REVIEW OF THE SERRANID^.

broad, broader than in any other of the Serranidce, scaly, its width scarcely less than that of the 
preorbital; teeth A'ery small, in villiform bands; no canines; the outer teeth above very slightly 
enlarged; preopercle snbrectangnlar, the perpendicular limb straight, vertical and finely ser- 
rate; angle with larger, radiating teeth; about ten small sharp teeth oii the lower limb directed 
downward, the anterior directed slightly forward; top of head, maxillary, inaudible, opercular 
bones, all parts of the head except the eye aud lips closely covered with small rough scales, much 
as in the genus Priacanthus ; scales on opercle small, like those on the cheeks; gill-rakers very 
long, about x+20, the longest If in eye; opercular spines very weak; lateral line bent upward 
anteriorly, but not running high, the scales above it smaller than those below ; dorsal and anal 
fins naked, but witd a scaly sheath at base; dorsal spines low, the fifth highest, 3^ in head ; soft 
dorsal rays few and rather long, their height not twice that of last spine, 3 in head; anal tin 
low, the sjtines strong, graduated; second anal spine 4 in head; caudal Innate, with rounded 
lobes; pectoral pointed, rather short, 1| in head. Color dusky-silvery, the lius blackish ; lateral 
line black, conspicuous, much as in Centropomm undeoimalis. Head, 2f in length ; depth, 2f. D. 
X, 11 ; A. Ill, 9. Scales, 66 (pores) ; 70 rows above lateral line, 100 below ; 18 between first dor- 
sal spine and lateral line Macrophthalmos, 12.

165, 1859; (copied). Kner, Neiie Fische aus Mus unn Godeft’roy, 1867, 3, plate. (Iquique). 
Hemilutjanus (macrophthahnus) Bleeker, Systema Percaruui Revisum, 1875, 277 (generic diagnosis). 
Habitat. — Coasts of Peru aud Chili. 
Etymology. — Maxpoq., large; eye. 
We have examined specimens of this species in the museum at Cambridge from 
Peru aud from Caldera, Chili. The specimen from which our account is taken (21716 
M. C. Z.) is from the coast of Peru; E. G. Squire. It is about 11 inches in length. 
The species is well represented in the figure published by Dr. Kner. 
13. HEMILUTJANUS PAYTENSIS. 
Pleotropoma paytensis Lesson, “Voyage de la Coquille, Zool. 233, 1828” (Payta.); Giinther, I, 165, 
1859. (Copied). 
Habitat. — Coast of Peru. 
Etymology . — Named from Payta, where it was first found. 
We know nothing of this species except what is contained in the few words quoted 
by Dr. Gunther from Lesson. It may not belong to Hemilutjanus .i though, so far as it 
goes, the description accords with this genus. Possibly it is simply the young of H. 
macrophthalmos. 
Genus V.— GONIOPLECTEUS. 
Gonioplectrus Gill, Proc. Ac. Nat. Sci., Phila., 1862, 236, 237 (Jiispanum). 
Type. — Plectropoma hispanum Cuv. and Val. 
Etymology. — Pcovia, angle; nXrjxrpov, spur. 
This well-marked genus contains a single species allied to Plectropoma and Alphes- 
tes, but with a stronger opercular armature than is found in any other genus. Accord- 
ing to Poey, the skull “shows a great affinity with Hypoplectrus. Thus it is rounded 
above, the supraoccipital crest is below the level of the froutals; the other crests are 
low.” In some respects Gonioplectrus resembles Anthias.
