FAMILY LABRIDAE—SCHTJLTZ 139 The genus Wetmorella is characterized by dorsal rays IX or X,9 or 10; anal 111,8; pectoral ii,9 or 10; branched caudal rays 6+5; lateral line interrupted with 13 to 15+6 or 7 pores to base of caudal fin. Jaws equal or nearly so; premaxillary protractile; teeth short, conical, in a single row in both jaws, those near front of both jaws becoming gradually enlarged, the two pairs nearest tip of jaws largest; gill mem- branes broadly joined across isthmus, forming a free fold; head with a distinctive scale pattern composed of large characteristically shaped scales, arranged in a pattern similar to that shown in figure 96. The chief variation in scales on the head is that there may be 2 median scales on the snout instead of 1; cheek with 1 or 2 rows of scales, below which on subopercle may occur another row and a single scale below that; 2 or 3 rows of scales behind eye, including the gill cover; a row of large scales occurs above dorsal lateral line, then a second row along spiny dorsal fin, mostly covering the spines except tips, becoming much smaller along soft dorsal rays, almost disappearing on base of last ray; anal fin with a similar sheath of scales; basal half of caudal fin enclosed in large scales; axillary pelvic scale present, short; interorbital space flattish and a little convex; dorsal profile of head nearly straight, forming an angle of 40 to 55 degrees with ventral contour of head; maxillary covered by preorbital when mouth is closed. A blacldsh ocellate spot in pelvics, and at rear of soft dorsal and anal fins; white bar behind eye and one on caudal peduncle. Counts for the species of Wetmorella are recorded in table Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United States National Museum; S
