carinam angulata ; peristoma tenue, marginibus distantibus, colu- 
mellari leviter incrassato, ad insertionem breviter reflexo, perfora- 
tionem semiobtegente. 
Diam. maj. 10 millim., min. 9, alt. 5. 
The specimen here described may not represent the full 
dimensions attained by this species. It does not, however, 
appear to be the young state of any of the known forms. 
10. Helix (Coliolus) Canefriana. (Pl. XX. fig. 16.) 
Testa anguste umbilicata, depresse trochiformis, ad peripheriam 
carinata, supra rufo-fusea, infra pallidior vel olivaceo-fusca, epider- 
mide fugaci fibrata, fuscescente induta et laciniata ; spira concave 
conica, mediocriter elata, ad apicem mamillata; anfractus octo, 
lente accrescentes, tres superiores convexiusculi, spiraliter tenuis- 
sime striati, cterl minus convexi, striis obliquis validis arcuatis 
sculpti, in medio et ad suturam epidermide laciniato ornati, ultimus 
subacute carinatus, supra et infra equaliter convexus, sed inferne 
levior, striis tenuioribus sculptus, antice descendens ; apertura 
purpureo-fusca ; peristoma continuum, pallidum, leviter incras- 
satum, supra angulatum, haud reflexum, margine inferiore an- 
guste expanso et reflexo. 
Diam. maj. 183 millim., min. 163, alt. 11. 
This interesting species is very distinct from all the forms 
at present known from the island. It agrees with the type 
of the section Coliolus, C. arfakiensts, Canefri, in having the 
upper whorls spirally striate and the rest roughly striate ; 
the epidermis is fringed at the middle and base of the whorls, 
the apex is mamillated, and the form and character of the 
peristome are the same. The present species, named in 
remembrance of the late Dr. C. Tapparone Canefri, has a 
much less elevated spire and a more acute peripheral keel 
than C. arfakiensis. 
11. Pupina nasuta. (Pl. XX. fig. 18.) 
Testa ovata, obliqua, superne acuminata, rufescenti-cornea, sub- 
pellucida, polita; anfractus 5, convexi, sutura rufo-lineata sejuncti, 
penultimus magnus, paulo inflatus, ultimus pone oblique descen- 
dens ; apertura fere circularis, rufescens ; peristoma paulo incras- 
satum, pallido-rufo marginatum, antice leviter effusum, margine 
columellari supra producto, curvato, infra ad canalem prominente, 
nasuto; sinus posticus mediocris; fissura columellaris angustis- 
sima, obliqua, extra sinum amentiformem formans. 
Longit. 7 millim., diam. 43; apertura intus 23. 
In this species the anterior slit is situated considerably 
below the middle of the aperture.
