long as the snout, and the figure ^ shows an entirely different fish, 

 as can easily be seen by a comparison with Giinther's figure of the 

 type of Pseudopriacanthus meyeri (Celebes) and the excellent figures 

 of Temminck and Schlegel. It is worthy of note that the present 

 species has been found but once beyond the waters of Japan, namely, 

 in Celebes. Giinther's figure of this specimen corresponds exactly 

 %vith those of Temminck and Schlegel.

3. Family THERAPONID^. 



Body oblong, covered with moderate or small scales. Mouth 

 moderate, with villiform teeth, the outer sometimes enlarged; those 

 on the vomer and palatines deciduous or wanting. Maxillary slip- 

 pmg beneath the preorbital. Branchiostegals 6. Preopercle ser- 

 rated; opercle with one or two strong spines; preorbital entire or 

 serrate. Dorsal fin notched, with 12 or 13 stout spines. Anal spines 

 3, strong. Air bladder divided into two parts by a constriction. 

 Pyloric caeca in moderate number. Carnivorous fishes of the tropical 

 seas, referable to two genera. The family, here provisionally adopted, 

 differs from HsemuHdae in having the aid bladder constricted, and 

 externally in having deciduous teeth' on the vomer, and in having 

 the opercle, as in the Serranidse, armed with spines.

Type. — Holocentrus servus Bloch. 



Tliis genus includes those Theraponidse in which the teeth in the 

 jaws are simple, villiform, or conic. In some species (Eutherapon) 

 the scales are rather large. In some (Pelates, Datnia), the snout is 

 more or less prolonged and the dorsal undivided.
