on the axis of C. Salleana and Hjalmarsoni. It is curious 

 that no species peculiar to Jamaica has a similar character of 

 axis. 



Macroceramus Swifti, nov. sp. 



T. imperforata, cylindraceo-turrita, confertim striata, punctis numero- 

 sis et strigis obliquis fusco-corneis variegata; spira ovato-conica, apice 

 obtusula, pallide cornea; anf. ll£ vix convexiusculi, ultimus rotundatus, 

 infra medium obsolete fllo-carinatus ; apertura diagonalis, rotundato-luna- 

 rio, perist. albido, expansiusculo, inerassato, margine dextro arcuato, 

 columellari dilatato. 



Shell imperforate, cylindrically turreted, crowdedly seriated, variegated 

 with oblique dark horn colored stripes and numerous spots ; spire ovate- 

 conic, apex rather obtuse, pale horn-colored; whorls ll£ scarcely convex, 

 the last rounded, obsoletely carinated below the middle ; aperture diag- 

 onal, roundly lunate ; peristome whitish, rather expanded, thickened, the 

 right margin arcuate, columellar margin dilated. 



Long. 11, lat. 4 mill. ; ap. 3 mill, long, 2 lat. 



Habitat. Turks Island, also Inagua, Bahamas. 



Remarks. This species is allied to M. Hermanni, Pfr., of 

 Haiti, but is less distinctly costulated, the suture not crenu- 

 lated and has thicker peristome. 



I dedicate the species to the late Mr. Eobert Swift, from 

 whom I originally received specimens. 



Macroceramus Klatteanus, nov. sp. 



T. rimata, oblongo-turrita, solidula, oblique costulata, albida, strigis 

 interruptis et maculis castaneis ornata; spira elongata, apice albido; 

 sutura subcrenulata ; anfr. 10 convexiusculi, ultimus rotundatus, basi ad 

 aperturam compressus, infra peripheriam fascia 1 nigricante, interrupta, 

 notatus ; apertura diagonalis, subcircularis ; perist. albo, obtuso, margin- 

 ibus approximatis, dextro subarcuato, columellari subdilatato. 



Shell rimate, oblong-turreted, rather solid, obliquely ribbed, whitish 

 with chestnut colored interrupted stripes and spots ; spire elongate, apex 

 whitish ; suture subcrenulated ; whorls ten, rather convex, the last rounded, 

 compressed at the base near the aperture, one interrupted dark band 

 below the periphery; aperture diagonal, subcircular; perist. white, ob-
