XIX. An Account of a new Eledirical Fijh. In a Letter from 
Lieutenant William Paterfon to Sir Jofeph Banks, Bart . 
HILE at the iftand of Johanna, one of the Comora 
iflands, in my way to the Eaft-Indies, with the 98th 
Regiment, I met with an eleCtrical fifh, which has hitherto 
efcaped the obfervation of naturalifts, and feems in many re- 
fpeCts to differ from the electrical fifties already delcribed % 
which induces me to fend you the following account of it, 
with a very imperfeCt Drawing, and to beg that, if you think 
it deferves attention, you will do me the honour of prefenting 
it to the Royal Society. The fituation of a fubaltern officer, 
in an army upon foreign fervice, will, I hope, Efficiently 
apologize for my fending you fo very imperfeCt a Iketch of 
the fifh, which was made in the field, in a hot climate, under 
every difadvantage. 
The fifh is feven inches long, two inches and a half broad, 
has a long projecting mouth, and feems to be of the genus Te- 
trodon. The back of the fifh is a dark brown colour, the belly 
part of fea-green, the fides yellow, and the fins and tail of a 
fandy green. The body is interfperfed with red, green, and 
white fpots, the white ones particularly bright ^ the eyes large, 
the iris red, its outer edge tinged with yellow. (See Tab. XIII. )
