continuous, but the band usually consists of a series of blotches 

 more or less coalescent ; the enamelled band is coloured similarly, 

 but in the form of dashes, which obliquely cross the suture and 

 are there reversely bent, and continue thus round the spire, the 

 intermediate marking between the bands on the body whorls are 

 spirally zigzag, interrupted, and very light brown in colour. 



Length, 18 mm. ; breadth, 6 to 7 mm. ; length of aperture, 

 9 mm. ; maximum breadth, 3 mm. 



Habitat. — Rosebud, Port Phillip, and Western Port. 



Observaimis. — It is more narrowly acuminated, and the spire 

 is proportionately more lengthy than in any other living species 

 that we know of ; its nearest ally is A. iitieata, Kiener, for which 

 species it has been mistaken ; but it may be readily distinguished 

 from it by its much more slender form and its numerous spiral 

 grooves. We have two specimens from Spencer's Gulf, S.A., the 

 prevailing colour of which is brown, and they are not so large as 

 our shell ; they have there been erroneously identified as A. 

 tricolour., Gray, described as a Cape York species, now considered 

 to be the young form of A. ajistralis, Sowerby. 



We have named this shell after Mr. Gatliff's eldest daughter 

 Edith, who has given much assistance in searching for and 

 sorting out the various species of shells. 



Cancel laria maccoyi, \\. sp. (PL XX., Fig. 6.) 



Shell ovate ; whorls 5^ rounded ; suture impressed ; spirally 

 grooved, grooves on the body whorl numbering from 26 to 31, 

 and on the penultimate whorl 12, the grooves are U-shaped, and 

 following at fairly regular intervals from the base, until reaching 

 about the centre of the body whorl, where the distance between 

 them is greater, but becoming much closer at the shoulder, until 

 the suture is reached ; the area between the grooves is flat, and, 

 under the lens, finely, irregularly, transversely striated. 



Aperture narrowly ovate ; outer lip acute, lirate within ; 

 columella usually triplicate, rarely quadriplicate. 



Of a cream colour, with, on the body whorl, two broad light 

 brown bands (visible in the interior), and a narrower one with a 

 tendency to inaculation immediately below the suture. 



Dimensions. — Length of type, 19 nun.; breadth, 11 mm.; 

 length of aperture, 11 mm. ; breadth, 5 mm.
