being taken in the perpendicular through the first ray of 
the anal fin); the anal fin 1s usually less than 85 « of the 
distance from the first dorsal fin to the tip of the snout and 
usually less than half its distance from the tip of the snout; 
dark spots arranged in cross-bands are usually wanting in the 
ventral fins. 
Cottus gobio LIiNN2AUS forma poecilopus HECKEL: The inner- 
most ray in the ventral fin is less than half the length of the 
fin (about !/3 of it); the distance between the lateral line and 
the second dorsal fin is less than 60 2 of the distance between 
the lateral line and the first ray of the anal fin (both the 
measurements being taken in the perpendicular through the 
first ray of the anal fin); the length of the base of the anal 
fin is usually more than 85 « of the distance from the first 
dorsal fin to the tip of the snout and generally more than half 
its distance from the tip of the snout; dark spots arranged in 
regular cross-bands exist as a rule in the ventral fins.
