Body ovate, laterally compressed (Figure 1); greatest body depth (34.9–48.7% SL) anterior to body midpoint (usually at vertical between anal-fin rays 10–15), with noticeable taper posterior to this point and gradual taper anterior to this point. Caudal peduncle short. Head small (20.8–28.4% SL), averaging 4.2 times in SL; with slight notch on dorsal profile just anterior to anterior margin of upper eye. Snout short, much shorter than eye diameter (average 2.1 times in ED), slightly to bluntly pointed. Ocular side of snout with scales reaching nearly to anterior margin and with small, triangular-shaped, wedge of scales on snout region posterior to nostrils, the apex of this triangle extending posteriorly into interorbital space.

B). Ocular-side nostrils located closer to horizontal through dorsal margin of lower eye than to horizontal through ventral margin of upper eye. In both sexes, ocular-side anterior nostril a short, round tube with opening located dorsal to anterior third to midpoint of upper jaw and surrounded by short, fleshy tubular nostril with an extended wide flap posteriorly; length of nostril about twice that of diameter of nasal opening. Posterior ocular-side nostril in both sexes a rounded to sphericalshaped opening, with or without slightly raised circular rim located slightly posterior to vertical through midpoint of upper jaw. Blind-side nostrils in both sexes smaller, more translucent, and less conspicuous than ocular-side nostrils; located on snout antero-ventral to dorsal-fin origin.

Anteriormost 5–6 dorsal-fin rays shorter than remainder of dorsal-fin rays, but increasing successively in length posteriorly. Beginning with second dorsal-fin ray, anteriormost 2–10 rays with membrane only on basal half; more posterior rays with membrane nearly to distal tips and with short, distal tips free from membrane. Dorsal and anal fins free from caudal fin. Anal and dorsal fins with sheath of scales covering basal portions of fins, but without scales on fin rays. Pectoral fins developed on both sides of body; asymmetrical; ocular-side pectoral fin nearly twice as long as blindside counterpart. Both pectoral fins with several dorsalmost interior rays longer than marginal rays and other interior rays; no rays elongate. Ocular-side pectoral fin with several, small scales on its base. Pelvic fins developed on both sides of body; asymmetrical, with ocular-side fin nearly twice as long as blind-side counterpart. Pelvic fins with membranous connection to body posteriorly, but free from each other and free from anal fin. Distal tips of pelvic-fin rays free from membranes. Ocular-side pelvic fin with middle rays longer than other rays; origin of ocular-side pelvic fin at tip of isthmus and with its anterior rays situated nearly on ventral midline with more posterior rays inserted gradually more dorsally on right side above midline and positioned noticeably more dorsal than anterior rays. Blind-side pelvic fin short-based, usually with 5 rays; its origin about opposite base of seventh ray of ocular-side pelvic fin. Blind-side pelvic fin with anterior rays closer to midline and with posteriormost rays positioned more dorsally away from midline, but not as noticeably as those of ocular-side pelvic fin. Caudal fin relatively large, approximately 4.5 times in SL, rectangular with central rays slightly longer than marginal rays. Central caudal-fin rays branched, marginal rays unbranched. Both sides of caudal-fin rays with ctenoid scales nearly covering their entire lengths.

The most conspicuously different pigmentation features of these specimens are three longitudinal series of darker, elliptical to circular blotches. All blotches contain numerous, conspicuous, small melanophores. One series, located medially along lateral line, usually contains 4–6 large (ca. equal to 40% of ED), nearly spherical blotches. A second longitudinal series appearing on the body dorsal to the lateral line and near bases of dorsal- and anal-fin rays consists of 3–5 blotches, while the third longitudinal series (3–4 blotches) lies ventral to the lateral line near bases of the anal-fin rays. Blind sides of juveniles are uniformly whitish, which is similar to that of adult fishes, but lack pepperdot melanophores on their blind-side scales. The peritoneum is dark black and more conspicuous through the juvenile’s thinner abdominal walls. All dorsal- and anal-fin rays are pigmented as those in adults, but differ in their pattern of 2–4 darkly-streaked fin rays alternating with 2–3 more lightly pigmented fin rays.

. Again, as for some of the other characters examined, counts of lateral-line scales between these species are not completely different when a larger series of specimens are examined. Nearly one-third (23/76= 30%) of the total number of specimens (both species) have overlapping counts (95–100 scales) for lateral-line scales (Table 1), which restricts the value of this feature in distinguishing the two species. In the few examples where it was possible to make accurate counts,

. However, this count has limited application for identifying specimens because all but a few individuals of both species are missing all or most of their scales, and often these specimens also have many scale pockets torn as well, rendering it difficult to quantify this character accurately. Even when most scale pockets were intact, attempts to estimate scale counts in a subsample of these specimens based only on this count were also unsatisfactory, and consequently it was not possible to clearly distinguish the species.

, respectively, have commented on the significance of differences in their ocular-side color patterns. In geographically separated populations such as these, it is often difficult to determine whether differences in color patterns are species-specific characteristics, or if they indicate intraspecific variation among populations of the same species. This difficulty is compounded when study subjects are flatfishes and when only small numbers of specimens are available for study. Differences in morphological and meristic characters (discussed above), which are based on a large series of samples, support the hypothesis that

. Fin-ray counts for the third specimen are inconclusive. Further hindering positive identification of these three specimens is that their scales are either not developed or are missing, preventing use of lateral-line scale counts and blind-side squamation patterns to help identify them. Gillrakers were not fully developed, so accurate counts for this feature were also not available. No scales were observed between the eye and jaw in these specimens, but it is unknown how early in development this character appears in young
