Here described from two specimens, 54 and 62 millimeters 

 long, collected at Amoy, China, by Prof. S. F. Light. Hitherto 

 Giinther's type in the British Museum, from "China," has been 

 the only specimen known.

The compressed body varies from slender to rather deep, 

 usually the latter, with broad flat caudal peduncle; the body 

 covered with ctenoid scales with from 50 to 70 in a longitudinal 

 series, those on nape smaller than those on sides; rarely the 

 anterior scales may be cycloid or absent; the compressed blunt 

 head has a convex profile and is naked to posterior margin of 

 eyes or a trifle farther, except that the upper margin of opercle 

 may be more or less scaled; large pores on head as follows: 

 One near inner side of first nostril, two in a longitudinal row 

 on interorbital space, one behind upper part of eye, a row of 

 five along supraopercular groove, the first immediately behind 

 eye, a row of three on posterior margin of preopercle; the 

 mouth more or less oblique, with the teeth in each jaw in two 

 or more rows, those of outer row larger and fixed, with a stout, 

 backward-curving posterior canine on each side of lower jaw; 

 tongue rounded at tip ; isthmus broad ; the dorsals without sharp 

 spines, the tips of first dorsal more or less elongated; dorsal 

 VI, 1-11 to 16; anal I, 10 to 16; the second dorsal less than 

 twice as long as first; the caudal rounded-truncate; no silky 

 rays on upper part of pectoral. 



This genus is composed of small, mostly deep-bodied gobies, 

 more or less banded or striped, often brilliantly colored and very 

 beautiful in life. It is confined to the East Indies and the south 

 Pacific Ocean.
