Genus 57. AMBLYCHAETURICHTHYS Bleeker 



Amblychaeturichthys BLEEKER, Esq. Syst. Gobioides, Arch. Neerl. Sci, 

 Nat. 9 (1874) 324. 



This genus is separated from Chaeturichthys by having a 

 smaller number of scales, fewer rays in the soft dorsal and 

 anal, and by the absence of fleshy papillae on the inner edge of 

 the shoulder girdle. The body laterally compressed, with 32 to 

 40 scales in a lateral series; the head is scaled and has three 

 pairs of small barbels under lower jaw; the teeth of upper jaw in 

 two rows, the outer ones enlarged, fixed, straight, awl-shaped; 

 those of lower jaw in three rows in front, two at sides, those of 

 outer row longest, straight, depressible, directed obliquely in- 

 ward ; the tongue truncate. Dorsal VIII, 15 to 17 ; anal I, 12 or 

 13 ; caudal pointed or rounded, a little more or less than head ; 

 no silky rays above on pectoral. 



This group comprises a few small, plainly colored gobies from 

 the coasts of China and Japan.
