156 Descriptions of Two New Species of Cylindrella. 1 



Habitat. — Endeavour Moreland, in the parish of Hanover, 

 Jamaica. 



Cylindrella aniethystina. 



Plate V. Figs. 3, 4. 



T. rimata, truncata, subcylindrica, elongata, sericina, ametbystina, 

 infra suturam saturation, striis obliquis sculpta ; sutura impressa, margi- 

 nata. ; anfr. superst. 10, subequalibus, subplanis, ultimo adnato ; apertura 

 subcirculari ; peristoraate luteo-fulvo, expanso, breviter refiexo. 



Shell of the C. rosea group, almost cylindrical, elongate ; 

 deep plum color, with a lighter band of the same on the lower 

 half of the whorls ; with rather coarse oblique strise, yet giving 

 the shell a silky lustre ; spire with outlines convex, but very 

 little so about the third, or fourth and fifth whorls ; apex trun- 

 cate, with the loss of — whorls ; whorls remaining 10, scarcely 

 convex, margined or shouldered on the lower side, with a 

 moderately impressed suture ; lip appressed to the last whorl, 

 small, expanding more on the right than left side, on the upper 

 part oblique and angular ; of a dingy light (almost white) 

 plum color ; thickened and reflected as in other species of this 

 group. 



Length, about 0.52 inch ; diameter, 0.23 inch. 



Habitat — Endeavour Moreland, Hanover, Jamaica. 



Of this shell, a variety occurs of a waxy color, which I de- 

 signate C. amethystina var. cerina. 



Cylindrella Baquteana. 



This Jamaica species was described by me in my Cont. to 

 Conch., pt. I., 1853, as C. Adamsiana. 



That specific name being pre-occupied, I substitute the above. 



Note. — I have recently discovered in Jamaica a species of Leptinaria, which 

 Mr. Shuttleworth pronounces to be new ; it differs, lie remarks, from his L. An til- 

 larum in size, and more prominent and distant 6tria?.
