I know of only two specimens which I have figured. Fig. I 

 represents a perfect shell just about to develop the Aving ; fig. 2" 

 wants the pullus and the basal part of the body-whorl, the 

 angular body-and spire-whorls of which are similar to those of 

 the other specimen, and therefore I think it not unreasonable to 

 view the two as individuals at different stages of growth of the 

 same species. 



This species is named in honour to Mr. Alexander Morton, of 

 Hobart Museum. 



V. Mortoni is evidently closely allied to F. macroptera^ but it 

 is distinguished from it by its shorter spire, different pullus, and 

 angulated whorls. 



9. Voluta limbata, Tate. 



Reference. — Gastropods part I., plate xiii., fig. 8 (1888). 



Shell oblong and sub-cylindrical, spirally and transversely 

 striate ; spire short, terminated by a rounded pullus ; columella 

 with four well-developed plaits, increasing in size from the base 

 backwards. Sutures and spire-whorls concealed by the free hori- 

 zontal foliaceous expansion of the posterior margin of the preced- 

 ing whorls. Last whorl faintly angled at the periphery, which 

 is also defined by about ten inconspicuous angular nodosites. 

 The spire-whorls and posterior part of the last whorl sculptured 

 with delicate wavy lamellae crossed by transverse folds and striae; 

 the spiral ornament is the stronger, but on the anterior area of 

 the body-whorl, the transverse lines and folds are alone conspicu- 

 ous, as the spiral stride are obsolete, or Adsible only by the aid of 

 a magnifier. 



Dimensions. — Length, 32*5; width, 15; length of aperture, 2 7 -5. 



Locality. — Blue clays at Schnapper Point [R.T.) 



This species and the next belong to the Section Voluto-conus, 

 uniquely represented by Y. coniformis (Cox), inhabiting the north- 

 west coast of Australia, from which they differ in the angulated 

 periphery, more or less nodulose ; and this species by the retro- 

 flexed posterior margin of the whorls. 



10. Voluta conoidea, Tate. 



Reference. — Gastropod's part I., plate xiii., fig. 9 (1888). 



Shell coniform, with a short spire, ending in a moderately mam- 

 illate pullus of three and a half turns, the last half turn some- 

 times crenulated. The first and second spire-whorls almost 

 wholly embraced ; the penultimate whorl is broadly depressed 

 near the middle line, and slightly varicose over the posterior 

 suture ; the last whorl is faintly angled at the periphery, which 

 is also defined by seven transversely elongate nodosites, posterior 

 to which is a slightly concavely depressed zone. Outer lip sharp, 

 slightly inflected in the middle. Columella with four well-
