Ijotli Jua-s, ill adidt specimens, cldiii/dfed into a beak. Lenfjili of the postorlital part of tin- licad, in specimens 



150 mm. lonfi, about 7:) of that of the hirer jair, and in specimens 300—400 mm. lomj, scarcpli/ half or even 



only aljoiit 3.5 % thereof. Coloridion like that of the Garpike, hut u-ith a more sharply marked longitudinal hand 



of silvery lustre on the sides just heloir the hack, which is of a lustrous yreenisJi blue.

Tlie Saury is very like the coninioii (jarpike, in 

 spite of the di.stinctioii drawn between them, at the 

 ■first glance, by the hiilets behind tlie dorsal and anal 

 fins. The body, however, is deepei'' and more com- 

 pressed'', the lateral compression of the belly being 

 particularlj' strong. The jaws are more slender, some- 

 what turned up at the tip, and furnished Avith 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 tlie ujiper 

 jaw. With this exception the teeth are set in one row. 

 The zigzag bony ridge in the IoAV(;r jaw, on the other 

 hand, is higher and thicker. The preorbital bone does 

 not cover the lateral parts of the interniaxillaries so 

 completely as in the Garpike, a fairly broad jiart of 

 these bones, somewhat widened inferiorly, remaining 

 vi.sible when the mouth is closed. Tlie nasal orifice 

 is more compressed and almost T-shaped. The eyes 

 are more oblong''. 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 

 tins 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, Skaiul. Fauna, 1. c. 

 * Souietiuies 2, according to Ll'tkkn. 



"■ in the Saury the greatest depth of the body varies between 9' ., and 12 \ of the length of the body. 



'' The greatest breadth (thickness) of the body (across the occiput) varies between about 47 and 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 - ^ and ' ., of the length of the postorbital part 



of the bead.
