substance of the scales. In both species there may be a rather irregular trans- 
verse radial line, crossing the middle of the scales but not reaching the extreme 
sides. In both, the laterobasal angles are practically right angles. The 
dimensions are — L. splendens, length 13, breadth 11^4 mm.; L. waigiensis, 
length 11, breadth 10 mm. 
HOLOCENTRIDiE. 
Holocentrus angustifrons Ogilby, from Queensland, has scales about 
5y 2 mm. long and 8 broad, the apical margin with strong straight teeth ; the 
sides sloping to the very broad base, the laterobasal angles therefore extremely 
prominent; the straight base with about four lobules, the ends of longitudinal 
ribs, near the middle. Circuli very tine, failing apically; region below the 
nucleus more or less pustulose. Except that the laterobasal corners project 
more, these scales agree with those of H. diadema Lacep., from Hawaii. The 
scales of the species of Holocentrus are on the whole very uniform. 
PEMPIIERIDiE. 
Pempheris multiradiatus Klunzinger. Scales of three sorts; it is noted 
on the label, * 4 breast scales ctenoid.’ ’ Scales broader than long, with a diameter 
of 3 to 4 mm. Normal cycloid scales broadly rounded apically, with a nearly 
central nucleus from which proceed, in a radiating manner, about five very 
distinct basal radii; basal margin deeply scalloped; laterobasal angles obtuse; 
basal half of scale with fine circuli, but these are absent from the apical field, 
which exhibits only growth lines. Laieral line scales are broader, and are 
without the basal radii and basal scallops; the basal margin is convex in the 
middle and concave sublaterally. The lateral line canal has a very broad bilobed 
appendage. The ctenoid breast scales are very different from the others, 
quadrate, with straight sides, but broader than long, the apical margin with 
numerous strong straight teeth. The basal radii and scallops are as in the first 
type of scale described. There is no ctenoid patch; the marginal teeth are 
exactly like those of Holocentrus. 
I have scales of Pempheris (f otaitensis) from the Red Sea, which 
resemble the normal cycloid type described above, but are considerably broader, 
with the circuli continuous across the apical field. 
Neopempheris ramsayi Macleav. Scales apparently all ctenoid, with a 
very well developed ctenoid patch. Scales about 3 mm. diameter, somewhat 
broader than long, subquadrate, nucleus a little above the middle; four or five 
very strong basal radii or folds, and basal margin very strongly scalloped; 
circuii very fine; ctenoid structure consisting of rows of elongate teeth. The 
apical teeth are much as in Mullus, but their bases are broadened, and the whole 
ctenoid area is confused, not beautifully distinct in all its details as in Mullida?.
