GOBIUS BASSEJSTSIS. 



The anterior dorsal with six spines ; scales large ; no crest on 

 the head ; caudal fin very elongate, pointed. Body very elon- 

 gate ; its height contained seven and one-third times in the total 

 length ; head four and two-third times in the same ; eye four and 

 one-third times in length of head. Jaws about equal, the lower 

 a little longer than the upper. Teeth on several rows at the 

 lower jaw ; no canines. No scales on the head nor on the nape 

 of the neck ; about thirty-eight scales on the lateral line ; they 

 are ciliated on their edge. Dorsals rather high, the second of 

 eleven rays ; caudal as long as the head, pointed, and formed of 

 sixteen principal rays and of several others on each side ; anal of 

 eleven rays, which are, as those of the second dorsal, rather pro- 

 longated ; pectorals about as long as the head, pointed, of fifteen 

 rays, none of which are silk like. 



The general colour is of a light grey, rather green on the back, 

 and whitish on the belly. There are two longitudinal bands, 

 which extend on the operculum, from behind the eye ; the first 

 strikes the upper edge of the root of the pectoral, and expands 

 in a blotch ; the other is placed lower ; it is broader, and extends 

 rather obliquely towards the lower side of the pectoral base. The 

 two dorsals have a longitudinal narrow band, which runs at 

 about one-third of their height from the back ; the extreme edge 

 of the second dorsal is yellow. The caudal has three or four 

 transverse series of black spots, which only extend on its upper 

 half ; the two central rays are of an orange colour, ending in black ; 

 the anal and ventrals are white, without spots ; the pectorals are 

 also immaculate, but with a yellow tinge ; the eye is silvery. On 

 the lower side of the body, there is a longitudinal line of black 

 blotches, which unite under the pectorals ; some feeble, black 

 transverse spots on the upper part of the body. 



Only seen once, in February.
