locality ; and, so far as I am aware, no other specimens have yet been 

 found. It differs from any of the Cassididce that I have met with in 

 its thin texture and its pure white colour ; the deep rounded furrow or 

 excavation at the angle makes it at once a most conspicuous species. 



2. Cassis sophia. (Plate XLIV. fig. 2.) 



Shell globosely inflated, rather solid ; spire moderately raised, 

 apex rather obtuse ; whorls 5§, tabulated above, spirally grooved 

 next the suture, the last whorl obliquely striated and transversely 

 distantly finely ridged, more than four fifths the length of the shell, 

 deeply grooved at the base ; columella arched, concave, faintly 

 wrinkled, expanded and covering the perforation ; whitish, the last 

 two whorls ornamented with rows of large fulvous-red square blotches ; 

 lip reflexed and toothed, the teeth on the basal portion nearly ex- 

 tending across the lip, obsolete at the upper part. 



Length 2 inches 9 lines, breadth 2 inches 4 lines, height 2 inches. 



Hab. Under Grassy Head, mouth of the Macleay River, north of 

 Port Jackson, New South Wales (coll. Brazier). 



I obtained this example during a stay of one week at the mouth 

 of the Macleay River. I also obtained broken and beach-worn ex- 

 amples at the mouth of the Nambuccra River, twelve miles further 

 north ; but from that to the Clarence River, some hundred and fifty 

 miles, I found no more traces of the species. 



3. Cypr^ea coxi. (Plate XLIV. figs. 3, 3 a.) 



Shell oblong- oval, rather thin, base almost flat ; sides rounded, 

 anterior end contracted and moderately prominent, posterior end 

 produced ; aperture narrow, nearly straight ; teeth thick, obtuse, 

 yellowish white, on the outer edge 13 in number and confined to the 

 margin of the aperture, on the columellar side from 15 to 16, the 

 four lower ones rather prominent, the others almost obsolete ; light 

 orange-yellow or cream-colour, smooth and polished, ornamented 

 with two faint yellowish-white bands, with a faint indication of lon- 

 gitudinal hair-like lines ; interior cream-colour. 



Length 10, breadth 5|, height 5| lines. 



Hab. Dupuch's Island, north-west coast of Australia (coll. 

 J. C. Cox). 



This species was collected by Mr. Thatcher, about four years ago, 

 at the above locality.

1. Helix (Microcystis) catletti. 



Shell imperforate, depressedly turbinate, rather thin, wrinkled on 

 the upper part, rather shining, horny-green, with a pale yellow
