time. The remaining 21 were at last planted in the Wailuke River 
near Rainbow Falls. The next day there was a heavy freshet in the 
river, and as the fish were never seen again it is supposed they were 
too weak to resist, and were swept out to sea and destroyed. 
Curp (Cyprinus carpio) were introduced some years ago, and are 
now found on the islands of Mauiand Kauai. On the former they are 
quite common in the irrigation reservoirs and ditches near Wailuku, 
where they were first planted, but are not often sold, as they are not 
popular with the white people and natives owing to their muddy 
flavor. The Japanese and Chinese catch and eat them. On Kauai 
they are found in irrigation ditches and in a few of the fish ponds. 
They are sold principally to the Japanese and Chinese. 
Cat-fish.—About ten years ago the late Charles Arnold, of Hilo, 
introduced the cat-fish (Amezurus nebulosus), which he secured from the 
mainland. They were placed in various ponds in Hilo, but none has 
ever been seen since. Another species (Jlacropternotus maqur) was 
introduced from China a few years ago and is now occasionally found 
in the fresh waters near Honolulu. 
China-fish (Ophiocephalus).—This species, brought by the Chinese 
from China, is now fairly common in the vicinity of Honolulu. It is 
commonly raised in the irrigation ditches and fresh-water ponds and 
generally sold alive to the Chinese. 
Goldfish (Carassius auratus).—These were introduced originally 
from China, but there is no record as to the date. As early as 1867 
shipments of them were being made to San Francisco. They are raised 
principally in the irrigation ditches around Honolulu. A few are also 
found on the larger of the other islands, especially near Wailuku, on 
Maui. They are sold alive in the market and are eaten mainly by the 
Chinese and Japanese. 
Salinon.—In 1876 some salmon and trout eggs were given to parties 
in Honolulu by the California Fish Commission in exchange for 100 
awas, which it designed planting in California waters. ‘There is no 
record of what became of the eggs. 
Trout.—The first introduction of the trout was, as stated above, 
when the California Fish Commission shipped some eggs to Honolulu 
parties. In 1894 a consignment of 1,000 brook trout (Salvelinus fon- 
tinalis) was secured from the California Fish Commission and planted 
in the Waimea River, on Kauai, but they were soon lost sight of. 
About 1896 a dozen trout were brought to Hilo and planted in the 
Wailuke River near Rainbow Falls, but nothing was ever seen or 
heard of them afterwards. As the streams either dry up entirely in 
the dry season, or become mere pools, in which the water gets very 
warm, trout are not suitable for them, as they require pure, cold water. 
Frogs.—The date of the introduction of the frog is uncertain, but 
it is known that some were introduced previous to 1867. In the latter
