Melo cylindratus, Broderip. 
Hab. Swan River, Australia. 
This very elegant Swan River Cyméium, named in ho- 
nour of Lord Milton, afterwards Earl Fitzwilliam, is a 
well-marked species, both in respect of form and colour, 
with scarcely any appreciable variation. The upper part 
of the whorls, it will be seen, is peculiarly attenuately ap- 
pressed, so that they drop more than usual in coiling, and 
it follows that the scales have an arched decumbent 
growth, leaving the spire produced and comparatively 
erect. The painting is an elaborate network, shaded into 
bands, and of a uniform purple-chestnut or chocolate 
colour, the columella being bright orange. 
February, 1861.
