Island to Monterey ; not rare; becoming more common northward; a very 

 showy species, extremely variable in color. Dr. Gilbert observes that the 

 species is abundant in Unalaska. He states that the patch of palatine 

 teeth is an unreliable character, as 5 specimens out of the 9 examined do 

 not exhibit it. The species is well distinguished by the depth of the dor- 

 sal notch, the comparative smoothness of the scales, and the large size of 

 the supraocular tiap. The upper line of pores extends well back under 

 base of soft dorsal, and the fourth line is unbranched. The sides of the 

 head are scaled, excepting the region over suborbital stay, the snout, and 

 the interopercle. {superciliosus, pertaining to the eyebrow.)

2262. HEXAGR.4MM0S LAGOCEPHALUS (Pallas). 



Head 3| to 4 in length; depth 3.| to 3f : eye small, about 5?, in head. 

 D. XX to XXIII, 22 to 24; A. 22 to 24; P. 20 to 21. Outer row of teeth 

 enlarged in both upper and lower jaws. Teeth on vomer and front of pal- 

 atines. Maxillary extending to below middle of eye in adults, 2J^ in head 

 (2|- in young). A small flap above eye, fringed along the margin: no 

 tentacles on nape. Fins high, the spinous dorsal deeply notched, the last 

 spine somewhat longer than the one f»receding; in the adult the fifth 

 spine is the longest, nearly ^ length of head, the third and fourth spines 

 nearly equal to the fifth; from the fifth the spines gradually diminish in 

 height to near the end of the fin, when they become rapidly shortened to 



* The following is Dr. Beau's (lescTii)tion of H. scaber: 



"Head 4* without opertuhir tlaj); d.iitli 4i. D. XXI, 24; A. 24; lateral line about 107; 

 transverse'about 50; eye 3 in lua(l.ti|ual to interorbital. Body oblong, moderately com- 

 pressed; upper outline of head convex, but with a slight frontal depression; leastheightof 

 tail equals A of head; jaws equal; the maxillary not quite extending to anterior margin of 

 pupil; teetii on jaws and vomer, none on palatines; a tentacle over each eye. Origin of 

 spinous dorsal directly over base of pectoral, the longest spine 11 in body ; the'longest'dorsal 

 ray eq u.tI to iiostorbital part of head ; dorsals deeply notched ; base of .-inal 3 in body ; vent 

 equidistant between tip of snout and base of caudal fin: caudal decidedly forked; pecto- 

 rals iiot(|uiti- rtaching vent, the length equal to head with opercle flap; distance of ven- 

 trals fiDiii snout more th^ twice length of ventrals, which is 7 in body; 6 lateral lines on 

 each side, the npiiermost meeting its fellow on the opposite side in front of the dorsal, and 

 continui-d tnrward on the nape in a single short line; it runs backward close to the base of 

 dors;d and ends ;it beginning of last third of soft dorsal ; second beginning at nape, ^ as far 

 from the upiierniost as it is from the third, and extending to the caudal ; the third beginning 

 at the upper end of the mil opening and ending on the caudal ; the fourth a little above the 

 pectoral, curving vei-y slightly downward and dis.appearing about the middle of the body, 

 not so well developed as the rest ; the lifth originates close under the pectoral, near the gill 

 opening, passes above the ventral and on the lower part of the side of the body, ending 

 at about the beginning of the last third of anal; the sixth meets its fellow of the oppo- 

 site side a little behind the ventral base, and extends forward in a single line, and runs 

 backward close to the base of the anal fin, ending on the caudal; scales everywhere very 

 rough. Light brown, silvery below; each dorsal with 3 dark blotches, smaller than eye, 

 not reaching base of tin; pectorals, ventrals, and anal immaculate. Coast of Alaska; 

 known from young specimens only, the largest 3 inches long.'' (Bean). We have exam- 

 ined these specimens and find them, beyond question, the young of H. supereiliosus.
