1. GOBIUS LYRICUS, Grd. 

 Plate XII, Figs. 4 and 5. 



Spec. Char. — Body compressed, fusiform in profile. Head anteriorly rounded, contained five times and a half in the 

 total length. Jaws sub-equal ; gape of the mouth nearly horizontal ; posterior extremity of maxillary reaching a vertical line 

 drawn through the pupil. Branchial isthmus wide. Dorsal fins not contiguous. Middle rays of first dorsal filiform and 

 membranous at their tips, higher than the second dorsal, the posterior rays of which, as also those of the anal, reach the base 

 of the caudal. The caudal fin itself is lanceolated, and the anal nearly as long as the second dorsal. The tips of the ventrals

 so deep.
