than the length of the head. The middle limb of the corselet is prolonged 
backward nearly the entire length of the lateral line. 
The dark coloured portion of the lateral muscle is nearly equally large in 
the hypaxial and epaxial portions. 
Depression along the suture between the prootic and the alisphenoid is 
sharply defined and narrow, and the shelf at the anterior border of the de¬ 
pression is obsolete. Only two intermuscular bones have the middle portion 
non-ossified. The lateral process of the second vertebra is short and thick. 
Neural process of some anterior vertebrae is not so broad as in the preceding 
species. The haemal arch of the first caudal vertebra makes a right angle with 
the epihaemal spine. From the lower end of the epihaemal spine a pair of 
short free processes is produced downward and forward in some caudal vertebrae. 
Free parapophyses from the lower end of the epihaemal process are short, and 
are but a little separated from each other. 
This species seems to be more abundant than the preceding species. In 
distribution nearly the same as the latter. Known from South-Manchuria as 
well. Caught in pound-nets, set-nets, drift nets, rods and lines, etc. 
Grows to a weight of ca. 640 g, the smallest species in the Plecostei. 
Very poor food-fish, consumed fresh or salted. 
Auxis tapeinosoma of Bleeker seems at first sight to be identical with this 
species, but not exactly, as the dorsal finlets of the former are characterised 
as 9 in number.
