 berculis maguis coronata; anfractibus paucis, latis (f. 560). — 

 The well-known map-coloured, large, coronated shell. 



347. tolipa, Linn. — C. C. geographo similis, sed medio ven- 

 tricosus, spira angustiore vix coronata ; lineis articulatis cinctus ; 

 flammis undatis (f. 551, 552). — The centre is ventricose, and 

 the spire narrower than in C. geographies, scarcely coronated ; it 

 is encircled with articulated lines.

 obliquus, augustior, medio inflatus ; spira elevata, angusta, tuber- 

 culis mediocribus corouata (f. 549). — Marked in the manner of C. 

 geographus ; it is more oblique, the spire narrower, more elevated, 

 and less largely coronated.

 angustior, spira laevigata; ca3ruleus, castaneo fasciatiin obscure

 lata; anfractibus latis, planulatis (f. 548). — Eesembling C. bullatus,

 cate fawn-tint and tessellated markings further distinguish this 

 elegant and extremely rare species.

 aurantio nebulosus, fusco irregulariter variegatus ; spira parva, 

 depressa; anfractibus paucis, canaliferis (f. 550). — Beautifully

 lide nebulosus (f. 546). — Froin its light fawn-colour, mistaken 

 by us formerly for the C. cervus.
