In the Sacramento River is occasionally taken 



781d. SALMO IRIDEUS STONEI (Jordan). 

 (NISSUEE TEOUT; NO-SHEE TROUT.) 



Anal rays 11. Depth 4 in length. Pectoral \\ in head. Eye large, 4- 

 in head. Maxillary 2- 1 1 j. Distinguished by its small scales, the number 

 of scales in a longitudinal series being about 155, 82 before dorsal, where 

 they are small and embedded, 25 above lateral line. Teeth fewer and 

 smaller than in var. shasta, those on the vomer in a single zigzag series. 

 Axillary scale of ventral small. Upper parts plain greenish; spots few, 

 and confined chiefly to posterior part of body; spots small and sparse 

 on dorsal, adipose fin, and caudal ; a red lateral band usually distinct; 

 cheeks and opercles with red ; no red between branches of lower jaw. 

 Described from a specimen 14 inches in length, collected by Livingston 

 Stone in McCloud River at Baird, California. This form is well known 

 to Indians and to fishermen on the Upper Sacramento. According to 

 Mr. Stone, the Indian fishermen say that it is abundant in the McCloud 

 River, about 8 miles above Baird. They are larger in size than the 

 ordinary irideus, one having been taken weighing 12 pounds. A second 

 specimen is deeper in color, the red lateral band very distinct (female 

 taken in May). The scales rather larger (140) and irregularly placed. 

 (Named for its discoverer, Livingston Stone, Superintendent of the 

 United States Fish Hatchery at Baird, in recognition of his valuable ser- 

 vices in the propagation of salmon and trout.)
