the same ages. Giinther's L. Tiaematoyterus was a much larger fish 

 and had a smaller eve, which was contained twdce and a tliird in the 

 snout and was not equal to the interorbital space. Our small speci- 

 men, labeled Lethrinus ricliardsoni, from Formosa, fits Bleeker's 

 description well save for a lesser depth and corroborates his differ- 

 entiating marks, i. e., the molars and the six rows of scales above the 

 lateral line. There appear to be only two specimens of this recorded 

 besides ours and that of Bloch and Schneider. 



There is not much doubt that this is the original Spams chce.ro- 

 rhyncTius of Bloch and Schneider, described from Japan. It is a 

 species with broad body, clouded in color, mth the anterior teeth 

 conic, the posterior molar, the opercles scaly, the cheeks naked.

12. Genus EUTHYOPTEROMA Fowler. 

 Euthyopteroma Fowler, Journ. Acad. Nat. Sci. Phila., 1904, p. 527 (blochii). 



Type. — Dentex hlocTiii 'B\eeker = Sparus japonicus Bloch. 



Body rather elongate, covered with rather large ctenoid scales; 

 about 50 in the lateral line; mouth rather small, the jaws equal; 

 upper jaw with small canine teeth, none in the lower jaw; lateral 

 teeth pointed, no molars; suborbitals unarmed; preopercle coarsely 

 or finely serrulate; cheeks with three series of large scales; top of head 

 scaly; preopercle naked, opercle without spine. Branchiostegals 6; 

 air bladder notched. Dorsal thjs X, 9; anal III, 7. Soft dorsal and 

 anal seal el ess, no sheath of scales at their base. Spines feeble, some- 

 times filamentous; caudal deeply forked, the upper lobe sometimes 

 filamentous. 



Species numerous in the East Indian region, mostly brightly 

 colored, and showing analogies to Aprion and Pristipomoides. The 

 genus is close to the European genus Dentex, differing in the more 

 elongate body and the much larger scales on the cheek. 



We here accept Fowler's division of the genus Nemipterus 

 Swainson = Dentex Bleeker, not of Cuvier ^ = Synagris Giinther. 



In this group the following genera or subgenera may be recognized : 



a'. Lower Jaw as well as upper with distinct canines; dorsal spines low, the mem- 

 branes not notched, none of the spines or rays filamentous. 



Synagris {=Aneinura). 

 a?. Lower jaw without distinct canines. 



b^. Dorsal spines all low, with the membranes not notched, the spines scarcely 

 exserted Euthyopteroma. 



}p. Dorsal spines unequal, the first two (or one) produced in long filaments, the 

 membranes of the others not notched, the other spines scarcely exserted. 



Nemipterus. 



b^. Dorsal spines unequal, the middle ones highest, their membranes deeply 

 notched, so that the tips of the spines are largely free OdontoglypMs. 



• The genus Dentex of Cuvier is based distinctly on Sparus dentex of Linnaeus, a Mediterranean species.
