tlian its depth below top of eye; preorbital f as broad as eye, without any 

 indication of a spine; preopercular spine strong, f length of eye, 3f in 

 head, 3 or 4 verj- short stout spines on upper limb, the longest about 5 in 

 spine at angle, 1 on lower limb ; 1 spine on interopercle ; premaxillary 

 not very broad on top, very protractile, not projecting beyond anterior 

 profile; interorbital greater than preorbital, equal to distance between 

 eye and upper end of gill opening; furrow in front of eye indistinct; 

 dorsal and anal falcate, the filamentous tips reaching much beyond caudal ; 

 pectoral obliqiiely rounded, equal to head, the lower rays very short; 

 ventral spine If in head, the filamentous rays reaching origin of anal, 

 about i longer than head; caudal rounded, longer than head, but shorter 

 than ventral, lateral line ceasing before reaching eud of dorsal, the 

 scales below regularly arranged, those above nearly so. Color in life, 

 yellowish brown on sides, each scale with a darker or orange spot; back 

 shaded with violet, which grows brighter and merges into intense sk>' blue 

 along the edges of spinous dorsal and on the region before the dorsal; 

 scales of dorsal region with brown spots like those on sides; head paler; 

 the upper lip yellowish ; lower jaw reddish ; spines of preopercle and edge 

 of opercle very bright sky blue; iris yellow, marked above and below by 

 blue ; a blue bar extending from in front of first dorsal spine halfway to 

 eye ; breast sky blue ; pectoral sky blue at base, then broadly golden, its 

 edge pale; ventrals golden; posterior edge and produced lobes of dorsal 

 and anal golden yellow, caudal broadly edged with yellow; no distinct 

 ocellus at nape, and no dark-blue edgings to soft dorsal and anal. This 

 species is closely related to Ant/cUchtluis ciliaris, but differs decidedly in the 

 color markings, especially those of the nape and dorsal, in the great depth 

 of the head, and in the nonprojecting mouth; also somewhat in general 

 cimtour of body. Florida Keys and probably neighboring waters ; com- 

 mon; reaching a large size. This description is based on the type, a sin- 

 gle specimen 4^ inches long, from Key West, Florida, collected by Dr. 

 Jordan. {Isahelita, the Spanish name.)

Head 3?; depth 1| (2 in total); eye 4),. I). XIV, 20; A. Ill, 20. Body 

 very deep, forming almost a regular ellipse, slightly concave above and 

 in front of eye. Preorbital without spine, sht)rter than width of inter- 

 orbital, which is narrower than distance between eye and upper end of 

 gill opening; spine at angle of preopercle straight, longer than orbit^ 

 about equal to preorbital; 8 or 9 spines on upper limb of preopercle, these 

 nearly i as long as the one at angle, very nuich longer than in Aiuiel- 

 ichthys ciliaris; 2 weak spines on lower limb, aud 2 on" interopercle. 

 Soft dorsal and anal falcate, the longest rays fihimentous; pectoral very 

 obliquely rounded, the lower rays scarcely i as long as the upper, which 

 are li in head; ventral slightly filamentous, eiiual to head. Lateral line
