JORDAN AND METZ: FISHES KNOWN FROM THE WATERS OF KOREA 29 



echinogaster; and D. 40, A. 38 in Stromateoides cinereus. The name echinogaster 

 refers to the spinules in the oesophagus, common to all stromateoid fishes. 



Description taken from eight specimens, 4.5 to 5.5 inches in total length, 

 collected at Chinnampo, Korea: 



D. 46; A. 43; depth 1.4; head 4.5; eye 3.33; snout 4; interorbital 2.4; 

 pectoral 2.6 in body-length; depth of caudal peduncle 2.66 in head; longest 

 dorsal ray 3.5 in body. Body rhombic, very deep and compressed, deepest 

 under origin of dorsal; nape high; profile of head very steep; snout very blunt, 

 rounded, projecting beyond mouth; eye rather large, median, above level of 

 mouth; giU-openings lateral, vertical or shghtly inclined forward, 1.4 in head; 

 nostrils large, posterior several times as large as anterior, both remote from eye, 

 close together, near tip of snout; lateral line high, irregular in outline, roughly 

 corresponding to dorsal outline. 



First ten dorsal spines modified into anvil-shaped scutes, which are raised 

 above the surface and are sharp at both ends. These are covered with flesh 

 in the adult examples, and are not counted in the number given above for the 

 dorsal and anal rays; first to fourth rays graduated, fourth longest, longer than 

 head; remaining rays growing rapidly shorter to about the fifteenth, which is 

 less than one-third the length of highest, and is about equal to the following 

 ones; anal similar to dorsal, but of fewer rays and scutes; pectoral elongate, 

 slender, reaching half-way to caudal, extending to dorsal notch; caudal deeply 

 notched, the lower lobe usually the longer. 



Color in spirits almost black above the lateral line, especially on top of 

 caudal peduncle; below lateral line the sides become gradually lighter to about 

 the median part, below which they are silvery, except in some specimens where 

 the silver color is rubbed off; posterior part of opercle and margins of vertical 

 fins black; pectoral pale or faint dusky. In most specimens the body and head 

 are irregularly speckled with fine black points. A specimen from Port Arthur, 

 noted by Jordan and Starks as Stromateoides cinereus, has D. 44; A. 42. One 

 from Swatow has D. 44; A. 41. It is quite possible that the two forms cinereus 

 and echinogaster, geminate species, the one northern, the other southern, may be 

 found to intergrade.
