Distribution
Newcombia cumingi, is the only known species of the genus Newcombia from the island of Maui, Hawaii, while six other species of Newcombia live on Molokai. The current location occupied by this snail is on private property.
Historically, it was distributed from the West Maui Mountains to the slopes of Haleakalā volcano. Snails were reported from relatively low elevation locations (probably around 1,000 feet (300 m) and up to over 3,280 feet (1,000 m) above sea level. Until October 1994, the last documented sightings of this snail species were in the early 1900s near Lahaina, Wailuku, and Makawao.
In 1994, private natural resource personnel located a small population of Newcomb’s tree snails while monitoring transects for alien species in the mountains of west Maui in the Puu Kukui Reserve. This is the only currently known population. It is located on a single ridge on the northeastern slope of West Maui. The area inhabited by Newcomb’s tree snail extends from 2,412 feet (735 m) to 2,641 feet (805 m) in elevation and does not exceed 6.18 acres (2.51 hectares).

Famous quotes containing the word distribution:
“The man who pretends that the distribution of income in this country reflects the distribution of ability or character is an ignoramus. The man who says that it could by any possible political device be made to do so is an unpractical visionary. But the man who says that it ought to do so is something worse than an ignoramous and more disastrous than a visionary: he is, in the profoundest Scriptural sense of the word, a fool.”
—George Bernard Shaw (1856–1950)
“There is the illusion of time, which is very deep; who has disposed of it? Mor come to the conviction that what seems the succession of thought is only the distribution of wholes into causal series.”
—Ralph Waldo Emerson (1803–1882)
“The question for the country now is how to secure a more equal distribution of property among the people. There can be no republican institutions with vast masses of property permanently in a few hands, and large masses of voters without property.... Let no man get by inheritance, or by will, more than will produce at four per cent interest an income ... of fifteen thousand dollars] per year, or an estate of five hundred thousand dollars.”
—Rutherford Birchard Hayes (1822–1893)
