COMMON TRO’DT.

round that lake is formed of black and white granite; the 
bottom of the loch of large boulders of granite gravel, or fine 
sand; and, except at the edge of one or two small bays, no 
indication of moss appeared. The colour of the water was clear 
sienna brown, and more limpid than that of any of the lochs 
of the same district. The fish were of good size, and in form 
came near to the accepted idea of symmetry in a Trout; 
remarkable for the small size of the head, arched back and 
great depth; the colours Avere of the highest brilliancy, the 
upper parts of a rich brown, the lower half and belly a deep 
golden orange, the spotting numerous but ill-defined, and often 
of a cruciform shape; the flesh high-colourcd. 
We notice this description more particularly, because on some 
wild downs in the parish of Luxulian, in Cornwall, there are 
large pools in a granite district, in which there are Trout much 
like those of Loch Craigie, and probably from the operation 
of a like cause. These pools are in an open country, and have 
the appearance as if they had been formed by some ancient 
workings for tin, and are not connected Avith any river; so that 
it is not easy to form an opinion how it has happened that 
any fish could have had access to them. Minnows exist in 
these pools, and probably constitute the principal food of these 
orange golden-coloured Trout. However, there are in the same 
pools some Trout of a larger size and different form, as Avell 
as colour, so as to raise the supposition of their being a different 
species. The first-named have the anterior margin of the dorsal 
fin and also the adipose red; the upper and lower portions of 
the tail not rounded, and both the margins red; with no 
light line on the anterior border of the anal. In the larger 
fish there is not a mark of red either on the body or fins; a 
slight tinge of yellow on the cheeks, and on the body some 
crossly-marked spots; points of the tail rounded; anterior border 
of the anal faintly white. 
The second variety noticed by Sir William Jardine is found 
in Loch Shin, Avhich is of great extent and depth, on a lower- 
level than Loch Craigie, although only three or four miles from 
it. The bottom is for the most part rocky, gravelly, or sandy, 
but to a great extent its banks are mossy, and the water is of 
a very deep brown. The Trout were in a good condition, but 
remarkable for the lengthened and graceful form of the body
