

 there is a slight concavity, marked only by faint spiral ridges crossed 

 by lines of growth. Lower half of last whorl forming the base
