Mouth large: upper jaw 29.8-35.8% HL (30.2% HL); 
lower jaw 40.5-48.0% HL (41.7% HL). Orbit moderate- 
ly large, 11.5-18.8% HL (14.7% HL). Gill rakers 22-30 
(28), long, 8.2-12.4% HL (9.5% HL), slender, 4-6 (4) on 
upper part of arch, 18-26 (24) on lower part. Pseudo- 
branchs 8-19 (10). 
Pored lateral-line scales 114-170 (126). Scales be- 
low lateral line situated along 139-193 (150) oblique 
dermal plicae. 
Dorsal-fin rays 56-66 (58). Anal-fin rays 25-33 (27), 
7—13 (9) pterygiophores anterior to first caudal ver- 
tebrae. Pectoral-fin rays 13-16 (14), rays 3-7 (3) pig- 
mented. Total vertebrae 65-73 (69), precaudal verte- 
brae 40-47 (44), caudal vertebrae 21-27 (25). 
Distribution 
On the basis of material examined, we determined that 
Ammodytes personatus ranges from California to the 
Gulf of Alaska, west to Attu Island in the Aleutian Is- 
lands, and north to Norton Sound in the northeastern 
Bering Sea (Fig. 1). In the eastern Bering Sea, its range 
overlaps with that of A. hexapterus in Norton Sound, 
the Pribilof Islands, Kuskokwim Bay, and Unimak Pass 
(Fig. 1). Ammodytes personatus (as A. hexapterus) has 
been reported also from as far south as Balboa Island 
in Southern California (Love et al., 2005). Unpublished 
sequence data of Turanov and Kartavtsev (2014) sug- 
gest that A personatus may range from Bering Island
