Avith a spiral keel at the upper part of the body-whorl. — Hab, 

 Philippines, &c. 



5. Keeyii, pi. V. f. 48, Philippi ; variaLilis, Reeve non 

 Grat. — Quam petholatus magis depressa, apertura amplior, 

 columella alba. — I have considerable hesitation in admitting 

 this as a species. Some of the varieties of petholatus come 

 so near that it is not always easy to distinguish them. 

 Grateloup having given the name Turbo variabilis to a fossil 

 species in 1828, Philippi has changed the name of Eeeve's 

 variabilis to Reevii. — Hab. Philippines, &c. 



6. SMAKAGDUS, pi. vi. f. 58, Martyn, Univ. Conch. ; 

 Gmelin, Syst. Nat. p. 3595. — Testa subglobosa, imperforata, 

 cseruleo-viridis, epidermide olivacea induta ; anfractus rotun- 

 dati ; apertura cireularis, peristoma simplex ; columella 

 latiuscula, concava. Operculum extus convexum, minutis- 

 sime granulatum, viridi. — A species of very simple form and 

 character, in external appearance much like a Helix. — Hab. 

 New Zealand. 



7. MAGNiFicus, pi. vi. f. 59, Jonas, Zeitsch. Mai. 1844, 

 p. 167. — Testa ventricoso-ovata, imperforata, viridula, fusco 

 nigroque variegata et maculata ; anfr. convexi, obscure sub- 

 tiiissime striati ; spira acuta; anfr. ultimus superne leviter 

 depressus deinde inflatus; apertura subcirculari ; columella 

 mediocriter lata leviter depressa. — A fine characteristic 

 species, quite unlike any other. It is rare in collections. — 

 Hab. Bay of Sechura, Peru. 



8. JouRDANi, pi. vi. f. 62, and vii. 71, Kiener, Eevue 

 Zool. Soc. Cuv., 1839, p. 324. — Testa maxima, ovato-conica, 

 imperforata, rubescente-fusca ; spira acutiuscula, mediocriter 

 elevata ; anfractus convexi, priores spiraliter costati ; anfr. 

 ultimus ventricosus, interdum obscure spiraliter sulcatus, 

 plerumque longitudinaliter leviter corrugatus ; apertura 

 ampla, subcircularis ; labrum tenue ; columella convexa, 

 tenuiter effusa, superne callosa, inferne angulata. — The largest 

 species of the genus, yet one of considerable rarity. One 

 specimen in the British Museum, about six inches long, has 

 the upper whorls prominently ribbed, and the last whorl 

 encircled with about a dozen broad scarcely raised ribs ; but 

 a much larger specimen, about twelve inches long, recently 

 in my possession, presented scarcely any trace of ribs on the 

 last whorl. — Hab. New Holland,
