from Kamchatka* and Unalaska to San Francisco ; abundant in Puget 

 Sound, but rather rare among the Aleiitian Islands, and scarcely known 

 south of Cape Mendocino ; erroneously recorded from Japan, where Hexa- 

 (jrammos otaMi, Jordan & Starks, has been mistaken for it. (Named for 

 Georg Wilhelm StoUer, the indefatigable naturalist of Bering's voyage. )

2261. HEX.\GR.UmOS SUPERCILIOSUS (Pallas). 



(Red Rock Trout.) 



Head 4; depth 3i. D. XX, 23; A. 22; scales 107. Body rather robust ; 

 supraorbital dap long and slender, densely fringed, its length about equal- 

 ing vertical diameter of orbit. Scales mostly cycloid, a band of ctenoid 

 scales often present on postaxial region; 8 or 9 scales in an oblique 

 series between second and third rows of pores. A small patch of teeth 

 often present on front of palatines. First and fourth lateral lines long, 

 usually reaching beyond the middle of soft dorsal and anal ; caudal A^ery 

 broad, rounded posteriorly, even when fin is closed, the membranes covered 

 basally with small scales, those on median membranes in several series; 

 dorsals very deeply notched. Colors usually bright, but varying through 

 green, brown, and bright red, usually dark green with large round red 

 spots, but extremely variable and sometimes finely mottled. Bering 



* Dr. Jordan has the following notes on this species : 



"Two specimens from Petropaulski ; 1 young example from Unalaska. This species 

 seems much less abundant along the shores of Bering Sea than 3. octogrammus {ordina- 

 tus). The Petropaulski specimens give the following data: Dorsal XXII, 21 ; XXIII, 20; 

 aual 23, 24 ; pectoral 20. Cheek scaled above md behind the suborbital stay, naked in 

 front of and including the .stay, except for a small patch of scales immediately below the 

 stay, present in 1 specuuen. Interopercle, subopercle, and opercle naked, except for a small 

 patch of scales on upper partof the latter. Upper lateral line ending under second or fourth 

 epine in 1 specimen, under tenth or twelfth spine in tin- otlur: tlie fourth extends 

 barely to base of centrals in 1 specimen, to opposite end of basal lifth ol' ventrals in the other. 

 There are 7, 8, or 9 scales in an oblique series between second and tliird lines, counted near 

 middle of body. The lowermost line forks at a point slightly nearer base than tip of ven- 

 trals, its distance from ventrals less than J its distance from vent. Ventrals pointed, 

 extending beyond pectorals and more than halfway to front of anal. The caudal fin is 

 strongly emarginate when closed, becoming truncate when spread. It is scaled on basal 

 half only. Color as usual in the species, the light spots on sides numerous, about as large as 

 pupil; fins bright reddish or orange, especially ou basal half."
