dorsal and anal prolonged behind, and the preoperculum strongly 
toothed. The Scolopsides , the second suborbital has a spine behind, 
crossing under the orbit the one arising from the front of the third. 
The Latilli have a nearly vertical profile and an elongated body. The 
Macquaries, on the other hand, have a cavernose head and toothless jaw. 
Others have the lateral lines interrupted under the end of the dorsal fins. 
Some of these have the preoperculum toothed, as the Amphiprions, 
which has all the other processes of the operculum toothed, and the 
teeth in a single row. The Premnades have the teeth like the former, 
and the suborbital bones with a spine. The Pomacentres and the 
Dascyli have the other bones of the operculum simple, the former 
having a single series of teeth, and the latter numerous small velvet¬ 
like ones. The remaining genera have no teeth on the operculum. 
The Glyphisodons and the Hetroples have only a single row of teeth, 
the former having only two or three, and the latter many spines to the 
anal fin. The Heliases have numerous small velvet-like teeth. 
The Sparoid Fishes (Sparidze,) are very like the former in form 
and appearance, but their opercular bones are not spinous or toothed, 
the palate is toothless, and the mouth is not protractile. Some have 
only velvet-like teeth, the outer row being rather the largest, as 
Cantherus. Others have conical or tubercular teeth intermixed with 
the others; Lethrinus is peculiar for having naked cheeks without any 
of the scales usually found on the other genera, as the Sarges ( Sargus ), 
Charax. Chrysophris, Pagrus, Pagellus , Dentex , and Pentapus. The 
Smaris have a very protractile mouth, and the Ccesice only differ in the 
base of the dorsal being surrounded with some fine scales. The 
Poops and the Oblades have a single row of flat crenulated teeth in 
front, the latter having velvet-like teeth behind them, which are wanting 
in the former. The Scathari have only a single row of entire flat 
teeth, and the Crenidens have two rows of flat notched teeth, and others 
within them. These four latter genera have no rounded grinders. 
The family of Labroid fish, (L abridge,) so called from the large 
size of the double fleshy lips which cover their teeth, have the general 
form of the Perches; the body is oblong, covered with large cycloid scales, 
and has only a single dorsal fin, which is spinous in front, and furnished 
with membranaceous appendages. The jaws are armed with large 
teeth; their colours are generally exceedingly brilliant, and from usually 
living on rocky shores they are commonly called Rock Fish. Some 
are oblong, with double lips and a shelving forehead; their palatine teeth 
are large and pavement-like, as Labrus , which has a nearly straight 
lateral line. The Cheilinus has the lateral line interrupted near the 
end of the dorsal. The Lachnolaimus has the front ray of the dorsal 
very long and flexible. The Jules have the head smooth without scales, 
and the lateral strongly curved behind. The Anampses differ from the 
former in their mouth being produced and only two flat teeth in the 
palate. The Crenilabrus are peculiar for having the edge of the pre¬ 
operculum toothed. The Coricus only differs from them in having the 
mouth protractile, and the Epibulus has the jaw still more protractile; 
the lateral line is interrupted. The Clepticus has a short cylindrical 
mouth, and the Gomphoses, a very long one in the shape of a tube. 
The Dolphins ( Xirichthys ) differ from the Labri in the forehead being
