Head and body strongly compressed. Mouth terminal, protractile, 
very oblique. Premaxillaries with 6 canines on each side of symphysis, 
and with lateral teeth smaller, uniserial. Gill opening vertical, in 
front of base of pectoral fin, not produced forward below. Head naked. 
Body covered with small scales. Two dorsals, first of 5 spines, second 
of 16 or 17 rays. Anal with feeble spine and 15 rays. Ventrals close 
together, separate, each with spine and 4 rays. 
According to Regan, intermediate between Allogobius Waite 1904, 
and the other Gobiid genera\with only 4 soft rays in the ventral, in 
the basal length of second dorsal and anal fins. Allogobius has large 
scales, soft dorsal rays 10, anal rays 8 , head only slightly compressed, 
and mouth very oblique. loglossus Bean 1882 is nearer Farioglossus , but 
seems to differ in the wider gill openings, and dorsal rays 22 to 24. 
Vireosa Jordan and Snyder 1901 has a mental barbel, and Oxymetopon Bleeker 
and Orthostomus Kner are distinguished by having at least 3° ra y s in 
second dorsal and anal.
