Salmo orcadinsis. GOnthkr's Cat. vi. ji. 91. THIS species is said to be very similar to S. iiigripinnis, "but distinguished from it by a broader and stronger maxillary, larger scales on the tail, and a greater number of pyloric ; It is thus described by Giinther:—"Head well proportioned in its shape, and rather short when compared with the body; body rather slender Pr?eoperculum with the lower limb very indistinct; snout short, conical. Maxillary as broad and as strong as in 5. fario; in specimens nine inches long it does not extend to below the posterior margin of the orbit. Teeth moderately strong; those of the vomer form a single series, and are persistent. Fins well developed: pectoral somewhat rounded, its length being more than one half of its distance from the ventral. The caudal fin is distinctly emarginate in specimens nine inches long, but nearly perfectly truncate in specimens twelve inches long: it has the lobes pointed. Scales on the hinder half of the tail considerably larger than on the sides of the trunk: there are about thirteen in a transverse series descending from behind the adipose fin obliquely forwards to the lateral line. Sides with more or less numerous black reticulated spots, between which a few red ones are interspersed. Dorsal with black spots. Probably a non-migratory species, from Loch Stennis, in the Orkney ; The fin-ray formula is Dorsal 13. Pectoral 14. Anal 11.
