Victorian Marine Mollusca. 83 



Columbella franklinensis, sp. nov. (PI. XVIII., y\<;. 3). 



Shell suiall, suioolli, acuminate, of six whorls; the body 

 whorl is inflated, and is rather more than half the lenjjth of 

 the shell. Whorls convex, suture well defined. Fine ascendinjj: 

 striae encircle the base, and cease at the columella ; base some- 

 what restricted, with slightly reverted snout. Outer lip thick- 

 ened, shouldered at its junction with the body whorl, smooth 

 interiorly. Mouth lanceolate. Colour yellowish white, some- 

 what translucent. 



Dimensions of Type.— Length, 3; In-eadth, l.'lo mm. 



Locality. — Point Franklin, Portsea, Port Phillip, in shell 

 sand. 



Obs. — The shell is the smallest of our smooth forms that 

 Ave have in the genus ; its chief distinguishing character is its 

 shape, which differs from that of any other found here. 



Type in Mr. Gatliff's collection. 



Leiostraca joshuana, sp. nov. (PL XVTTL, Fig. 4). 



Shell minute, fusiform, smooth, glassy, and sufficiently trans- 

 parent to discern the axial pillar through the whorls. A\Tiorls 

 eiglit, including the apical, which are a trifle more vitreous 

 than the rest. Sutures not impressed, and merely define the 

 whorls. The whorls are without varices, but the last three are 

 ornamented with interrupted, ziz-zag, orange-coloured mark- 

 ings, more pronounced on the body whorl, and which uiay be 

 plainly seen through the apei-ture. Aperture pyriform, effuse 

 anteriorly, outer lip thin, and with a callus on body whorl : 

 columella margin nearl}- straight. ' 



Dimensions of Type. -Length, 3 : breadth, 1 mm. 



Locality. — San Remo, type locality (T. Worcester); Port- 

 land (T. Worcester) ; Portsea, Por Phillip ; Shoreham, Western 

 Port. 



Obs. — /.. a<'Mimi7/;rt, Sowb., and /y. lodderae, Hedley, are the 

 other Victorian representatives of the genus, but the present 

 one niaj^ be easily separated by its broader, fusiform character, 

 and the zig-zag markings. It somewhati recalls L. constellatu, 

 Melvill, from Aden. We have named this after Mr. E. C. 

 Joshua, the artist who figured it. 



Type in Mr. ('. J. (rabriel's collection.
