The Chinese Natica. Shell with a uenrly covered uiii- 

 bUicus, seniiglobose, spire short, suture impressed, 

 narrowly cliauncUed, apex sharp, whorls plicately 

 striated round the upper part, then smooth, convex, 

 aperture semilunar, somewhat effused, umbilicus 

 large, half-filled with a broad callosity; white, re- 

 motely encircled with distant, somewhat square chest- 

 nut spots, covered with a thin epidermis. 



Lamarck, Anim. saus vert. vol. viii. p. 6i4. 



Hah. China and Philippine Islands. 



This species is chiefly distinguished by the distinct 



square-like character and distant arrangement of the spots. 



Species 83. (Mus. Cuming.) 



Natica Adansoni. Nat. tedd ampliter penpectm vui- 

 biUcatd, subglobosd, spird medlocri, apice acuta, aii-

Adanson's Natica. Shell largely perspectively umbili- 

 cated, subglobose, spire moderate, sharp at the apex, 

 whorls flattened and obliquely striated at the upper 

 part, then rounded, smooth, slightly attenuated to- 

 wards the base, aperture rather naiTOwly semilunar, 

 umbilicus with a slightly raised callosity ; flesh-white, 

 everywhere sprinkled with red dots, and encircled 

 with two obscure bands of blotches, callosity red. 



Le Fanel, Adanson. 



Natica Fanel, Recluz. 



Hab. East and west coasts of Africa. 



The name given to this species by the old French con- 

 chologist of Senegal cannot be strictly used in a Latin 

 form of nomenclature. It is always distinct both in form 

 and colouring from the allied species of Senegal, and in- 

 habits also Zanzibar. 



Species 8i. (Mus. Cuming.) 

 Natica Jckesii. Nat. testa umbilicatd, globo'so-neri- 

 toided, soUdissimd, crassd, spird mimitd, vix elevatd,

 viusculd, columelld late callosd, iimbilico perspectim ; 

 omnino nitente-ehurned. 



Jukes' Natica. Shell umbilicated, globosely neritoid, 

 very solid, thick, spire minute, scarcely elevated, 

 whorls convex, polished, aperture semilunar, rather 

 small, columella broadly callous, umbilicus perspec- 

 tive ; everywhere shining ivory-white. 

 Natica candidissima, Rccluz (not of Le GuiUou). 

 Iliib. North Australia ; Jukes. 



A very solid neritoid shell, of shining ivory-white sub- 

 stance, distinguished by a particularly small superficial 

 spire, and arched perspective umbilicus. 



Species 85. (Mus. Cuming.) 



Natica unimaculata. Nat. testd compresse umbilicatd, 

 suJipyriJ'ormi-ovatd, crassd, solidd, spird brevi, acumi-

 The one-spotted Natica. Shell compressly umbili- 

 cated, somewhat pyriformly ovate, thick, solid, spire 

 short, acuminated, whorls slanting at the upper part, 

 then convex, smooth, aperture lunar-ovate, columella 

 broadly callous at the upper part, umbilical callosity 

 moderate ; white, covered with a fulvous horny epi- 

 dermis, callosity stained with a purple spot. 

 Hub. Mnzatlan ; Lieut. Shipley. 



A solid shell, of a pyriformly ovate shape, whitish, co- 

 vered with a conspicuous fulvous epidermis. Its chief 

 peculiarity consists in there being a characteristic purple 

 stain on the umbiKcal callosity. 



Species 86. (Mus. Cuming.) 

 Natica Gallapagosa. Nai. testd ai/gnste arcnatiin um- 

 bilicatd, ovato-globosd, crassiusculd, spird brevitisculd,

 The Gallapagos Natica. Shell naiTowly arcuately 

 umbilicated, ovately globose, rather thick, spire rather 

 short, obtuse, whorls slanting at the upper part, then 

 flatly convex, smooth, or very finely obliquely stri- 

 ated, aperture ovate, columella very callous at the 

 upper part ; ash-lead, with a broad light orange band 

 next the suture, interior of the aperture brownish. 

 Kecluz, Pro. Zool. Soc. 1843, p. 213. 

 Hab. Albemarle Island, Gallapagos group (in coral sand);

 An obtusely ovate species, of a lead-ash colour, encir- 

 cled round the spire with a broad pale orange band.
