of new species were made by Fanny L. Phillips; the photographs 

 were taken by the author. 



Standard length was taken from the front of the upper Up with 

 mouth closed to the base of the caudal fin (that is, end of hypural 

 plate). Head length was measured from the front of the upper lip to 

 the most posterior part of the opercular membrane, snout length from 

 the front of the upper lip to the edge of the eye, and length of caudal 

 peduncle from a vertical at rear base of dorsal fin to base of caudal fin. 

 All fin rays that have a separate basal element, regardless of spacing, 

 were counted. Scale rows above the lateral Une were counted in the 

 middle of the body. Only the rows of large scales were counted; 

 once a rov/ of scales showed a marked diminution in size to the row 

 beneath it, it was not counted. If the scale rows are counted from 

 the lateral line to the origin of the dorsal fin, there is often one scale 

 more than may be counted in the middle of the body. Gill-raker 

 counts include rudiments. Capped roman numerals designate spines 

 and lowercase roman numerals unbranched soft rays (pectoral counts 

 only). The number of serrations on the free margin of the preopercle 

 increase with age (fig. 1); therefore, this count is often without value 

 unless lengths of specimens are given. The number of specimens on 

 which meristic data are based is enclosed in parentheses after the 

 counts in species discussions, along with locahty or localities of these 

 specimens. All counts are included in species diagnoses, although 

 not all are diagnostic. Chp.racters given in the diagnoses and key to 

 genera are usually not repeated in species accounts. 



Key to the Genera of the Cirrhitidae ^ 



la. Scales ctenoid; 3 spines on opercle; 2 rows of scales above lateral line (sub- 

 family Isobuninae) Isobinia (p. 393) 



lb. Scales cycloid; 2 indistinct flattened spines on edge of opercle; 3 to 5 rows 

 of scales above lateral line (subfamily Cirrhitinae). 

 2a. Snout not elongate, its length about 3 to 5 in head length; body not 

 slender, the depth 2 to 3.4 in standard length; canine teeth in jaws 

 markedly longer than inner villiform teeth, those at front of upper 

 jaw and side of lower jaw enlarged. 

 3a. Caudal fin rounded, truncate, or slightly emarginate; dorsal soft rays 

 11 to 15. 

 4a. No large scales on cheek (small scales in more than 12 irregular rows). 

 5a. Body not deep and not compressed, the depth 2.6 to 3.4 in standard 

 length and the width 1.5 to 1.9 in depth; dorsal soft rays 11 

 (rarely 12); palatine teeth present; upper margin of preopercle 

 finely serrate or smooth; lower 7 pectoral rays unbranched. 



Cirrhitus (p. 395) 



' The Japanese genus SerranocirThitus Watanabo (1949), no specimen of which has been examined, Is not 

 considered in the present paper. Although this genus may ultimately be placed in the Cirrhitidae as 

 intended by Watanabe, it differs notably from other clrrhitids in having all the pectoral rays unbranched 

 and not thickened, no teeth on the vomer, and the configuration of a pomacentrld. Like Isobuna, it has 

 ctenoid scales.
