The pea-shaped Natica. Shell narrowly deeply umbili- 

 catecl, globose, rather solid, spire very small, whorls 

 obtusely produced round the upper part, then slightly 

 convex, aperture oblong-ovate, columella slightly cal-

Huh. Valparaiso ; Cuming. 



.V small pea-like shell, obtusely gibbous round the upper

The little ass Natica. Shell with a covered umbili- 

 cus, obliquely globose, depressed beneath, spire very 

 sliort, whorls convex, smooth, shining, faintly pli- 

 cately striated next the suture, aperture semilunar- 

 ovate, columella with a broad callosity covering the 

 umbilicus ; white, encircled with two rather broad 

 blue-blaek bands, with a minute series of dots in the 

 interstices. 



llnb. Australia. 



An interesting small species, in which the painting is 



iiut much unlike that of the Ci/prupa asettiis. 



Species 137. (Mus. Cuming.) 



Natica Traillii. Nat. ti-std MdjuM/i/if,;- i,„ihllicatd, co-

Tuaill's Natica. Shell largely umbilicated, eonoidly 

 globose, rather solid, spire small, whorls slanting 

 round the upper part, peculiarly flatly excavated be- 

 neath, aperture ovate, columella with a broad callo- 

 sity nearly covering the umbilicus ; whitish, painted 

 longitudinally throughout with waved irregular red- 

 brown lines, callosity red-brown. 



Hah. Malacca. 



A characteristic solid species, curiously excavated and 

 obtusely angled at the base, painted throughout with irre- 

 gularly waved red-brown lines. 



Species 13S. (Mus. Cuming.) 

 Natica venustula. Nat. te.'iid obtecte umbiUcaid, semi-

 The phettily-marked Natica. Shell with a covered 

 umbilicus, semiglobose, spire obtusely conoid, whorls 

 convex, smooth, shining, aperture lunar-ovate, colu- 

 I mella broadly callous, tilling the umbilicus; white, 

 j opake next the suture, then marked with zigzag red- 

 [ brown lines.

 Hab. ? 



The chief peculiarity of this little species consists in its 

 opake-vvhite zone round the upper portion of the whorls, 

 from which the light red-brown zigzag lines suddenly de- 

 pend. 



Species 130. (Mus. Cuming.) 

 Natica suffusa. Nat. testd oblongo-ovatd, soUdd, spird
