FIGURE 1. Landmarks and distances measured. See Table 1 for definitions of landmarks and
Table 2 for names of interlandmark distances.
Meristics include the following: lateral plates are the number of plates with the lateralline
canal from the first complete plate posterior to the pterotic-supracleithrum up to, but
not including, the elongate plate that covers the insertion of the caudal-fin rays; dorsal-,
pectoral-, pelvic-, anal-, and caudal-fin ray counts include the first one or two unbranched
rays as spines; dorsal and ventral procurrent caudal-fin rays; number of teeth in the left
dentary and premaxilla includes only those teeth that are fully erect; evertible cheek odontodes
include only those hypertrophied odontodes that have erupted from the fleshy odontode
sheath and that are between the posterior end of the mass and the area where plates
become clearly visible and are no longer covered by thick skin anteriorly.
