*Based on Robins’ [8∶592] description of gill rakers, he did not count the rudimentary pads on the lower limb of the first arch, only those on the upper limb.
**Robins [8∶592] erroneously gave this value as 7.0. The least depth of caudal peduncle was re-measured by R. Robins (pers. comm., 2 Oct 2013) as 15.2 mm, or 14% SL.
