DESCRIPTIONS OF A NEW GENUS AND TWO NEW SPECIES OF FISHES 
FROM THE HAWAIIAN ISLANDS. 
By DAVID STARR JORDAN and BARTON WARREN EVERMANN. 
Since the publication of our recent paper® on new species of fishes from the 
Hawaiian Islands, further studies of our large collections have resulted in the dis- 
covery of an interesting new species of Tropidichthys and a remarkable new genus 
of Scorpamida}. These are described in the present paper. Illustrations of both 
species will be given in our final report. 
Tropidichthys psegma Jordan & Everinann, new species. 
Head 3 in length; depth 2; eye 4.5 in head; snout 1.5; interorbital 2.3; D. 11 ; A. 11; 0. 8; P. 16. 
Body short, stout, moderately compressed; snout long, conic; anterior dorsal profile rising evenly to 
region above gill-opening, at which point the body is deepest; interorbital flat; gill-opening nearly ver- 
tical, short, its length less than diameter of eye; mouth low, below axis of body; teeth strong, convex, 
cutting edge sharp; eye small, supraorbital rim not prominent; caudal peduncle deep, its least depth 
about 2 in head, its least width, 4 in its least depth; length of caudal peduncle from dorsal fin to base 
of caudal tin 1.3 in head; from base of anal tin 2 in head; dorsal prominence equally distant between 
tip of snout and posterior base of caudal; base of dorsal 1.5 in height of fin, which latter is 2 in head ; anal 
similar to dorsal, its edge rounded; caudal truncate, or very slightly convex, 1.2 in head; pectoral 
broad, its base 2.6 in head, free edge oblique, posterior rays 1.5 in anterior ones; body mostly smooth; 
interorbital space and snout above and on side with small prickles; belly with a few prickles; a scat- 
tered patch also on side above pectoral. 
Color in alcohol, dark brown above, paler below ; 3 or 4 short black lines running forward from 
orbit, and same number backward; lower part of side, especially posteriorly, and lower part of 
caudal peduncle, with small roundish black spots; snout and interorbital space crossed by about 12 
narrow black lines, these extending down on side of snout; side of snout with 3 or 4 narrow black 
lines from chin toward eye, separated by paler lines; posterior to these small irregular black spots 
covering entire cheek, dotted over with fine white specks; ends of spines, pectoral, dorsal, and anal 
pale whitish, their bases largely brownish black; caudal dark brownish or black. 
This species is known to us only from the type, No. 50885, U. S. N. M. (field No. 2561) 3.75 inches 
long, obtained by us at Honolulu in 1901. 
We have compared this specimen with examples of T. coronaius Vaillant & Sauvage, obtained by 
the Albatross in 1902, and find them quite distinct. 
IRACUNDUS Jordan & Everinann, new genus. 
Iracundus Jordan & Ever maun, new genus of Scorpxnidic ( signifer ). 
Allied to TIdicolenus and Pontinus. Body rather elongate, compressed, covered with small, weakly 
ctenoid scales; fins not scaly; head not depressed; formed as in Sebastodes, the spines moderately 
developed; head and body with dermal flaps; teeth on jaws and vomer, none on palatines; dorsal fin 
deeply divided, the spines 11 in number, the fourth much elongate; pectoral rays undivided; anal 
rays in, 5; ventral rays i, 5; caudal rounded; vent at base of first anal spine; air bladder obsolete.
