FISHES OF HAWAIIAN ISLANDS. 
341 
tip of ventral, its length 1.4 in head (in the type there are 12 rays on right side and 9 on left, which is 
doubtless a deformity); distal border convex (on left side); origins of dorsal, pectorals, and ventral 
about in same vertical. 
Scales large, firm, those on breast not reduced, those at base of dorsal hardly forming sheath, no 
sheath at base of anal; large scales on upper and posterior portion of the operele, 1 row of about 
7 scales below and behind the edge, remainder of head naked; lateral line complete, portion to the 
head parallel to the dorsal outline, straight portion beginning below base of fourth from last soft dorsal 
ray; 2 or 3 supernumerary scales, with tubes, extending from upper portion on the row just above 
straight portion, tubes much branched, the branching covering well the exposed portion of the 
scale; teeth in anterior portion of jaws distinct, pointed, imbricated in several series; 2 posterior 
canines; lateral teeth in upper jaw small, distinct, in a single series; lateral teeth in lower jaw large, in 
a single series; 2 conical teeth within the outer teeth at symphysis of upper jaw, other small teeth 
within the outer ones on sides of upper jaw. 
Color in alcohol, head and body a uniform brown with some indications of dots of lighter on 
some of the scales, and a wide margin on the posterior border, each scale showing paler than the base; 
dorsal fin brown with faint traces of mottlings, no dark spot on anterior portion or darker margin; 
anal darker brown with less evident mottlings, and no darker margin; caudal much paler than body, 
upper and distal edges brown; ventral with indications of brown clouding; pectoral pale, without 
markings except that the base is dark brown; no markings on head except that top of head and 
isthmus are darker than sides of head. Description is based on a single specimen 15 inches long to tip 
of caudal, obtained at Honolulu by the Albatross, 1896. 
This species appears to be similar to Scarus spinidens ( Callyodon wdigiensis Cuvier & Valenciennes, 
Hist. Nat. Poiss., Vol. XIV), a small species first described, very imperfectly, from the island of 
Waigiu. A specimen from this island has been identified by Bleeker as Cuvier & Valenciennes’s 
species, which he designates as Callyodon spinidens and of which he gives a full description and a 
figure. The present species differs from Bleeker’ s description in the dorsal outline, in its greater depth, 
much smaller eye, longer snout, and much longer ventral, in not having scales on the lower limb of the 
operele and in having the base of the anal dark. Dr. Bleeker had many (72) specimens, and found 
C. spinidens of a limited range in distribution. 
Honolulu; only the type known. 
Calotomus cyclurus Jenkins, Bull. U. S. Fish Comm., XXII, 1902 (Sept. 23, 1903), 465, fig. 24, Honolulu (Type, No. 50849, U. S. 
N. M. Coll. Albatross, 1896). 
270. Calotomus sandvicensis (Cuvier & Valenciennes). “ Ponuhunuhn.” 
Head 3.3 in length; depth 2.5; eye 6.4 in head; snout 2.5; preorbital 4; interorbital 4; D. x, 11; 
A. ii, 9; scales 2-24-5. 
Body short, deep and compressed; dorsal and ventral outlines about equally convex, dorsal rising 
in a gentle curve from tip of snout to origin of dorsal fin, then in a long lower curve to base of caudal 
peduncle; head rather short; snout short, bluntly conic; mouth small, in axis of body, the lower jaw 
slightly included, each jaw provided anteriorly with about 3 irregular series of distinct imbricated 
incisor-like teeth; upper jaw with 2 strong backwardly directed canines on the side, lower jaw with 
a single series of small close-set teeth on the side; eye small, high up, the preorbital rather wide; 
interorbital high, convex; caudal peduncle moderately deep, about 2 in head. 
Scales very large and thin; lateral line with a slight jog under base of last dorsal ray, the pores 
numerously branched; a single row of 4 scales on cheek, and 4 scales on anterior portion of operele. 
Dorsal spines soft and flexible, their length scarcely equaling that of snout, last dorsal rays some- 
what elevated, their length nearly half that of head'; anal similar to soft dorsal, its rays equally long; 
caudal somewhat lunate, the upper lobe usually the longer, about 1.2 in head; ventrals short, reaching 
half way to origin of anal; pectoral broad, the free edge convex, the upper rays about 1.4 in head. 
Description based chiefly upon specimen No. 05646. 
Color in life (No. 03368), mottled gray and brown, scarcely reddish below; spinous dorsal with a 
black spot on membrane between first and second spines, a faint reddish stripe along base, and another 
along edge of dorsal fin; soft dorsal with pale reticulations around faint dark spots; caudal still more 
faintly mottled and with white edge, a blackish line before it; anal mottled brown with reddish shade 
at base and tip; pectoral yellowish, the base dusky; ventrals mottled dusky gray.
