83. Phtsa Quoti, n. sp. (Plate YI. fig. 24.) 



Shell elongate, narrow, pale horn-colour, scarcely semitrans- 

 parent, not very glossy, striated moderately distinctly by the lines 

 of growth. Spire somewhat produced, rather suddenly diminish- 

 ing, and becoming acute above the penultimate whorl. Apex 

 brown, small. "Whorls 6, convex, penultimate inflated, very 

 oblique ; last subcylindrical, narrow, convex, rather rapidly de- 

 scending near the lip. Aperture small, inversely subauriform, 

 narrow, less than half the soell in length, feebly stained with 

 brown within at the base. Lip, viewed laterally, very oblique, 

 having an almost straight edge, and exhibiting scarcely any arcua- 

 tion or sinuosity. Columellar fold rather high up, not prominent, 

 reflexed, thus producing an umbilical rimation. 



Length 15 millim., greatest diameter G ; aperture 7 long, 3 

 broad. 



Sab. King Greorge's Sound, South-west Australia (Brazier). 



This species is remarkable for the cylindrical body-whorl and 

 manner in which it descends on approaching the aperture ; the 

 latter, too, is small, and the sutural line very oblique. The spe- 

 cies is named after one of the authors of the molluscan portion 

 of the ' Voyage de I'Astrolabe,' who has described the only other 

 species hitherto known from the south-western part of Australia. 



84. Phtsa Ethekidqii, n. sp. (Plate VI. fig. 25.) 



Shell small, ovate, acute, very pale horn-colour and transparent, 

 streaked at intervals longitudinally with opaque creamy stripes, 

 brownish at the apex. Spire rather acute, frequently eroded at 

 the tip. Whorls 4-41 convex, rapidly increasing ; last narrow, 

 ovate, somewhat attenuated at the base. Aperture elongate, 

 auriform, narrow, occupying nearly three fourths of the entire 

 length of the shell. Columellar twist rather high up, thin. Labrum 

 oblique, arcuate in the middle, and feebly sinuated beneath the 

 suture. Sculpture consisting of fine lines of growth and more or 

 less indistinct spiral stride. 



Length 11 millim., greatest diameter 6 ; aperture 7 long, 

 3 wide. 



Mab. Yan-Yean Eeservoir, Plenty district, Victoria, S. Aus- 

 tralia {Etlieridge). 



This species resembles in some respects P. acutispira, Tryon. 

 The spire, however, appears to be not so slender, and the colour 

 also is difierent. The opaque creamy stripes seem to be a character
