referred to the genus Gobius. The chief distinctive characters 

 of the present genus repose on the pectinated scales, the approxi- 

 mated eyes, and the slender and scattered pharyngeal teeth. 

 Several species of Chinese and Japanese Gobies, of which 

 Gobius flavimanus of Temminck and Schlegel may be con- 

 sidered as the type, appear to be referable to this or a closely 

 allied genus. 



Ctenogobius fascial us, Gill. 



Body oblong, with dorsal and abdominal outlines straight, 

 converging as they approach the caudal fin ; anteriorly, it is 

 thick and little compressed, the size at the pectorals being three 

 quarters of the greatest height, which is little more than one- 

 seventh of the entire length ; the thickness gradually diminishes 

 to the tail, which is much compressed. The head is less than 

 a fifth of the total length, inclusive of the caudal ; the eyes are 

 more than a quarter of the length of the head, and are distant 

 the length of one of their diameters from the snout ; the space 

 between them is only two-sevenths of an orbit's diameter. The 

 first dorsal commences at a distance from the snout of less than 

 a quarter of the entire length ; the space between it and the 

 second dorsal is equal to the diameter of the orbit. The anal 

 commences under the second ray of the second dorsal ; the pec- 

 torals are pointed, and extend as far back as the margin of the 

 united ventrals, or to the posterior border of the anus.

The prevailing color of the body is sienna tinged with yel- 

 low ; on the side, there are four dark linear black spots in a 

 line, the distances between which are as great as their length. 

 A dark spot and numerous black dots color the base of the 

 caudal fin. The dorsal fin is of a raw sienna color, and is 

 crossed by three or four sublinear black spots. The caudal is of 

 the same color, crossed by five zigzag linear bands of black. 

 The anal pectorals and ventrals are of a uniform sienna. Head
