First 2 dorsal spines detached, from tlie others and inserted on or close 

 behind the occiput; scales large, about 26 in the lateral line; lateral line 

 on the second row of large scales below the dorsal sheath. This genus 

 contains some 5 or 6 species, chiefly of the western Pacific. They are 

 similar in most respects to the typical species of XyrichiJiys, differing 

 chiefly in having the 2 anterior spines of the dorsal fin produced, separated 

 from the others, and placed as a separate fin on the nape. {Iviov, nape; 

 idriov, sail, in allusion to the first dorsal fin on the nape.)

Head 3i; depth 2^. D. II-YII, 12; A. Ill, 12; eye 6 to 7 in head, snout 

 2^; first filamentous dorsal spine nearly as long as head; pectoral equals 

 ventral, nearly 2; scales 2-28-11. Body deep, compressed, the profile very 

 steep; the first 2 dorsal spines long and filamentous, not connected with 

 the other spines, the longest spine about 1*^ in head and 4i in body ; height 

 of head equal to its length; anterior profile steep and broadly curved, 

 canines |; a ring of deeply embedded scales around posterior margin of 

 orbit, head otherwise naked; scales on nape deeply embedded; 3 broad 

 bars of dark olive on the back and sides, these bars nearly as wide as the 

 Interspaces ; most of tbe scales of the back and sides with a vertical light- 

 bluish stripe; in the middle of the first dark baud are 1 or 2 scales 

 of a different color, tho posterior half of each jet-black, the base light 

 blue; dorsal with narrow dark stripes running obliquely downward and 

 backward; anal pale; a conspicuous light horizontal stripe near the tips 

 of rays; a narrower similar stripe near the middle of the fin; bluish 

 clouds on opercle; vertical pale-blue stripes below eye, a faint dusky 

 streak below eye ; female paler, plain yellowish or brownish; dorsal with 

 several obli<iue bars between its rays. Rocky Islands on the Pacific coast 

 of Mexico. The original types of this species (females), and afterwards 

 some other specimens, have been sent to the United States National 

 Museum from Cape San Lucas. Specimens have also been taken on the 

 west coast of Mexico by Dr. Gilbert. Length 8 inches. This very hand- 

 some species much resembles tho type of the genus, Iniistius paro, of the 

 Hawaiian Islands, (miindus, neat; corpus, body.)

Body oblong, moderately compressed, covered with large cycloid scales 

 as in the Luhridw. Mouth moderate, terminal. Teeth in the jaws more 

 or less coalescent, at least at base; lower pharyngeals much enlarged, 



*In Cuba, tbe name Yieja (Old "Wife) is applied to all tbe dull colored parrot flsbes: 

 that of Loroto tbe green and blue forms; Ovacamaia to those with green teeth, these
