50 strings = 1 head of Cowries.
10 heads = 1 bag.
2,000 Cowries = 1 head.
3 heads = 1 dollar.
20,000 Cowries = 1 bag.
In other places the value is about 1s. 3d. for 1,000 shells.
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.
