110 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 



light bronze reflections to within an inch of the lateral line, with black 

 linear spots on the same ; tail and dorsal fin, speckled ; head small and 

 pointed; ventral tins commence nearly as far back as the dorsal ends; 

 scales very small and bright. At this date they are still scarce." 



A tsah-kwai obtained by Dr. Kennedy at L. Chiloweyuk, September 8, 

 1858, had, according to the doctor's notes, a length of 3 feet, 10 inches, 

 (nearly 4 feet,) and an abdominal circumference of 1 foot, 10 inches. 

 Black sj)ots on the tail as large as a buck-shot; those of the dorsal tin 

 oblong. Greneral color, silvery-grey with metallic lustre. Lateral line 

 very distinct. Sides above the lateral line with irregular black spots. 

 Snout projects a little when the mouth is closed. Head 8 inches long. 



This species was in good condition and abundant at Ghiloweyuk at 

 date. He also adds: "This species is the largest found in these waters. 

 Its meat is quite white and not so much esteemed as the suTc-keh, which 

 has red meat." In speaking of a young specimen he says: "The spots 

 are quite distinct, i)erhaps of larger size in proportion than those of the 

 adult."

Sp. Oh. — Body fusiform, compressed; head forming the fourth of the 

 total length, caudal fin excluded; upper jaw longest. Maxillary gently 

 undulating, its posterior extremity extending to a vertical line passing 

 considerably behind the entire orbit. Anterior margin of dorsal fin 

 ecjuidistant between the tip of the snout and the base of the caudal. 

 Ground color, greyish-silvery above; sides and belly, yellowish-orange; 

 dorsal fin spotted. — Girard. 



The two specimens from Astoria still remain in the Smithsonian col- 

 lection. No others have been received since their arrival in 1851. Dr. 

 Girard's description (based upon the characters of what appear to be 

 young of immature fish) gives very uncertain data for the ideutiflcation 

 of adults of the species. The typical specimens are numbered 563 on 

 the museum register. 



Collectors near the mouth of the Columbia would do well to preserve 

 for study and comparison several small (healthy) red salmon, if they can 

 be obtained.

 the characters of two young, partially grown fish, the specific characters
