310. planorbis, Born. — C. quam C. senator magis angulatus, 

 castaneo bifasciatus ; spira planata, nigro maculata ; anfractibus 

 earinatis (f. 491). — The dark-chestnut bands and the black-spotted 

 flattened spire sufficiently distinguish this from the preceding. 



311. vitulinus, Brug. — C. C. senatori similis, sed rubro-ni- 

 grescenfe fasciatus et variegatus, albo bifasciatus; spira plana, ma- 

 culata (f. 223, 224). — Known from C. senator by the greater 

 richness and depth of colour and markings, and the comparative 

 flatness of the spire. 



312. pulchelIjUS, Swains. — C. quam C. senator magis angus- 

 tatus, medio subcontracts, transverse punctato-lineatus, albo bi- 

 fasciatus; fasciis maculis interrupts; spira depressa, canaliculate, 

 maculata (f. 220). — I do not think, with Mr. Eeeve, that this is 

 only a bad state of C. ductus. 



313. cinotus, Swains. — 0. oblongus, roseus, granulatim li- 

 ratus, fusco late bifasciatus, prope angulum rubescens ; spira brevi, 

 anfractibus earinatis (f. 231). — The roseate hue of this, and the 

 depressed spire, distinguish it to the eye from C. senator. 



314. connectens, A. Ad. — C. C. cincto similis, sed angustior, 

 infra attenuatus, roseus, castaneo non fasciatus (f. 230). — This is 

 very likely to prove a variety of C. cinctus. 



315. LiNEATUs, CJiemn. — C. forma C. senatori similis, sed albus, 

 fusco fasciatus et variegatus, transverse striatus et lineatus (f. 218, 

 219). — Marked by transverse lines. The light, strongly granu- 

 lated var. f. 218 is the C. lacinulatus of Kiener. 



316. raphanus, Brug. — C. oblongus, leviter striatus, longitu- 

 dinaliter flammis aurantiis medio interrupts pictus ; supra subven- 

 tricosus, medio contractus ; spira subcarinata, striata, maculosa 

 (f. 494). 



317. carinatus, Sioains. — C. elongatus, leviter striatus, casta- 

 neo fasciatus et lineatus, prope angulum et medio albifasciatus ; 

 spira convexa; anfractibus sulcatis depressis et earinatis (f. 495). 



318. consors, Sowb. — C. oblongo-turbinatus, luteus, aurantio 

 fasciatus, supra inflatus, medio subcontractus, infra subattenuatus ; 

 spira elevata ; anfractibus sulcatis, canaliferis (f. 492). — Broad- 

 headed, yellow, with orange bands, a little contracted in the 

 centre. 



319. anceps, A. Ad. — C. quam C. consors magis attenuatus, 

 transverse punctatim lineatus, castaneo fasciis interrupts varie*
