THE CALIFORNIAN SALMON. 
best fish, or there would have been a much greater differ- 
ence in their sizes. 
These fish are silvery white on the belly and sides, and 
have eleven or twelve bluish parr-marks very clearly 
distinguishable. The back has three rows of very dark 
green round spots about eighteen in number, and numerous 
small greenish-brown spots above the lateral line. The 
pectoral, ventral, and anal fins are white in colour, the 
caudal, dorsal, and adipose fins are dusky on their outer 
margins. 
The young Salmo solar from the ova presented by 
Sir George Grey and brought in the Chimborazo are 
inches in length, and show the parr-marks distinctly. 
Their growth is very slow at present from the low 
temperature of the water, the spring at which they are 
placed having been swamped by surface water and the 
temperature reduced to 47 deg. 
I carefully examined the salmonoids bred from Tas- 
manian ova. They were caught in a net and drafted into 
two well marked varieties, and probably one of these 
could be again divided into two kinds, although, until 
further developed, it is difficult to do so at present. 
The largest variety is a gray coloured trout, with no red 
spots excepting one faint row along the lateral line. These 
fish have made much more rapid growth than the others 
of the same age. The largest specimen measured inches, 
and the smallest inches. The parr marks are slightly 
distinguishable only in the smaller specimens. The pec- 
toral, ventral and anal fins are yellow, the dorsal has three 
rows of black spots, the caudal has a black margin, and 
the adipose fin is of a pink colour on the tip. A specimen 
sent to Professor M^Coy was pronounced by him to belong 
to Salmo trutta. The fin rays are —
