REPORT ON THE SHORE FISHES. 73 



japonica, I had overlooked that a fish of the same genus had been described under the 

 same name in the " Fauna Japonica." These two fishes prove to be distinct, the Japanese 

 species having D. 13-14 and A. 17, whilst the fin formula of the Chinese species isD. 17, 

 A. 22. Houttuyn gives much too little descriptive detail to show what species he had 

 before him ; but as his specimens were also Japanese, his Atherina japonica is better 

 referred to the species described by Schlegel ; thus, the specimens described by me in 

 Fish., vol. vii. p. 390, require a distinct name, Engraulis chinensis. Length of specimens, 

 3^ to 5 inches. Inland Sea, Japan. Kob^.

The length of the head is two-thirds of that of the trunk, the tail being longer than 

 the body ; upper jaw much projecting beyond the lower, rather pointed ; mouth extend-

 of the head, and nearly two-thirds of that of the snout ; posterior nostril a wide, round, 

 open aperture ; length of the pectoral fin one-third of that of the head ; the dorsal com- 

 mences above the root of the pectoral ; vertical fins with a light margin ; terminal portion 

 of the tail black, extremity of the fin white.
