bilicus deep, narrow, partly hidden by the callosit3 T of the 

 inner lip. Columella callus strongly twisted — central por- 

 tion of last whorl without enamel. 



Bears some resemblance to Anc. lamellata Guppy. A 

 near relation is perhaps A. rubiginosa, which has a spire of 

 similar character. 



Ancillaria glandiformis Lam. 

 I think it possible that some of the examples of Anci- 

 llaria from Jamaica belong to this species, as I noticed in 

 the Geological Magazine, vol. iv, p. 498. 



Cassis reclusa n. sp. 



Ovate, ventricose, sulcated by about 18 narrow and 

 shallow equidistant spiral grooves, the flattened interven- 

 ing 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 ornamentation. Amongst recent 

 Westindian species the nearest relation of C. reclusa is 

 C. granulata (?=ciacatricosa Meusch.) 



Crepitacella cepula Guppy 



Melanopsis cepula, Journ. Soc, vol. xxii, p. 580, pi. 

 xxvi, f. 14. 



Crepitacella cepula, Geol. Magazine, vol. iv. (1867) p. 

 500. 



This shell is related to Cyllene pulchella Adams. It is 

 not impossible that some other fossils described as Melanop- 

 sis really belong to the group Crepitacella.
