fasciata, periomphalo lato albo. Spira depresso-conica, lateri- 
bus concavis, apice papillari, magis exserto, sutura profunda. 
Anfr. 5, convexi, ultimus magnus, ad peripheriam angulatus, an- 
gulo antice evanescente, subtus converus, juxta aperturam leniter 
descendens. Apertura fere rotunda, obliqua, lutescenti-albida, 
aliquantulum latior quam alta. Peristoma rectum, incrassato-ez- 
pansum, subcontinuum. Unmbilicus pervius. Operculum normale. 
Diam. maj. 46, min. 38, axis 25 mm. ; apert. cum perist. 23 mm. 
lata, 213 alta. 
Hab. haud procul a Bhamo, ad ripas fluminis Iravadi. 
Somewhat allied to C. pearsoni, Benson, and C. excellens, Pfr., 
but more depressed than either. It is distinguished from C. theo- 
baldianus, Bens., by its much smaller mouth and smoother surface. 
7. SPIRACULUM ANDERSONI, Sp. nov. 
Testa late umbilicata, depressa, discoidea, oblique striata, lineis ele- 
vatis minutis spiralibus superne et presertim juxta peripheriam, 
sed non circa umbilicum, confertissime decussata, albida, strigis 
castaneis fulguratis radiantibus picta. Spira plana, apice vel 
plano vel vir exsertiusculo, sutura profunda. Anfr. 44, teretes, 
ultimus versus aperturam longe descendens, 5—6 mill. pone peri- 
stoma tubulo suturali reverso parvo, arcuatim recurvato vel sub- 
recto et libero, 2-3 mm. longo muniius. Apertura diagonalis, 
rotunda; peristoma continuum, duplex, internum expansiusculum 
undique appressum, postice juxta anfractum penultimum profunde 
angulatim sinuatum, externum expansum, supra sinum dilatatum, 
juxta anfractum penultimum instar cuculli plani porrectum. 
Operc. persimile et Sp. hispidi, corneum, intus concavum, extus 
convecum, marginibus anfractuum, presertim externorum, lamel- 
latim liberis, apice planiusculo. 
Diam. maj. 153-17, min. 12-133, axis 5—6, apert. diam. intus 5 mm. 
Hab. ad Bhamo cum precedente. 
Distinguished from Sp. avanum, W. Blanf., by its more oblique 
mouth, differently shaped and more expanded peristome, by the 
horizontal cowl-shaped projection running forwards along the last 
whorl instead of being vertical, the greater distance of the sutural 
tube from the mouth, and the much more convex operculum. 
8. Herrx (TRACHIA) CATOSTOMA, Sp. nov. 
Testa late umbilicata, depressa, subdiscoidea, cornea, tenuis, striata. 
Spira depresso-conveaa, sutura leviter impressa. Anfr. 7, conveci, 
arcte convoluti, ultimus rotundatus, circa umbilicum subcompres- 
sus, antice abrupte deflerus, valde descendens, pone aperturam 
subconstrictus. Apertura fere horizontalis, truncato-ovata ; peri- 
stoma album, reflexum, antice et postice prope anfractum penulti- 
mum arcuatum, marginibus subdistanter convergentibus, callo tenui 
junctis ; umbilicus latissimus, pervius. 
Maj. diam. 16, min. 144, alt. 63 mm.
