well as hardy, and well suited to the needs of the beginner. 



Then comes the group, including practically all of the 

 most remarkable varieties, in which the tail and also the 

 anal fin are in duplicate. With most creatures, when abnor- 

 mal repetitions of parts occur, the individual is unable to 

 survive. In the goldfishes, however, the probably fortuitous 

 appearance of monsters has led to the development of the 

 finest breeds. 



The Japanese Fan-tail is the simplest representative 

 of this type, and is always obtainable from dealers. It is 

 not in good repute among breeders of fancy fishes, as many

This fish undoubtedly was the forerunner of the truly

Beside the Veil-tail proper, there are two minor sub-

 approaching perfection. Oriental breeders seem next to
