whoils, itartcd by u liiu'ur suture. The colouratidii of the wlioils 

 is fairly uniforiu. w ith no indication of markings as in the previous 

 species. The shell is hhu li lounded anteriorly. Aperture pyriforrn. 

 Labruin thin, .simple. Lal)iaui moderately thick on the Vjody. 



Dhnr/is/o/is of ti/pc. — Len<ith, 1.75; breadth, G mm. 



LovaUfi/. — Kileunda, in shell sand. 



Ohservntion. — This is the smallest of our Victorian species, and 

 is immediately separable by its squat form, dome-shaped apex, and 

 uniform colouration. Its nearest ally is L. joshuana, GatlifF and 

 Gabriel, which is here refigured for comparison. 



Type in Mr. C. J. Gabriel's collection. 



Lkiostraca STYLiFORMis, sp. uov. (PI. XIV., Figs. 4 and 5). 



Shell minute, acuminate, smooth, glassy. Whorls nine, through 

 Avhich the axial pillar may be plainly seen. Whorls ai'e slightly 

 •convex; suture fairly distinct in consecpience of the slight rounding 

 of the whorls. Tlie generic characteristic is indicated in the later 

 whorls by fairly distinct, but irregular orange-tinted markings, 

 more numerous and more pronounced on the body-whorl. Aperture 

 somewhat pyriform, outer-lip thin and roundly prominent at the 

 periphery. Inner lip slightly reflected. 



Dimensions of type. — Length, 2.5; breadth, 8 mm. 



Locality. — Dredged off Wilson's Promontory. 



Observation. — A most delicate and curious little shell; its distinct 

 acuminate form .serving to distinguish from the Victorian members 

 of the genus. 



Type in Mr. C. J. Gabriel's collection. 



■Cyclostrema kilcundak, sp. nov. (PI. XV., Figs. 8, 9 and 10). 



Shell very minute, white, hyaline, of four whorls including the 

 smooth globular protoconch. Discoidal, spire sunken, widely um- 

 bilicated. Ornamented with transverse riblets, aboiit twenty-seven 

 •on the body-whorl, they are irregularly spaced, becoming more 

 •crowded towards the mouth, the intervening spaces are traversed by 

 very fine encircling incised lines. Mouth circulai-.
