Analysis of variance of total dorsal scales within these two groups, paired with Duncan's Multiple Range Test, suggests that these three taxa represent three full species.
dulcis whose total dorsal scale count varied from 214-245, and only four of which had an anterior supralabial combination of 1/2 (an undivided anterior supralabial on one side, but divided on the other); L.
The authors felt that the high variability of dorsal scale count indicated that further study was warranted.
3) in total number of dorsal scales, the lowest number ever recorded for L.
dulcis dissectus examined, the total number of dorsal scales varied from 220-255 (mean 236.
Anterior nostril on level with median axis of orbit; posterior nostril same size and situated slightly dorsal to anterior nostril; anterior nostril with large, leaf-shaped flap that tapers distally, length of flap when depressed 0.
Dorsal and anal fins each flanked basally by 10-12 half scales, remainder of dorsal and anal fins without scales; large, diamond-shaped scales covering pelvic-fin base, remainder of pelvic fin and pectoral fin without scales; 6 rows of body scales extending onto base of caudal fin; upper and lower caudal lobes each with a single, enlarged, horizontally elongate scale.
3A) Head and dorsal half of trunk gray to greenish brown, ventral half of trunk pale; 6-8 dark brown markings along length of trunk laterally, at least some of them resembling wide crosses that are widest along lateral midline; markings on left and right portions of trunk connected to one another across dorsal midline to form saddles; trunk also with several thin orange-yellow stripes dorsally, stripes thicker or broken into orange blotches ventrally; groove above maxilla with stripe of black pigment from below anterior edge of orbit to posterior end of jaw; posterior edge of branchiostegal membrane pale yellow; scapular region with large black blotch of pigment partially hidden by operculum, length 3.
