NO. 1289. FISHES FROM FORMOSA— JORDAN AND EVERMANN. 3f)5 



gill-opening- large, the branchiostegal membrane narrowly free over 

 the isthmus; gillrakers 1 + 18, 3 of which are developed on the 

 upper part of the ceratobranchial, all the others very short, rounded, 

 and finely villous; pseudobranchi.t^ well developed; branohiostegals 

 rather large, 8 in number; intestine short, of several turns; pyloric 

 caH^a 3, short; peritoneum pale or silvery. Scales small, thin, elongate 

 and c3'cloid, very small upon the vertical fins, and upon the pectoral, 

 the latter completely covered. Origin of the dorsal before that of the 

 pectoral, the fin of uniform height and confiuent with the caudal, which 

 is pointed; origin of the anal nuich nearer the tip of the snout than 

 base of caudal and similar to dorsal; pectorals broad, rounded, and a 

 little less than halfway to origin of anal; ventrals of two filaments, 

 one much longer than the other and ensheathed in a mem])rane for 

 half the length of the longer; ventrals inserted slightly nearer posterior 

 margin of eyo, than edge of opercle; lateral line superior and not 

 particularly distinct. 



Color in alcohol, more or less uniform ])rown, the edges of the 

 vertical fins and pectorals blackish. Length 10 inches. 



This description from a female from Formosa, No. 359, F. I., 

 returned to the Imperial Fisheries Institute. 



Family PLELTRONECTID^. 



179. PSEUDORHOMBUS OLIGODON (Bleeker). 



This specjes difi'ers from Parol ichtkys arsins ( = /'*. russelll) in hav- 

 ing the scales on the blind side ctenoid, like those on the left side. 



The genus Pseudorhomhus {malayanus; russelU) may be recognized 

 as distinct from Pared ichthys^ being characterized by the presence of an 

 accessory branch to the lateral line running from the upper edge of 

 the gill-opening to the nape. The American species and the Japa- 

 nese species oZivacv^^s' belong to Paralicldliys. The East Indian .species 

 all seem to belong to Pseudorhomhus. 



The species of this type, described by Richardson ^ from drawings 

 made at Canton, are probably unrecognizable from the descriptions.
