Length of head 4£ to 5, height of body 5 to 5J in the total length. Eyes— diameter 1/4 to 1/5 of length 

 of head, 1 diameter from end of snout, and 1/2 a diameter apart. Head rather higher than broad : snout 

 obtuse : cleft of mouth a little oblique, commencing opposite the centre of the eyes, the maxilla reaches to below 

 anterior edge or first- third of the orbit. Teeth — two or three rows in either jaw, with an outer row of about 10' 

 large ones in the premaxillaries : outer row in the lower jaw enlarged, elongated, and sub-horizontal, 

 the outer one or two of which on either side are large, obliquely placed, canines. Fins — dorsal spines weak,, 

 having filiform terminations, the two dorsals of about equal height, and the bases of the two separated by a very 

 short interspace. Pectoral nearly as long as the head. Caudal rounded, its central rays the longest. Scales — 

 ctenoid, 16 rows between the bases of the second dorsal and anal : anterior to the dorsal fin they are 

 very small, and are continued forwards to opposite the middle of the eyes, whilst there are a few on the upper 

 portion of the opercle : those on the free portion of the tail are the largest. Colours — greenish, back with from 

 eight to ten darkish cross bars. Two longitudinal bands, the superior from the snout through the eye, at first 

 black, becoming yellow on the body and ending at the extremity of the soft dorsal : the second from the mouth 

 to the pectoral, forming a dark band across the opercles, becoming a black spot at the base of the pectoral, and 

 continued as a golden band to the centre of the base of the caudal, which last fin has a dark spot at the upper 

 part of its base : anal with a dark margin. 



* By L. tr. is signified in the Gobies the number of rows of scales between the origins of the second dorsal and anal fins.
