The Gudgeon, according to Bloch, attains a length 
of 8 in. (21 cm.), and Pennant was told of a specimen 
that weighed half-a-poimd; but in Scandinavia it always 
belongs to the small fishes, being at most about 15 cm. 
long. The body is elongated and fairly thick, with 
broad, convex back, flat belly, and more or less per- 
pendicular sides. The greatest depth of the body, which 
occurs just in front of the beginning of the dorsal tin, 
measures about 16 — 1 8 1 / 2 % of its length, and the 
greatest thickness, across the opercula, is about 2 /s of 
the greatest depth. The least, depth of the tail is about 
8 (sometimes 8V 2 ) or 7 % of the length of the body. 
The dorsal profile thus forms a very elongated curve, 
which generally shows quite a distinct depression at 
the occiput. The ventral profile is straighter in front 
and ascends, strictly speaking, only behind, at the be- 
ginning of the anal fin. 
The form of the head, bluntly pointed in front, 
otherwise passes evenly into that of the trunk, but is 
diversified in the nasal region, just in front of the eyes, 
by a swelling, which, according to Lilljeborg, is larger 
in the males than in the females — a statement of which 
we have failed to find corroboration in our specimens
