FISHERY BULLETIN': VOL. 69, NO. 2 



gresses fi'om about 1/4 length of uppermost 

 single ray to about 1/2 of lowermost ray. 



Upper jaw teeth simple and in two modal 

 sizes. A larger outer row, sometimes mainly 

 uniserial, extends nearly length of each pre- 

 maxillary. Anteriorly, teeth larger yet and band 

 broadens. A medial gap where tooth patches at 

 lower jaw tip meet upper jaw (small papilla 

 in middle of gap) . A smaller inner row of teeth, 

 may also be uniserial, in narrow band over most 

 of premaxillary; it loses uniserial character near 

 large anterior teeth, skirts behind them and con- 

 tinues to medial gap. Teeth of lower jaw simple, 

 uniserial, and similar in size to large teeth in 

 row of upper jaw. Anteriorly, lower jaw teeth 

 are larger and in a tuft that is separated from 

 midline by narrow gap — with jaws shut, from 

 1/2 to all of each tuft is visible. Vomerine teeth 

 small, in broad V-shaped patch, and sometimes 

 slightly enlarged to suggest a tuft at ajjex of 

 patch. Palatine teeth small, uniserial except 

 anteriorly where row broadens. Gill rakers 

 slender and pointed, one at bend of arch steps 

 1.6-2.2 (mode 1.8) into orbit. A small slit be- 

 hind last gill arch. 



A large prenarial pore on side of snout in 

 angle formed by premaxillary process and pre- 

 maxilla. A larger subnarial pore on flat shelf 

 immediately below nares — outer margin of shelf 

 formed by part of dorsal margin of lacrimal 

 bone. Smaller pores occur singly above nares 

 and below nasal spine. Two large pores on 

 ventral surface of lacrimal bone — one slightly 

 anterior to vertical through subnarial pore and 

 another slightly posterior to this vertical and 

 beneath anterior blunt projection on ventral 

 surface of lacrimal bone. Four prominent pores 

 on each mandible — first in or near fold formed 

 by symphyseal knob and remaining three in a 

 line along ventral surface. 



Suborbital bones continuous around eye; sec- 

 ond (suborbital stay) conforms to Type 1 of 

 Matsubara (1943a: 10-13), i.e. stay tapers to 

 point posteriorly and does not reach i)reopercle. 

 Sensory canal terminates at midlength of stay. 

 Third and fourth suborbitals tubular. Seven 

 branchiostegais, .^'/i on ceratohyal and V/o on 

 epihyal. 



COLOR 



Background color of body (based on Koda- 

 chrome transparencies of seven freshly caught 

 young adult specimens from Davidson Bank, 

 near Unimak Pass, and the Yakutat vicinity) 

 varies from light pink or light purple-pink to 

 deep red, masked with irregular pattern of dark 

 pigmentation that varies between specimens 

 from barely detectable grey through brown to 

 melanistic black. Masking nearly absent on one 

 large individual with red coloration. Some in- 

 dividuals had faded, nearly colorless appear- 

 ance. Pattern of black pigmentation on sides 

 below dorsal fin basically three large irregular 

 areas extending from midline to or onto fin. 

 One pigmented area beneath middle and another 

 beneath last 1/4 of spinous dorsal fin — first 

 slightly interrupted by narrow light area where 

 it crosses lateral line; second broadly interrupt- 

 ed by light band reminiscent of band along lat- 

 eral line of S. proriger. Third large pigmented 

 area beneath soft dorsal fin forms irregular 

 circle with light spot at center, continues onto 

 lower 1/2 of soft dorsal fin, interrupted near 

 lower border by broad light-colored band along 

 lateral line. Band extends over posterior 2/3 

 of body. Small pigmented area on dorsal caudal 

 peduncle extends downward to but not across 

 lateral line and forms anterior boundary of 

 I)upil-sized lighter spot on dorsal shoulder of 

 caudal fin. Head with diffuse brown to black 

 shading from symphyseal knob and nearby por- 

 tions of lower jaw to nape; on snout, shaded 

 area extends ventrally to a line through 7 o'clock 

 position on eye. Behind eye, dark shading ex- 

 tends ventrally to about 5 o'clock position and 

 posteriorly over preopercle. Nape dusky to a 

 line between 1 o'clock position of eye and an- 

 terior lateral line. Opercle with two broad pig- 

 mented bands whose converging axes meet when 

 projected into lower hemisjihere of eye. Ujtper 

 band includes both opercular spines; lower ex- 

 tends toward pectoral base and includes upper 

 two preopercular spines. Lower band aligiis 

 generally with irregular pigmented areas on 

 upper 1 2 of jjcctoral base. On cheek of most 

 specimens a short pigmented streak extends 

 posteriorly and slightly downward from ujiper
