sulcatus, sulcis punctnratis ; albicans, castaneo pallide f'asciatiin 

 maculatus (f. 372, 373).— The variety f. 372 is a little swelled 

 at the middle and then suddenly contracted. The deep grooves 

 are crossed by lines of grow th. 



84. akcuatus, Brod. et Soiob. — C. C. cancellato similis, sed 

 lineis elevatis cinctus; flammis castaneis pictus (f. 384). — In- 

 stead of grooves, as in C. cancellatus, we have outstanding ridges 

 in this species, and the markings are zigzag. 



85. pateici'JS, Hind. — C. fulvus, sulcatus, infra medium con- 

 tractus ; spira elevata, mouilifera (f. 355). — Pale yellowish- 

 brown, sulcated, the spire beaded, the body-whorl bottle-shaped. 



80. sulcatus, Brug. — C. oblongus, straroineus, sulcatus, ad 

 anguluni undulatus, spira brevi (f. 30). — Differing from this 

 group in general form, it is nevertheless sharp-spired. The body 

 is sulcated, and a variety, C. cos/atus of Chem. ?, occurs with the 

 intermediate ridges granulated. 



87. STiCTicus, A. Adams.— C. acutus, sulcatus, fuscus, flammis 

 longitudinalibus maculiferis ornatus; spira minute crenulata 

 (f. 137). — Very acute at both ends, sulcated, darkly variegated 

 with downward spotted flashes. 



88. Sowerbyi, Reeve. — C. elongato-fusiformis, distanter sul- 

 catus, interstitiis planatis ; pallidus, flammis fulvis longitudinalibus 

 ])ictus ; infra medium contractus ; spira elevata, lateribus incurvis 

 (f. 379). — This is like C. acutangnlatw, but drawn out at both 

 ends. 



89. I'ltiEOELLENS, A. Ad. — C. fusiformis, minute sulcatus, pal- 

 lide fasciatim maculatus; spira elevata, marginibus acutis (f. 371). 

 — Delicately sculptured, and tapering at both ends. 



90. Oebignyi, Ardouin. — C. elongatus, angustatus, sulcatus, 

 interstitiis planis ; fulvus, castaneo fasciatim maculatus ; spira 

 elevata, nodulis moniliformibus crenulata (f. 368). — This atte- 

 nuated shell has a beaded spire, and flattened ribs between equi- 

 distant sulci. 



91. aculeiformis, Reeve. — C. attenuatus, costis rotundis 

 cinctus, spira monilifera (f. 370). — Like C. Orbignyi, but witk 

 rounded ribs between the sulci. 



92. insculptus, Kien. — C. attenuatus, fuscus, sulcatus, sulcis 

 striatis, interstitiis plains ; antice angustatus; spira elevata, moni- 

 lifera (f. 363). — I am inclined, with Reeve, to consider this as 

 a variety of C. Orbignyi.
