286 ME. E. A. SMITH ON THE 



80. Phtsa peodtjcta, n. sp. (Plate YI. fig. 21.) 



Shell elongate, of a yellowish olivaceous colour, somewhat 

 strongly striated by the lines of growth ; spire elongate, acumi- 

 nate. Whorls 6-7, convex, regularly increasing, the last some- 

 times faintly constricted beneath the suture, which is very oblique 

 and occasionally narrowly marginate. Last volution elongate, a 

 little inflated. Aperture obliquely inversely auriform, acute 

 above, generally less than half the entire length of the shell, but 

 sometimes longer. Columellar fold thin, moderately prominent, 

 white. Callus on the paries thin, extending to the lip above. 

 Labrum, viewed laterally, obliquely arcuate, very slightly siuuated 

 near the suture. 



Length 26 millim., diam. 10 ; aperture 12^ long, 5 broad.

This species is rather narrower in the body-whorl than P. gih- 

 bosa, var. Adamsiana, Canefri, and those of the spire are perhaps 

 more regular in their enlargement. The colour, too, is not so 

 olivaceous, being rather yellower in tint. P. attenuata, Sowerby, 

 from Tasmania, has a less acuminate spire, and the body-whorl is 

 conspicuously narrow in proportion to the preceding whorls. P. 

 aihbosa, however, may eventually include this species, as certain 

 slender forms approach it very closely. 



81. Phtsa Brazteei, n. sp. (Plate VI. fig. 22.) 



Shell short, ovate, subglobose, glossy, pellucid, horny brown, 

 striated feebly by the lines of growth, and crossed by spiral, more 

 or less punctate striae, some of which are rather remote. Whorls 

 4, rapidly enlarging, convex ; last large, subglobose. Aperture 

 broadly subauriform, acutish above, rounded below, occupying 

 about two thirds of the whole length. Columella simple, arcuate, 

 exhibiting no fold, covered with a greyish callosity extending to 

 the lip above and reflexed in the umbilical region, thus producing 

 a narrow rimation. Labrum, viewed laterally, almost straight, 

 not arcuate in the middle. 



Length 12 millim., greatest diameter 7^; aperture 7^ long, 

 4 broad. 



Var. a. Shell of a pale horn-colour. 



Var. b. Shell larger than type, spire a little shorter, aperture 

 a little longer. Colour of a pale horn tint. 



Hai. Ashfield, near Sydney {Brazier).
