less than that between second and third, which is close to lateral line. AO in two groups, 

 well separated from one another; anterior 9-1 1, the first elevated and level with the 

 middle SAO, the last sometimes a little elevated ; posterior 7, generally well separated from 

 Pre series, although in one or two specimens the two are continuous. 2 (occasionally 3)

Described from numerous specimens, 43-77 mm. in length.
