 The Maue Natica. Shell umbilicated, globose, spire 

 a little exsertcd, suture impressed, whorls rouuded, 

 smooth, peculiarly obliquely plicately wrinkled next 

 the suture, aperture lunar-ovate, columella callous at 

 the upper part, with a columnar spiral callosity half 

 filling the umbilicus ; white, encircled with two in- 

 terrupted bands of rust-fawn blotches. 

 Eecluz, MS., Mus. Cuming. 

 Hab. Island of Mahe, Seychelles. 



A very characteristic species, encircled beneath the su- 

 ture with obliquely plicated wrinkles. 



Species 59. (Mus. Cuming.)

Forskal's Natica. Shell rather openly perspectively 

 umbilicated, globose, subventricose, spire shortly ex- 

 sertcd, whorls rounded, smooth, plicately striated 

 next the suture, aperture lunar-ovate, columella cal- 

 lously recurved at the upper part ; white, marked 

 throughout with longitudinal rust-fawu streaks, leav- 

 ing a white band in the centre.

Resembling the preceding species, but distinct in all its 

 detail of character. The suture of the spire is not simi- 

 larly impressed, the plicated striae are very different from 

 the wrinkles, and the umbilicus is not obscured by any 

 winding columnar callosity.

The bl:tteufly-wixg Natica. Shell largely umbili- 

 cated, subglobose, spire exserted, suture impressed, 

 whorls smooth, rounded, depressed and plicately 

 wrinkled at the upper part, last whorl much effused, 

 columella callous at the upper part, with a columnar 

 spii-al callosity entering the umbilicus; fawn-flesh 

 tinged, encircled with four white zones, fiUetcd with 

 distant square purple spots, callosity white.

 mud at ten fathoms) ; Cuming. 

 Well distinguished by its dark purple filleted zones and 



ell'used aperture.

 The lightning-marked Natica. Shell perspectively 

 umbilicated, globose, solid, spire short, somewhat 

 impressed, whorls rounded, rudely plicately striated 

 next the suture, aperture limar-ovate, columella 

 broadly callous at the upper part ; wlute, densely 

 longitudinally painted with irregular zigzag red- 

 brown streaks.

llah. Senegal. 



Of this species, from Senegal, varying more or less in 



its markings of dots, blotches, and zigzag flames, too many 



spm-ious species have been made.
