This genus is allied to Eyphosus, from which it differs in the weaker gill 

 rakers; in having the margin of the prcopercle entire ; in having no teeth 

 on the tongue; in the squamation, the scales on the body being larger; 

 head not so completely scaled ; top of head, snout, preorlntals, space below 

 the eye, chin, and preopercles, naked. It also differs in the relative sizes 

 and forms of the vertical tins; the si)inous dorsal is much longer than the 

 soft dorsal, and the soft anal is higher and shorter than the soft dorsal. 

 One species, from the Pacific Coast of Mexico. (Hermosilla, name of the 

 capital city of Sonora, along the coast of which State the typical species 

 was taken, the name derived from Spanish hermoso, beautiful; Latin, 

 foi'mosus.)

Head 3 ; depth 2 ; eye 3^ in head. D. XI, 11 ; A. Ill, 10 ; scales 11-55-17. 

 Body ovate, compressed, head short, snout 3 in head, blunt; maxillary 

 barely reaching front margin of eye, 3| in head. Each jaw with a single 

 series of close-sot, equal, narrow, rounded incisors, the A'illiform teeth 

 behind them small or obsolete, not evident in the type; teeth on vomer 

 not evident in the type; gill rakers slender, the longest about the diam- 

 eter of the eye, 3-|-12; preopercle entire; preorbital f diameter of eye, 

 nearly covering the maxillary. Top of head as far back as the pos- 

 terior margin of the eyes, snout, preorbitals, a narrow space below eye, 

 chin and preopercles, naked; top of head covered with pores; pre- 

 opercles with a network of grooves: remaining parts of head and body 

 scaled; 5 rows of scales on cheek below eye, about 6 rows on the oper- 

 cle; subopercle with 1 row; fins, with the exception of the spinous dor- 

 sal, covered more or less with fine scales; scales moderate, ctenoid, not 

 crowded anteriorly; lateral line complete, traceable but a short distance 

 on the caudal. Dorsal fin with 11 spines, the seventh, which is the 

 longest, H in head; the alternate ones very strong, the spinous part con- 

 tinuous with the soft portion, the last spine not much lower than the soft 

 dorsal, thus leaving but a slight depression between the two; the spinous 

 ])art depressible into a groove; base of spinous part about ^ longer than 

 the base of the soft portion; soft anal shorter and higher than soft 

 dorsal; anal with 3 spines, .short but strong, the second the longest, 1^ 

 times diameter of eye; caudal forked, upper fork the longer; pectoral 

 IJ^ in head, not quite equaling the ventrals which begin behind them. 

 Depth of caudal peduncle 7 in body; interorbital space 2f in head;
