PART II. SYSTEMATIC ACCOUNT 



ends of the keels do not meet (Fig. В 1695), nor do the ventral ends which are 

 raised up above the surface of the body as tall crests (Fig. B169C). This is a 

 peculiarity shared with L.johanssoni, and the complex structure of the keels 

 recalls those of L. ivanovi. The ridges of the bridle are rather narrow and only 

 discernable on the lateral and dorsal sides of the body (Fig. В 1695, С). There 

 is no median furrow either in front of or behind the bridle.
