A single specimen, 4 inches long, from Calayan. 'The back and sides are sparsely punctulated with 
minute specks. The spinous dorsal has a single row of opaque wedge-shaped white blotches. 
A reexamination of the cotypes of Holocentrus gracilispinis, 18 in number, and ranging in size from 
2 to 5.50 inches, seems to bear out Doctor Giinther’s view of the relations of part of the nominal species 
in thissynonomy. The smaller specimens which are least faded are profusely covered with coffee-grain- 
like specks, like the specimens obtained by Jordan & Kellogg in Samoa, and the spinous dorsal has a 
series of conspicuous dusky blotches, above each of which is a diffused spot of opaque white. In more 
faded young specimens the coarser coffee-grainlike specks and the dark markings on the spinous dorsal 
have nearly disappeared. In specimens over 4 inches long, all of which are more or less faded, the side 
flecks and punctulations have almost completely disappeared in the largest, in which also the dark 
spots on the spinous dorsal are wanting. In one of these, 5 inches long, the opaque white blotches of the 
spinous dorsal, which take the place of the black and white spots of the young, form two series on the 
anterior part of the fin, as stated by Cuvier in the original description of H. lacteoguttatum. The Holo- 
centrum argenteum of Cuvier & Valenciennes and of Quoy & Gaimard, described as without spots on the 
spinous dorsal, is doubtless not distinct from the present species, and has been so regarded by Doctor Klun- 
zinger, who examined the types. The specimens recorded by Doctor Klunzinger from the Red Sea under 
the name H. argentewm had a row of opaque white spots on the spinous dorsal. The figure of H. argenteum 
by Quoy & Gaimard, in slight disagreement with their description, shows an opaquish blotch behind each 
dorsal spine. 
68. Holocentrus ruber Forskal. Swgac. 
One specimen, 5 inches long, from Cagayancillo, two from Cuyo, 2 inches, and one from Calayan, 
1.50 inches. Side stripes black; outer soft ray of ventral blackish from base to tip. In life reddish 
with darker stripes; belly speckled; pectoral rays dark yellow; a dark blotch in upper portion of each 
spinous dorsal membrane. These specimens belong to the highly colored (coral reef) type called Holo- 
centrus praslin. 
A single specimen from Cuyo, 3 inches long, has the color much paler than in H. praslin. The 
ventrals are broadly tipped with blackish, not with the outer ray dusky and the rest pale, as in the 
form called praslin. This specimen evidently belongs to the form called Holocentrus ruber by authors. 
69. Holocentrus microstomus Giinther. Sugac. 
One example, 4.50 inches long, from Cagayancillo. General color in life crimson; several longitu- 
dinal lines of pure white on sides; belly and chin white; flags of first dorsal crimson in membranes; a 
deeper colored blotch on first and second membrane; pectoral, ventral, caudal, and anal crimson. 
70. Holocentrus sammara (Forskal). Sugac. 
One specimen from Cagayancillo, 5 inches long. In lite chiefly metallic silvery; scales with dusky 
spots forming nine longitudinal lines; head dark on top; opercle rosy; preopercle silvery; pectoral 
rosy; ventral white; first dorsal with deep red-brown spots in the membranes, and with an opaque (white ?) 
spot above and below; first three membranes of spinous dorsal each with a spot of dark crimson; second 
dorsal with first three rays and membranes dark red, the others yellow; caudal dark reddish brown 
above and below; middle yellow; third spine and first ray of anal red, the rest yellow.
