Salmonid^. 
Salmo. l)r. Murio has described and ligured some dwarfed examples of a 
Salmonoid, hatched from ova which were obtained from pisciculturists, and 
said to be Rhine-Salmon. The fish were kept in a fresh water- tank for four 
or five years, and the author is inclined to regard them as examples of the 
Salmon the ’ development of which was arrested by the outward change of 
physical conditions. Proc. Zool. Soc. 1868, pp. 247-254, pi. 23. Dr. Giin- 
ther states that the examples were undeveloped individuals of some Lake- 
Trout or hybrids, but certainly not Salmo salar. Ibid. p. 214.

Dr. MTntosh. Journ. Micros. Sc. viii. pi. 3.

failure.]
