2. The animals of the other genera are oviparous, the eggs being 
deposited in cartilaginous egg-cases like those of the other zoopha- 
gous mollusks. The shell of the just-hatched animal has a regular 
or subregular spiral tip. 
A. The mantle of the animal is enclosed, and the inner lip of the 
shell is defined, or only slightly expanded. 
a. Some have a ventricose shell, with a large expanded aperture, and 
Jive or six strong subequal plaits on the pillar. Foot large, 
and no operculum. 
2. Cymsium. The Melons. 
Shell ventricose, covered with a hard horny periostraca; the 
spire short, depressed, often sunken; aperture very large, ex- 
panded. 
Cymbium Indicum, C. tessellatum, C. Aithiopicum, C. Diadema, 
and C, armatum are found in the Indian Ocean, and probably on the 
north coast of Australia; C. Broderipii at Manilla; C. Miltonis in 
Swan River, Western Australia; C. Georgine and C. umbilicatum 
in Moreton Bay, on the eastern coast of Australia. “ 
In 1833 I described and figured three new species of this genus 
in the Mollusca plates to Griffith’s translation of Cuvier’s ‘ Animal 
Kingdom,’ under the names of Melo Miltonis, M. Georgine and M. 
Broderipii. About the same time Mr. Broderip prepared an essay 
on the genus, which was printed some time after the above publi- 
cation, as he refers to the species and figures. It was to appear in 
the 2nd part of Mr. G. B. Sowerby’s ‘ Species Conchyliorum ;’ but 
this part was not published then. At Mr. Sowerby’s death in 1854, 
Mr. Lumley, the second-hand bookseller, appears to have purchased 
the plates and text, as far as they had been prepared, from the 
executors of Mr. Sowerby, and published it on the Ist of March, 
1855, This part contains the text without the figures of the genus 
Melo, the plates without the text of the genus Cyclostoma, and the 
plates and text of the genera Amphidesma and Terebellum.
