double oniy a short distance; lower jaw just included; interorbital slightly convex, considerably 
broader than eye; caudal peduncle, least height a little less than half head; dorsal spines fiexible, 
rather high, nearly half head; soft dorsal 2 in head; anal similar, but less high, longest ray 2.3 in 
head; caudal rounded, no rays produced; ventrals 1.5 in head, reaching halfway to base of third 
soft anal ray; pectoral broad, its tip reaching to or slightly past vertical through 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 
deformed); distal border convex (on left side) ; origins of dorsal, pectoral, 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 opercle; 1 row of 
about 7 scales below and behind eye; remainder of head naked; lateral line complete, portion to bend 
parallel to 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 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 outer teeth at symphysis of upper jaw, other small teeth within outer ones at sides of 
upper jaw. 
Fig. 24 . — Calotumus cyclurus Jenkins, new species. Type. 
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 of the posterior border of each scale shows paler than the base; 
dorsal fin brown, with faint traces of mottlings, no dark spot on anterior portion, nor darker margin: 
anal darker brown, with less evident mottlings and no darker margin; caudal much paler than ho ly 
with upper and distal edges brown; ventral with indications of brown clouding; pectoral pale without 
marking, except that the base is dark brown ; no marking shown on head, except that top of head and 
the isthmus are darker than its sides. 
This description is based on a single specimen, 14 inches in length to tip of caudal, obtained at 
Honolulu by the Albatross in 1896. This species appears to be similar to Callyodon waigiensis ( Scarus 
spinidens Cuvier & Valenciennes, Hist. Nat. Poiss., vol. 14), a small species, first described very 
imperfectly from the island of Waigiou. A fish from this island has been identified by Bleeker as 
Cuvier & Valenciennes’s species, which he designates as C. spiniclens, and of which he gives a full 
description and a figure. My specimen differs from Bleeker’s description in the dorsal outline, in 
having a greater depth, a much smaller eye, and longer snout, in much longer ventral, in not having 
scales on the lower limb of the opercle, 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. (Type, No. 50849,
