1. C. lucidum, Lowe. 
T. globoso-conoidea abbreviato-obesiuscula leeviuscula nitida solidi- 
uscula obsoletissime angulato-carinata vy. ecarinata subimperforata 
8. rima angustissima strictissima y. fere clausa; spira abbreviata, 
anfr, subtumido-convexis transverse ineequaliter substriatis, ali- 
quando indistincte creberrime hine inde transverse subtilissime 
striatis spiraliterque obsoletissime striolatis, ultimo majore latiore 
ventricoso, sutura valde impressa ; apertura spiram fere sequante.

a. polita; leevissima nitidissima plerumque major, striolis trans- 
versis ineequalibus exoletis, spiralibus nullis.— Prim. /. ¢. t. 6. 
f.40; Kiist. Mart. et Chemn. t. 13. ff. 26, 27. 
Long. 63-62, diam. 6-53 mill. ; apert. 3, spira 4 longa; anfr. 43-5. 
f. rustica; sericeo-nitens paulo plerumque minor, striolis trans- 
versis creberrimis subtilissimis distinctiusculis, spiralibus exoletis- 
simis obscuris paucis hinc inde obsoletissime punctulatim subde- 
cussata. 
Long. 5-6, diam. 54-53 mill. ; apert. 3, spira 3 longa; anfr. 43-5. 
Hab. in Madere declivibus sylvaticis dumosisve rupibusve hu- 
midis supra 1500 ped. ubique recens, necnon fossilis ad Canical, 
B vulg., arara. Neque in Portu S® neque in Desertis recens fossilisve 
occurrit ; exemplar enim unicum Porto-sanctanum, ex quo in Catal. 
Moll. Mad. J. c. C. lucidum “In Portu S® tantum fossile rariss.” 
dicitur, ad C. flavescens v. Neritoides procul dubio potius spectat. 
In Canariis etiam C. lucidum omnino deest. 
Extremely variable in colour : either dark olivaceous approach- 
ing to greenish black, chestnut, or coffee-brown of various in- 
tensity, with often a single light band on the last volution, or 
light-yellowish straw or olive horn-colour ; and either plain, or 
varied with dark bottle-green or light yellowish spiral lines or 
longitudinal stripes or strigz. 
It is also variable in the prominency of the angle of the last 
volution, which is, however, mostly altogether obsolete or evan- 
escent. | . 
Traces of a few faint, obsolete, irregular, spiral striee are 
usually discernible in 8 below the suture, on the last volution, 
towards the peristome, or in the neighbourhood of the umbilical 
cleft. Opercle reddish chestnut. 
wary, distinct from C. galeatus, and apparently of this species, has just 
been received by the Zoological Society of Amsterdam. Another new 
species has recently been described in the Proceedings of the Zoological 
Society of London (1860, pp. 211 & 250), from a bird in their Gardens, 
under the name C, bicarunculatus, making the fifth of the group.—P. L. S,
