ANALYSIS OF SPECIES OF GONIOPLECTRUS. 
a. Body short and deep, with very short, deep tail ; interorbital region narrow, the bones rugose ; snout 
3f in head; maxillary reaching middle of orbit, 2 in head, naked, its supplemental bone well 
developed; preorbital narrow; lower jaw projecting; teeth very small, in narrow, villiform 
bands, the depressible teeth very few ; a stout canine on each side, in front of each jaw, and one 
or two similar canines in middle of side of lower jaw ; eye 4^ in head (exclusive of opercular 
spine); preopercle finely serrate, with a single very large antrorse hook at its angle; opercie 
ending in four s^tines, the second of which is long, straight, compressed and knife-shaped, as 
long as eye; nostrils small, round, separated, the posterior the larger ; suborbital serrate on its 
edge; gill rakers rather long and slender, x -)- 15; scales small, firm, and rough; lateral line 
arched, running high, close to middle of spinous dorsal, and then bent abruptly downward; 
dorsal spines low and stout, the fin notched; soft dorsal short and rather high; longest dorsal 
spine 3 in head ; second anal spine 2|-, very strong, longer than third, the soft rays high and 
rather short, scaly ; pectorals moderate, rounded at tip, longer than ventrals, in head ; caudal 
truncate, its peduncle as deep as long ; color rose-colored, with yellow stripes along head and 
back ; top of head with orange spots ; a pale bar before vent ; caudal fins sometimes with dark 
spots ; fins otherwise plain ; head 21 in length ; depth 2|. D. VIII, 13. A. Ill, 7, scales 70.

Habitat. — West Indian fauna. 
Etymology, — Hispanus, Spanish, its colors resembling those of the Spanish flag. 
This species is known to us from specimens in the museum at Cambridge, sent 
from Cuba by Professor Poey. 
Genus VI.— GILBERTIA. 
Gilbertia Jordan, Genus nova. 
Type. — Pleotropoma semicinctum Cuv. & Val. 
Etymology . — iS’amed for Dr. Charles Henry Gilbert, of the University of Indiana. 
The group of species of which Plectropoma semicinctum is the type seems to us to 
form a genus sufiScieutly distinct from Plectropoma. The latter genus (taking Bodianus 
cyclostomus Lac. { = B. melanoleucus Lac.) as its type,* has a much shorter dorsal fln 
(D., VIII, 11 or 12) and small scales. Both genera have lateral canines in the lower 
jaw. There are no American species in Plectropoma as now restricted. 
Besides the typical species, semicincta, the three following, none of them examined 
by us, appear to belong to Gilbertia : 
Plectropoma nigrorubrum Cuv. & Val. (Australia). 
Plectropoma annulatum Giiuther (locality unknown) and Plectropoma armatum 
Castelnau (=P. huntii Hector), from Australia. 
*Thi8 arrangement accords with the earliest restriction of Plectropoma, that made by Gill in 
1862. Bleeker has since transferred the name Plectropoma to Lates, because of the three species placed 
by Cuvier in Plectropoma, the one standing first in the list was Lates calcarifer. To the genus called 
Plectropoma by Gill he has given the new name of Paracanthislius.
