. In some of this material, particularly in smaller specimens, the adipose fin extends anteriorly into a faint ridge that approaches very close to, but never touches, the base of the last dorsal-fin ray. This is most likely the reason behind Prashad and Mukerji's (1929) assertion that the adipose fin contacts the base of the last dorsal-fin ray in
