CALLIOSTOMA PUNCTULATUM (kalos, beautiful; 
stoma, the mouth; punctulatum, having dots scattered over 
the surface).—A spiral univalve with well-rounded whorls, 
of a dark chestnut brown colour, covered with white 
granules in regular rows round the whorls, the granules 
and intervals being equally spaced. The aperture is 
rounded, the interior ribbed and nacreous. The shell is 
of hard texture; consequently, when washed ashore it is 
rarely broken. To the touch, the surface is very similar 
to shagreen, a leather prepared from sharkskin, and at 
one time much used for spectacle cases and other small 
articles, such as handles of swords, etc. It attains a height 
of one and a-half inches and a diameter of the same.

CALLIOSTOMA SELECTUM (kalos, beautiful; stoma, 
the mouth; selectum, select, choice).—This 1s a fairly large 
shell, conical, with the outlines almost straight, of a very 
pale fawn colour, with pale reddish-brown spots on the 
spiral ribs. The refined or subdued tone of the colour 
scheme in this species no doubt gave rise to the specific 
name, selectum. ‘The spots of darker colour, on the slightly 
granular ribs are elongated, in a spiral direction. The 
columella is arched and pearly, and, like the interior, is 
nacreous. Large specimens are two and three-quarters 
inches wide by two and a-half inches high. It is not a 
common shell, and is to be found washed ashore on sandy 
beaches after heavy winter storms.

CALLIOSTOMA TIGRIS (kalos, beautiful; stoma, 
the mouth; tigris, a tiger ).—This is a handsome and rather 
rare univalve shell of a bright and rich red-brown colour, 
with more or less tiger-like markings. The principal feature 
is the waisted tapering form of the spire, which is high 
and finely pointed. The interior is beautifully iridescent 
and pearly; the outer lip is sharp, with a narrow band of 
chestnut bordering the inner margin. The inner or columel- 
lar lip is pearly, and the sculpturing consists of numerous 
very finely-beaded ribs, spirally arranged round the whorls. 
The largest-sized shells are about two and a-half inches 
in height and two inches in diameter. From below low-
