Gibbula Dupontiana— N. S., PL XVII, Fig. 8. 



T. parva, trochiformis, pallida, transversaliter ma cutis irregulari- 

 bus ftiscis notata ; anfractibus costulis senis spiralibus, crassis 

 circumdatis,prope suturam angustioribus, transversaliter lineis subtilis- 

 simis obliquis ornatis ; ultimo anfractu ad peripheriam angulato, ad 

 basin applanato, profunde umbilicato ; aperturd sub- quadr angular i, 

 labro ad marginem acuto, intus sub-incrassato ; labio tenui, simplici, 

 leviter arcuato. 



Alt. 7 Mil. — Diam. maj. 6 Mil. 



Common on sea-weed at low water, S. Prov. Ceylon. 



This species is named after M. Dupont, of Mauritius, whose in- 

 defatigable zeal has so greatly increased our knowledge of the interesting 

 fauna of that Island. The nearest shell, I know of, to the above is 

 one described by Reeve as Ziziphinus vexillum (Gr. Nevill). 



Gibbula Blanfordiana— N. S., PL XVII, Fig. 9. 



T.parva, turbinata,depresso-globulosa, solida, alba, r abide variegata 

 et niarmorata ; spira ad apicem sub-obtusa ; anfractibus quinis, postice 

 sensim angustioribus, ad medium sub-angulatis, spiraliter costulatis : 

 costulis senis, crassiusculis tenuioribus altcrnanlibus ; ultimo anfractu 

 ad peripheriam rotundato ; basi convexiuscula, umb-ilicata : umbilico 

 callositate albida, paulo incrassata, circumscripto ; apertura mb-rotwi- 

 data, labro crass iusculo, intus striato, ad marginem cleganter crenulato, 

 postice paulo defiexo ; labio prope recto, oblique decurrente, led, ad 

 medium paidulum incrassato. 



Alt. 5h Mil. — Diam. maj. 6£ Mil. 



Not uncommon ; — S. Prov. Ceylon ; found on sea-weed at low water. 



A somewhat allied species to the above was described by Deshayes 

 in his work on the shells of Bourbon, as Turbo (!) f lifer, the differ- 

 ences in the umbilicus, the columellar margin, &c. t however, distin- 

 guish it at the first glance. I have, also seen this species from Arakan, 

 in Mr. H. F. Blanford's fine collection ; like the following, it probably 

 has some considerable range in these seas. (Gr. Nevill). 



Gibbula Stoliczkana— N. s., PL XVII, Figs. 2-3. 



T. conoidea, parva, solidula, olivacea seu rufescens, macidis trans- 

 versalibus pallidis notata, aut minute variegata, epidermide falvescente 

 induia ; anfractibus senis, sub-planis, suturd impressd sejunctis, spira-
