//„/;. -i 



This has all the appearance of an Arctic species, thinner 

 in substance and rounder than N. Grmtlaiidica, with a 

 shorter spire.

Hab. North Seas. 



Allied to N. Grmilandica, but distinguished from that 

 species by the spire being less exserted. 



Species 121. (Mus. Cuming.) 

 Natica genuanus. Nat. testd imperforatd, subr/lobosd, 

 spird breuiusculd, anfractibus convexis, Icevibus, aper-

 The gartered Natica. Shell imperforated, subglobosc, 

 spire rather short, whorls convex, smooth, aperture 

 semilunar, columella with a very large reflected cal- 

 losity ; yellowish-white, encircled with three distant, 



narrow, red - brown filleted bands, the interstices 

 filled with red-brown dots, with a row of flames next 

 the suture. 

 Hab. South Africa. 



A very characteristic solid species, in which the seat of 

 the umbUicus is entirely covered with callous matter, and 

 the painting is pecuhar. Eound the upper part of the 

 whorls is a row of red-brown flames as in N. coUaris, the 

 remainder of the shell being painted with close-set dots of 

 the same colom-, inteiTupted at rather distant intervals 

 with three filleted bands.

 The girl Natica. Shell narrowly deeply umbilicated, 

 oblong-ovate, thick, solid, spii-e rather short, conoid,

 rather small, columella with a thick broad callosity 

 at the upper part ; ivory-white, covered with a thin
