(Stromateoides candidus) (found also rarely in Japan) by its large number of fin- 

 rays. 



The Chinese species, abundant in Canton, is Stromateus argenteus of Bloch, 

 1794, which is the same as Stromateus candidus and Stromateus securifer of 

 Cuvier & Valenciennes, and Stromateus punctatissimus of Schlegel. This species, 

 distinguished by the falcate soft dorsal, with dorsal rays 41, and anal rays 39, 

 should apparently stand as Stromateoides candidus. Stromateus nozawm Ishikawa 

 from the Bay of Tokyo is like Stromateoides argenteus, but differs apparently 

 in the very high dorsal and anal, the lobes when depressed reaching the caudal. 



The following is a description of Stromateoides argenteus (Euphrasen), taken 

 from a specimen 185 mm. long, collected at Fusan, Korea: D. 46; A. 43; depth 

 1.45 in length; head 4.25; eye in head 4.5; snout 3.33. Mouth small, inferior, 

 maxillary reaching to below front of pupil; dorsal beginning half-way between 

 mouth and caudal peduncle; nape high; head sloping to the rounded, blunt 

 snout; back sloping both ways from beginning of dorsal, the profile both anteri- 

 orly and posteriorly being nearly straight, but the former more abruptly slop- 

 ing; dorsal high in front, fourth ray one-third longer than head, sloping abruptly 

 to the fourteenth or fifteenth ray, which is less than one-third the length of 

 the longest ray; anal similar, but with the anterior lobe higher (almost twice 

 head), inserted well behind the origin of the dorsal; pectoral one and one-half 

 times the length of the head, rounded; caudal deeply forked; caudal peduncle 

 short, equal to the length of the last anal rays. 



Color silvery below the lateral line, which runs high, following the outline 

 of the back; upper parts above lateral line dusky, somewhat metallic; vertical 

 fins margined with black. 



We know of no other differences between this species and Stromateoides 

 candidus, except that the latter has the dorsal rays 41 and the anal 39. The 

 two are doubtless "geminate" species, Stromateoides argenteus being from the 

 north and Stromateoides candidus from the south. 



107. Stromateoides echinogaster (Basilewsky) . (Plate V.) 



Chinnampo (No. 4572); Port Arthur (Abbott). 



This species is distinguished from Stromateoides argenteus by the inequality 

 of the lobes of the caudal fin in the adult. In the young the upper lobe is 

 nearly as long as the lower, but with increasing age the lower lobe is one- 

 third to one-half longer than the other. The species is the geminate repre- 

 sentative of Stromateoides cinereus Bloch, of India, differing chiefly in the 

 increased number of fin-rays, being D. 44 to 46, A. 41 to 43 in Stromateoides
