28 THE GOLDFISH AND ITS CULTURE. 
Explanation of technical terms used: 
Nudies—Are specimens without scales, quite beautiful, in 
some cases almost transparent to the bones. They are the 
result of ‘“in-breeding.” 
fantati—When two tails are grown together at their upper 
edges, constituting one, and the middle lobe is pointing up- 
ward as the tail of a fantailed pigeon. 
Fringetaii—_Two or more long, drooping tails not grown 
together, each having its own motion. 
Dolphintai_—Two short tails grown together, spreading hori- 
zontally. 
Fan or fringetailed fish must not necessarily have a double 
anal fin in order to be perfect, but, all other points being 
equal, the double anal fin is the more valuable. 
It may be mentioned here, as an advantage of the double- 
tailed fish, that they are unable to jump out of the water. 
This fact is undoubtedly one to be appreciated by those 
keeping an aquarium.
