PLATE IV. 
This is an extremely rare species ; and hitherto, it appears, has 
been only found on the British coasts. It is one of the Cornish 
fishes communicated to Mr. Petiver by Mr. Jago, and described and 
figured by Mr. Ray. 
Mr. Pennant describes it upon this authority, having only seen the 
figure, and Gmelln arranges it from the same authors as a new 
species, under the name of Lineata. 
The most prevalent colour of our specimen is retl, except on the 
belly, -which is -white. The transverse streaks are very remarkable, 
and at once distinguish it from the other species : they consist of 
little thread-like ridges, that pass from the back through the lateral 
line, in a direction nearly parallel with each other, and become ra. 
mose or branching upon the belly. Pennant observes, that by the 
figure above quoted, the nose seems not to be bifurcated, which, 
in our specimen, is particularly characteristic, though the spines are 
small and obtuse. 
This is the only species of Trigla, described by Gmelin, in which 
the number of rays in the fins and tail is not mentioned ; and no 
other author seems to have ascertained them. In our specimen, the 
first dorsal fin has ten rays, and the second seventeen ; pectoral fins 
ten rays ; ventral fin six rays ; anal fin fifteen, and caudal sixteen.— 
'I'his specimen was taken upon the eastern coast.
