Described from a specimen 10.75 inches long (No. 05301) taken at Hilo; another smaller was 
obtained by the Albatross at Honolulu. Examples recently seen in aquarium at Waikiki. Beaches a 
weight of 4 or 5 pounds.

Genus 212. SETARCHES Johnson. 
Head and body compressed; head scaleless above, its bones cavernous, flat, between the eyes; only 
1 pair of spines at occiput; no transverse groove at occiput, only small spines or none above orbit; oper- 
cle and preopercle strongly armed with straight long spines. Eye moderate, near, but not touching, 
profile. Mouth terminal, broad, somewhat oblique; maxillary extending to posterior edge of eye, 
much expanded behind. Lower jaw somewhat projecting, the small symphyseal knob received in 
rostral notch. Villiform teeth on jaws, vomer and palatines. Preorbital with 2 or 3 spines. Operele 
scaly. Scales cycloid, moderate. Lateral line a broad, scaleleste groove with skinny (about 27 to 30) 
tubes. No laciniie. Dorsal deeply notched, with 12 spines, its origin in front of pectoral; soft, dorsal 
shorter, the rays few'er than the spines. Anal inserted under end of dorsal, its spines strong, gradu- 
ated. Pectoral broad and bony, with 20 or more rays, of which a considerable number of median ones 
are branched. Branchiostegals 6 or 7. Pyloric appendages few. Deep water. 
The single Hawaiian species ( S . remiger ) of this genus is fully described in Section II.
