They were stated to agree with that species, with several 
Indian ones, and with Trigla pceciloptera of the Mediter¬ 
ranean, in their large pectoral fins being ornamented 
with eye-like marks similar to those on the wings of some 
lepidopterous insects. One of them, Trigla polyommata, 
has minute cycloid scales on the body, an unarmed lateral 
line, and the dorsal plates confined to the first dorsal, 
there being no dilatation whatever of the interspinous 
bones of the second dorsal. All the spines of the head 
are stiletto-shaped ; and one, whose base occupies the 
whole anterior end of the infraorbitar on each side, pro¬ 
jects boldly beyond the snout, and gives the fish a very 
different aspect from any other known gurnard. 
The other may be thus characterized :—

Trigla Vanessa has a spinous infraorbitar tooth, larger 
than usual in gurnards, though not so remarkable as in 
the preceding species, and not occupying the whole end 
of the bone, there being a smaller tooth and some granu¬ 
lations beneath it. The arming of the dorsal furrow 
extends to both fins, and is formed by saddle-shaped 
dilatations of the interspinous bones, with a triangular 
spinous tooth on each side of each plate directed back¬ 
wards. The scales of the body are rather large, and are 
studded on their uncovered portions with minute spiny 
points; those forming the lateral line are tubular both 
transversely and longitudinally, and are armed with 
several strong spines also tubular. There is a black
