Genus 208. SEBASTAPISTES Gill. 
Body oblong, somewhat compressed; head large, not much compressed, naked above, and more 
or less uneven, with spinous ridges, often with dermal flaps; preorbital with a stout spine hooked 
downward; mouth large, with bands of villiform teeth on jaws, vomer, and palatines; scales mostly 
ctenoid, of moderate size, often with skinny flaps; dorsal fin with 12 stout spines; anal with 3 spines, 
the second commonly the longest; pectoral large, rounded, the base usually procurrent; some or all of 
the upper rays divided, the lower simple; ventrals inserted behind pectorals; no air-bladder; vertebrae 
10+14=24. Species numerous in the tropical seas; dwarf fishes of singular forms and bright colors, 
very close to Scorpsena, but much smaller in size and with a characteristic spine before the eye. 
Sebastapistes Gill in Streets, a Bull. U. S. Nat. M-us., No. 7, 621877, ( guttata ; includes Scorpsena guttata Girard; S. strongia 
Cuvier & Valenciennes, and Sebastichthys cyanostigma Bleeker). 
a. Body with flap-like dermal appendages. 
b. Middle of upper jaw without cirrus. 
c. Maxillary scarcely reaching beyond posterior edge of eye battieui, p. 455 
cc. Maxillary reaching beyond posterior edge of eye corallicola, p. 4E6 
bb. Middle of upper jaw with cirrus. 
d. Dorsal with 10 and anal with 8 soft rays aspcrella, p. 458 
aa. Body without flap-like dermal appendages. 
e. Supraorbital cirrus absent. 
/. Scales on side of head well developed; scales 42 coniorta, p. 458 
ee. Supraorbital cirrus present; scales 53 galactaema, p. 459 
377. Sebastapistes ballieui (Sauvage). “Poopa’a.” Plate LXXII. 
Head 2.25 in length; depth 2.4; eye 4.25 in head; snout 3.35; interorbital 5.65; maxillary 1.75; 
mandible 1.75; D. hi, 10; A. hi, 5; P. 16; V. i, 5; scales 7-40-18. 
Body moderately elongate, compressed, greatest depth a little before middle of spinous dorsal; 
back slightly elevated; snout rather short, blunt, rounded; mouth large, oblique; mandible slightly 
produced; maxillary reaching a trifle behind posterior edge of orbit, its distal expanded extremity 1.4 
in eye; lips rather thick, fleshy; teeth fine, in broad bands in jaws; vomer with patch of fine teeth; 
tongue rather thick, rounded, little free in front; eye anterior, nearly in first third of head; interor- 
bital space deeply concave; nostrils large, anterior with rather broad fleshy flap, posterior a little the 
« Segregated by Gill “ from their allies by the naked crown and jaws, the spinous armature of the inferior margin of 
the praeorbital, the procurrent bases of the pictoral fins, etc. The genus is intermediate between the sebastoid and scor- 
paenoid genera, and nearly related to Parascorpsena Blkr.” Scorpsena guttata is a true Scorpsena or rather Parascorpxna. 
As this species has not the armed preorbital characteristic of Sebastapistes, it is presumable that the diagnosis of Sebasta- 
pistes rests bn S. strongius.
