112 NERITA. 



39. ANNULATA, f. 75, Reevc. — Scarcely distinct from N. 

 chamceleon. A little more flattened in the ribs, with the 

 white bands more distinct than the flames. 



40. FULGTJRANS, f. 32, Omelin. — Quam N. chamceleon magis 

 regulariter costata, costis concinne crenatis, elevatis, inter- 

 stitiis angvistis, colore pallido, nigro angulatim flammulato et 

 tessellato. — The ribs are neatly crenulated, rounded, and 

 distinct, with very narrow interstices, mottled in zigzag 

 flames of black ; mouth smoother than in N. chamcele07i. 



41. ALBiciLLA, f. 26, 27, 28, 113, Linnceus. — Ovato-sub- 

 trigona, solida, versus spiram angustissima (ultimo anfractu 

 magno), alba, grisea, vel aurantia, leviter transversim sul- 

 cata, nigro dense fasciatim variegata, aut rosea aurantio 

 maculata. Apertura magna, labio externo superne extenso 

 et elevato ; area columellari omnino verrucosa, margine acute 

 dentato. — N. marmorata^ Reeve, cannot be rightly dis- 

 tinguished from the well-known black-mottled shell. The 

 warts on the columellar area vary with the thickness of the 

 enamel. I take N. sanguinoleyita, Menke (B. M.), to be a 

 variety of pink colour mottled in two bands with orange. 



42. PATULA, f. 23, Recluz. — Quam N. alhicilla tenuior ; 

 apertura Iseviori, fere edentula. — In general form resembling 

 the preceding, but differing in its lighter and smoother 

 structure. 



43. YoLDii, f. 70, Recluz. — Quam N. patida brevior, 

 apertura baud tantum expansa, costis subobsoletis. — Another 

 dark-mottled species of similar form, but rounder. 



44. Beaniana, f. 50, Recluz. — Subovata, depressa, an- 

 gusta, roseo et griseo fasciata, fasciis griseis nigro-maculatis ; 

 spira parva subplanata, apertura expansa, area columellari 

 granulata, nigro unimaculata. — -Two different shells are given 

 under this name in Reeve. The one we have not figured is 

 certainly too near to be distinguished from N. Yoldii. 



45. achatina, f. 61, Reeve. — Ovato-globosa nigra, inter 

 liras planatas sulcata ; spira obtuse exserta, anfractibus 

 rotundis ; apertura ovata, area dolumellari declivi, obsolete 

 granulata, margine interne nigro reticulato et valide den- 

 tato, labio externo intus crenulato, superne dentato. — This 

 species is sculptured by narrow grooves between broad and
