the longest about equaling snout; soft dorsal somewhat elevated, the longest rays equaling distance 
from tip of snout to pupil; anal similar to soft dorsal; caudal somewhat lunate, the upper lobe the 
longer, about 1.8 in head; ventral short, reaching barely halfway to origin of anal; pectoral broad, 
reaching past tips of centrals, its length 1.3 in head. 
Color in alcohol, dirty yellowish-brown on head and body, marbled with light and darker; side 
above lateral line with a series of about 5 roundish white spots as large as pupil, and numerous smaller, 
irregular, less distinct white spots; side below lateral line with about 10 or 12 large, rounded, white 
spots and numerous small white specks and irregular markings, these especially distinct in pectoral 
region; head with similar white specks and markings; dorsal tin brown, with irregular paler spots; 
membrane between first and second dorsal spines black; soft dorsal with a large brownish- black spot 
at base of last 5 or 6 rays; anal similar to soft dorsal, blotches not so distinct; a series of black blotches 
at bases of rays, the one on last ray larger than others, covering base of last membrane; ventrals 
brownish, dusky at tip, a paler interspace; pectoral dusky, dark at base and in axil, pale on tip. 
The only specimen known is the type, No. 50850, U. 8. N. M. (field No. 1369), 10.5 inches long, 
obtained at Honolulu by me in 1889. 
SCARIDEA Jenkins, new genus. 
Scaridea Jenkins, new genus of Scaridx ( zonarcha ). 
Jaws subequal, the lower just included; dorsal spines pungent; gill-membranes broadly joined to 
the isthmus, not forming a fold; lateral line continuous; 1 row of scales on cheek; teeth white, distinct 
in anterior portion of each jaw, in more than 1 series, irregularly imbricated; lateral teeth in upper 
jaw small, in a single series, outer extremities free, the bases coalesced; lateral teeth in lower jaw 
large, in a single distinct series, crowded together at base; posterior canines present. This genus is 
related to Calotomus in the character of the teeth, but differs from that genus in having stiff, pungent 
spines, in which character it agrees with S. parisoma. From Scarichthys Bleeker it differs in having 
pungent spines, in having the upper lip double for only a portion of its length, and in the distinct teeth. 
From Callyodontichthys Bleeker it is distinguished by the included lower jaw and the distinct teeth in 
upper jaw. Only 2 species known. 
152. Scaridea zonarcha Jenkins, new species.

more convex than the ventral, highest portion of dorsal outline about at third spine; head nearly as 
deep as long; mouth horizontal, about on line'of axis of body; lips thin, the upper double for about
