<paragraph id="F9A0975847A237B7C0B310845A9B9E67" pageNumber="11">This is a robust, compact fish, body terete forward, tapering to being slab-sided in the caudal peduncle region. Dorsal profile is slightly arched and the ventral profile is almost flat. Deepest part of the body is just anterior to the dorsal-fin origin, at about 25% SL (see Table 5 for means and ranges of all measurements). Caudal peduncle depth is about 15% SL, so the body profile varies little. Caudal peduncle is longer than deep. Dorsal-fin origin is about 60% SL; anal-fin origin about 70% SL; however, both fins extend back to about 80% SL, so that the insertion of the anal fin is below the midpoint of the dorsal fin. Caudal fin is rounded. Pectoral fins are thoracic and ventral; pelvic fins are abdominal and ventral. The body is entirely scaled, with modified scales encroaching onto the caudal rays.</paragraph>

The head is about 30% SL. The postorbital length is slightly greater than 50% head length (HL). The snout, at 20% HL, is blunt, relatively short, and usually its length is less than the orbit diameter. General shape of the head is conical, with greatest depth posterior, tapering to snout. Eyes are dorsal. Mouth is terminal, horizontal and non-protractile. There are teeth on the premaxillary, dentary, vomer and palatine. Paired nostrils are on the snout anterior to the eyes, each has simple incurrent and excurrent openings. Head is scaled; only the chin, anterior part of the snout, and gular and branchiostegal areas are free of scales. Cephalic lateral line system comprises supraorbital, infraorbital, temporal and preopercular canals, each with relatively few pores. All canals are separate. The supraorbital canal is branched and has four pores; the anterior pore is near the excurrent nostril opening, the third pore is on a branch, the posterior pore is posterior to the orbit and

near the anterior pore of the temporal canal. The infraorbital is Y-shaped, has three pores, is anterior of the orbit and does not extend below the orbit. The temporal canal has two pores, the anterior pore near the terminus of the supraorbital canal, the posterior pore just above the terminus of the preopercular canal. The preopercular canal is branched and has four pores. The anterior pore is below the mid-point of the eye, the second and third pores are on branches and the fourth pore is just below the temporal canal. Pitlines are numerous (see Nelson (1972) for details). The operculum is rounded, relatively large and has a flap of skin along its entire margin; its angle is slightly obtuse. The preoperculum is right-angled and is free only at its angle. The four or five branchiostegal rays are short and thick. Gill membranes are free from the isthmus.

Ventral and dorsal procurrent rays present. The 12-14 dorsal fin rays are progressive, although the posteriormost rays may be shorter that those immediately anterior. Anal fin typically has 9 rays with the longest rays in the middle. Pectoral fin insertion is just posterior to angle of operculum and its base is small and oblique. Pectoral fin rounded, slightly asymmetrical, with 13-14 rays. Usually both pectoral fins have the same number of rays and the middle rays are longest. Pelvic fin insertion is just anterior to dorsal fin origin. There are six pelvic rays with middle rays longest.</paragraph>

There are several dark, usually more than eight, thin stripes that run the length of the body, each is separated by a light stripe of equal or greater width. There is a prominent vertical dark bar at the distal edge of the caudal peduncle. Head is dark; operculum is heavily pigmented; cheek is lighter than operculum. The cheek is framed by either an oblique, pigment-free line just below the eye or by an inverted “V” without pigment that includes the suborbital lateral-line canal and a second line that parallels the preopercular canal. The opercular flap is lightly pigmented. The proximal edge of the caudal fin is also heavily pigmented. Fins often have a weak red or maroon tint in life.</paragraph>

, there are several errors in the text and figure (Fig. 134, DeKay 1842). The original description notes that a lateral line is present, that teeth are absent, and nostrils are inconspicuous. However, it is DeKay’s descriptions of the fins that are most puzzling. The caudal fin is described as lanceolate and is figured as long

tapering. The pelvic fins are described as filiform (although not illustrated as such). The dorsal fin is described and illustrated as emarginate. He described the vertical fins as annulate, which is difficult to understand unless he was referring to the structure of the rays. The illustration is labeled as “Nat Size”, but measures 1.5 inches in contradiction to DeKay’s statement of maximum size.

. So, he named them after the Pygmaioi (Latin Pygmaea), who are, in Greek mythology, a diminutive, dark-skinned tribe that lived on the shores of the River Okeanos and who were tenacious in fighting a never-ending battle with cranes. DeKay probably knew his mythology well and thought the name appropriate for several reasons:
