git River which we have referred to 8. masoni. The total leugth of this 

 fish was 12.75 inches, and the distance from snout to dorsal lin 5.75. 



" Colors. — Back and sides above hiteral line sprinkled with small spots 

 of irregular shape, black on the back, on the sides hliie, with a black 

 edge behind. Behind the anal spotted below the line. Sides, as far 

 back as anal fin, with a broad streak of lake-red. Dorsal and caudal 

 spotted with black. Back, dark brown, approaching to black, with blue 

 reflections. Belly, yellowish-red. Head partly spotted above, on the 

 snout and on the preopercula. 



"Head, short and blunt. Tail, slightly lunated. Another specimen 

 had small specks along the belly, and the colors were lighter, with more 

 red. 



" Much larger specimens were taken, but the meat in every instance was 

 white. Mr. Gibbs obtained a fish, apparently similar, from the waters of 

 the Sunilkamun, flowing into another basin ; but this had red flesh, and 

 lacked the broad streak along the sides. [This latter is probably an 

 eflect of age or sexual excitement.] The lateral line was red." — Gibbs' 

 Mss. 



Two species of trout were taken in the mill creek, east of the Colum- 

 bia, at Fort Colville, through the ice. One, with red flesh, is known as 

 the humddna, and is the larger — [S. gihhsiil) the other is the 2)eestl, and 

 is the common black-speckled brook-trout. "Again," Mr. Gibbs re- 

 marks, " the Indians say that the Feestl has the dashes of carmine under 

 the jaws which the RumdCuia lacks. They also say that it is the male 

 fish which has a reddish tinge on the belly." * * * On the 2d of 

 April " found the Indians at the crossing of the Little Spokane taking 

 the Humddna in small numbers. A female had the roe entirely de- 

 veloped."
