 unifasciata ; spira conoidea, apice obtuso, sutura profundiuscula, 

 rugose submarginata ; anfractibus 5, vix convexis, lente accrescen-

 apertura obliqua, rotundato-lunari, peristoraate expansiusculo,

 mellari expanso, reflexiusculo, umbilicum leviter occultante. 



Diam. major 20, minor 18, axis 13 mill. 



Habitat ad Sheoay-Gheen, Pegu. Detexit Capt. J. C. Haugbton. 



The umbilicus is wider in some specimens than in others, and 

 the angle above the periphery is variable, and occasionally more 

 pronounced. In dead specimens the livid violaceous colour of 

 the aperture and lip is changed into white, and the obscure 

 fuscous band at the periphery is scarcely to be detected. 



6. Streptaxis Andamanica, B. 



Testa rimato-umbilicata, depresse ovato-oblonga, oblique arcuatim 

 costulato-striata ; spira laterali, obtuse conoidea, sutura profunda ; 

 anfractibus 6, convexiusculis, prope suturam angulatis, primis re- 

 gularibus, antepenultimo gibbo, ad peripheriam non angulato, 

 duobus ultimis lateraliter longe divergentibus, ultimo lsevigato ; 

 apertura perobliqua, truncato-oblonga, lamella 1 parietali intrante, 

 peristomate tenui, acuto, expansiusculo, marginibus subparallelibus, 

 dextro antrorsum valde arcuato, sinistro reflexiusculo, margine 

 umbilicali compressiusculo. 



Long. 7, diam 4^ mill. 



Habitat in Insulis Andamanicis. 



A single specimen was found by Mr. Theobald in a dead 

 Cyclophorus received from the Andamans. The form is more 

 obliquely elongate and slender than that of S. Petiti, and is less 

 depressed in the conoid portion of the spire ; it has a deeper 

 suture, angulate at the outer edge, and the last of the regular 

 whorls is rounded, not angular, at the periphery on the left 

 side ; the edge of the umbilicus is angular, and the aperture is 

 narrower than in S. Petiti. 



7. Pupina Peguensis, B. 



Testa imperforata, subgloboso-ovata, laevigata, polita, pellucida, cor- 

 nea ; spira convexo-conica, apice acutiusculo, sutura calloso- 

 marginata ; anfractibus 4£, ultimo spiram superante, antice breviter 

 ascendente, ad basin foveato ; apertura subverticali, sursum spec- 

 tan te, circulari, angulo acuto superne adjecto, callo parietali su- 

 perne et lamella intrante munita ; columella profunde incisa, cana-
