with protruding eyes). The former was first introduced from China toward 
the close of the Japan-China war (1894-95). It has protruding eyeballs, 
and the body and the caudal fin are short. It is not usually bright colored, 
being black all over the body or yellowish red variegated with black spots or 
irregular patches. The deme ranchu, first brought from China six or seven 
years ago, has a globular body and, like the ranchu, no dorsal fin. ‘The eyes 
not only protrude. but also are turned upward go degrees. (Pl. xx1r and xx1m.) 
The foregoing are varieties for some time cultivated in Japan or recently 
introduced from China. New varieties, however, different from these, have 
lately come into existence, and I shall now describe how and in what order 
these have been produced.

‘“‘Watonai.’’—When the Fisheries Exhibition was held in Tokyo in 1883, 
I saw there exhibited a highly interesting variety of goldfish, which was a wakin 
with a flowing caudal fin. Being struck with its extreme peculiarities, and 
inquiring how this variety came to be produced, I found that the exhibitor, 
who lived at Imaidani, Akasaka, Tokyo, had only one pond for breeding goldfish, 
and that there the said variety was produced. As in that pond all the different 
varieties just stated above were reared together, the strange new variety appeared 
to be a cross between the ryukin and the wakin; but I did not make at that 
time further investigation into the cause. That breed was called ‘‘watonai,” 
which means ‘‘a variety hitherto found neither in Japan norinChina.” (Pl. xxiv.)
