Cancellaria bullata. Cati. testa ovato-conoided, tenui, 

 in/laid, ampliter 'profundi mibilicatd, spird exsertd, 

 turritd, mifractibm superne late impresso-canalietdaiis, 

 ad angidicm. rude oblique nodulatis, deinde convexis,

The bubble-like Cancellaria. Shell ovately conoid, 

 thill, inflated, largely deeply umbilicated, spire ex- 

 serted, turreted, whorls broadly irapressly channelled 

 roimd the upper part, rudely obliquely noduled at 

 the angle, then convex, obtusely wrinkle-ridged and 

 striated; dirty fulvous; aperture triangular-ovate, 

 sinuated at the base, colunicllar lip broadly reflected, 

 plaits two, small. 



SowERBi', Pro. Zool. Soc. 1832, p. 51. 



Hal. Gulf of Nicoya, Central America (from a muddy 

 bottom in twelve fathoms) ; Cuming. 

 Distinguished chiefly by its light inflated growth and 



large excavated umbilicus. 



Species 6. (Fig. a, 5, Mus. Cuming.) 



Cancellaria nodxjlifera. Can. testa ovato-venirkosd, 

 subjn/riformi, imperforatd, basi contorto-recurm, spird 

 turritd, anfraciibus superne excavato-canaliciilatis, 

 deinde convexis, longitudinaliter oblique costatis, liris 

 angustis nodulatis confertim spiraliter decussatis ; 

 luteo-fulvescente, fa^cid angustd albidd versus basin 

 cingulatd ; aperturd pyriformi-ovatd, plicis duabus, 

 mittutis. 



The noduled Cancellaria. Shell ovately ventricose, 

 somewhat pear-shaped, imperforated, twistedly re- 

 curved at the base, spire turreted, whorls excavately 

 channelled at the upper part, then convex, longitu- 

 dinally obliquely ribbed, closely spirally decussated 

 with narrow noduled ridges ; yellowish-brown, en- 

 circled with a naiTOw whitish band towards the base ; 

 aperture pyriformly ovate, plaits two, very small. 



Sowebby, Tankerville Catalogue, Appendix, p. 15. 

 Cancellaria imperialis, Michelin. 



Hab. Japan. 



The whorls of this species are rather broadly excavately 



channelled as in the preceding, but at the base they are 



closely convoluted into a twisted recurved extremity, 



leaving no trace of an umbilicus. 



Species 7. (Mus. Cuming.) 

 Cancellaria obesa. Can. testa ovatd, erassd, ponderosd, 

 imperforatd, spird breviusculd, acuminatd, anfractibus 

 convexis, superne declivibus, lavibus, obscuri spiralitei- 

 striatis versus apicem, minute reticulatis ; albidd, au- 

 rantio-fmco pallide nebulatd; aperturd oblougd, sub- 

 angustd, superrie sinuatd, fauce validissime liratd, pli- 

 cis duabus, crassissimis, prominentibiis. 

 The stout Cancellaria. Shell ovate, thick, ponder- 

 ous, imperforated, spire rather short, acuminated, 

 whorls convex, slanting at the upper part, smooth, 

 obscurely spirally striated towards the apex, minutely 

 reticulated ; whitish, faintly clouded with orange- 

 brown ; aperture oblong, rather narrow, sinuated at 

 the upper part, interior very strongly ridged, plaits 

 two, very thick, prominent. 

 SoWERBY, Pro. Zool. Soc. 1832, p. 52. 

 Hab. Gulf of Dulce, Central America (dredged from the 

 depth of fifteen fathoms) ; Cuming. 

 This fine species, of which two specimens in a young 

 state were brought to Mr. Cuming from Puerto Potrero, 

 is distinguished by its obtuse growth and prominently 

 developed columellar plaits, the surface of the last whorl 

 being smooth, whilst the earlier whorls are finely reticu- 

 lated. 



Species 8. (Fig. a, b, Mus. Cuming.) 

 Cancellaria Cassidiformis. Can. testd ovato-ventri- 

 cosd, pyriformi, imperforatd, spird brevi, acuminatd, 

 anfractibus spiraliter rugoso-striatis, ad suturam pro- 

 fundi anguste canaliculatis, deinde concavis et nodoso- 

 angulatis, nodis submuricatis ; aurantio-fulvd ; aper- 

 turd oblongo-ovatd, subampld, labro columeUari re- 

 curvo, late expamo, plicis duabus, acutis. 

 The Cassis-shaped Cancellaria. Shell ovately ven- 

 tricose, pear-shaped, imperforated, spire short, acu- 

 minated, whorls spirally wrinkle-ridged, deeply nar- 

 rowly channelled at the suture, then concave and 

 nodosely angled, nodules rather prickly ; orange- 

 fulvous; aperture oblong, rather large, columellar 

 lip recurved, widely spread, plaits two, sharp. 

 SowERBY, Pro. Zool. Soc. 1832, p. 53. 

 Hab. Panama (j'oung specimens dredged from a sandy 

 muddy bottom, at the depth of sixteen fathoms) ; 

 Curaing. 

 Allied to C nodulifera, but differing by its more bul- 

 bous inflated proportions, less twistedly recurved base, 

 and less exserted spire. 



November, 1856.
