Theusual development period, however, is from three to five months. Shouldthey pass ten months without turning, they may be safely called Japanesefringetails. Many such fishes that have come from telescope stock areused to breed to telescopes to produce telescopic young. This is usuallysuccessful in the first generation, but it has a tendency to spoil the breedby gradually reducing the size of the eyes. Telescope fishes of the presenttime are, for the most part, considerably inferior in point of eyes com-pared with the stock of fifteen years ago, due mainly to breeding too ex-clusively for short bodies and long fins. Type characteristics in any kindof breeding can. like liberty, only be maintained at the price of ^/-/^lliii|«,t>!--~
