The money cowry is also used as ornaments on the trappings of horses and elephants, as well as on the persons of men and women. The rich yellow variety is much sought after by the chiefs of several island tribes, who permit no one but themselves or their sub-chiefs to wear them. We may truly say that of all the mollusks, large or small, handsome or ugly, the modest little money cowry surpasses any in point of economical importance. In the Friendly Islands the orange cowry (Cypraea aurantia) is used as a badge of chieftainship and for a long time specimens were almost priceless because no one but the chief was allowed to wear this ornament. Specimens of this species are frequently seen in collections, with a hole in the back by means of which it was suspended about the neck of the native chief. Those who have described the Cowries have given them many fanciful names, some of which, however, are quite appropriate. Thus we have the caput serpentis or serpent’s head; the arabica or Arab shell, so named from the peculiar, hieroglyphic-like characters on its back; the lynx, pantherina and tigris, each shell resembling the coat of the lynx, panther and tiger; mus, the rat shell; rhinoceros, the rhinoceros shell; turdus the thrush, and cervus the deer. Many of the other names are equally well chosen, as moppa the mop cowry, and pustulata the pustulose cowry. It is interesting to note the prices that have been paid for rare specimens of this family. At an auction held in London many years ago a specimen of Cypraea guttata brought two hundred dollars, and Cypraea princeps, another very rare shell, brought the same price. Cypraea umbilicata once sold for one hundred and fifty dollars, but may now be had for five dollars. Aurantia, the orange cowry, was once almost priceless, but is now sold at from twenty to forty dollars. Some of the lesser rarities are Cypraea scoltii, worth from five to eight dollars, and Cypraea decipiens, worth from fifteen to twenty dollars. These extravagant prices need not be paid by any one desiring a collection of these pretty shells, for the price of a single rarity will suffice to purchase the majority of the common species. Several private collections in the United States contain from one hundred fifty to one hundred seventy species, including a number of the rarities spoken of above. In connection with the Cypraeas it is interesting to notice other species of shell money which have been used as money. The North American Indians used fragments of shells for money, which they called wampum. In New England wampum was in the form of beads, the manufacture of which required considerable skill. These beads were cylindrical in form, about one-fourth of an inch long and half as wide. They were of two colors and were drilled and strung on long cords.
