THE SAURY PIKE OR SKIPPER (sw. makrilgapdan"). 
SCOMBRESOX SAURUS. 
Fig. 93. 
Both jaws , in adult specimens, elongated into a beak. Length of the postorbital part of the head, in specimens 
150 mm. long, about % of that of the lower jaw , and in specimens 300 — 400 mm. long, scarcely half or even 
only about 35 % thereof. Coloration like that of the Garpike, but until a more sharply marked longitudinal band 
of silvery lustre on the sides just below the back, which is of a lustrous greenish blue.

The Saury is very like the common Garpike, in 
spite of the distinction drawn between them, at the 
first glance, by the finlets behind the dorsal and anal 
fins. The body, however, is deeper 0 and more com- 
pressed d , the lateral compression of the belly being 
particularly strong. The jaws are more slender, some- 
what turned up at the tip, and furnished with much 
weaker teeth of uniform size, which are set in two 
rows only in the back half of the lower jaw and a 
corresponding, though smaller, portion of the upper 
jaw. With this exception the teeth are set in one row. 
The zigzag bony ridge in the lower jaw, on the other 
hand, is higher and thicker. The preorbital bone does 
not cover the lateral parts of the interinaxillaries so 
completely as in the Garpike, a fairly broad part of 
these bones, somewhat widened interiorly, remaining 
visible when the mouth is closed. The nasal orifice 
is more compressed and almost T-shaped. The eyes 
are more oblong 0 . The relative length of the head in 
full-grown specimens is about the same as in middle- 
sized specimens of the preceding species. The pectoral 
fins are somewhat shorter, always distinctly shorter 
than the postorbital part of the head, and more con- 
cave (falciform) at the inferior margin: sometimes, in 
“ Nilsson, Skand. Fauna , I. c. 
6 Sometimes 2, according to Lutken. 
c In the Saury the greatest depth of the body varies between 9 V., and 12 % of the length of the body. 
d The greatest breadth (thickness) of the body (across the occiput) varies between about 47 mid 53 % (according to Kroyer some- 
times 57 %) of the greatest depth thereof. 
The longitudinal diameter of the eye in full-grown specimens is between about 2 5 and 1 ;{ of the length of the postorbital part 
of the head.
