112 "endeavour" scientific results. 



Body very compressed and elevated, forming a sharp angle 

 at the origin of the dorsal fin. The profile is straight from 

 the upper lip to above the middle of the eye, thence rising 

 rapidly and forming a hump on the nape. Lower profile 

 slightly convex from the lower jaw to the ventral spine ; 

 abdominal margin oblique, the origin of the anal being below 

 the level of that of the ventral. 



Head closely covered with small ctenoid scales, which 

 extend onto the maxilla and lower jaw, leaving only the lips 

 bare. Sides of occiput with radiating, bony ridges, which 

 extend forward above the eye to before the nostrils. Occipital 

 crest with similar denticulated ridges extending up the 

 anterior margin of the hump. Preorbital with the anterior 

 margin denticulate, and a series of radiating ridges. Angle 

 of preoperculum broadly rounded, serrated, and bearing 

 curved bony ridges ; an inner preopercular margin forming 

 a right angle below and finely denticulated. Operculum un- 

 armed, with a shallow excavation on the upper posterior 

 margin. Maxilla small, but little oblique, not reaching back- 

 ward to the verticle of the anterior nostril. Nostrils placed 

 in front of the upper portion of the eye, the anterior in a low 

 tube, the posterior an open pore. Scales in about seven rows 

 on the cheeks. 



Body closely covered with strongly ctenoid scales, which 

 are very coarse on the ventral surface. They extend up the 

 anterior margin of each spine of the fins, and also along the 

 lower surfaces of the ventral rays, where they are particularly 

 spiny. Small, but similar, scales cover the lower third of the 

 soft dorsal and anal fins. Lateral line forming a high arch 

 below the anterior dorsal spines, thence running obliquely 

 downward to the middle of the side and extending along the 

 caudal peduncle. About fifty-eight scales between the oper- 

 culum and the hypural. 



Anterior spines of each fin coarsely striated. Third dorsal 

 spine longest and strongest, the remainder decreasing regu- 

 larly backwards ; the tips of all are broken off or damaged. 

 Anterior dorsal rays higher than the posterior spines, the 

 others becoming regularly lower backwards. Anal fins 

 similar in form to the dorsal. Pectoral pointed, the upper 

 rays longest. Ventral spine long and strong, reaching back- 

 wards to the first anal ray. Caudal slightly emarginate, the 

 upper rays a little longer than the lower ones. 



Colour. — Generally pink in life, becoming pinkish-grey
