base with the same dark inner and pale outer edges; median fins also 

 with irregular spots. Valenciennes described the life color as olive- 

 green, the spots and bands lighter with dark olive inner and cobalt 

 blue outer borders. The fins are olivaceous with blue rivulations. 



Kemarks. — The holotype (MNHN A5563) is a dried specimen 

 mounted on wood; the length given by Valenciennes is 445 mm. 



C. rivulatus is probably the largest species of the family. Tee-Van 

 (1940) recorded a specimen 450 mm. in total length (his addendum 

 report of a 505-mm. specimen from the Galapagos Islands, USNM 

 38302, is erroneous; this specimen measures 360 mm. in total length). 

 Another USNM specimen (144465) from Bona Island, Panama is 

 520 mm. in total length and 430 mm. in standard length. 



Gregory (1933; p. 259, fig. 135) has briefly described the osteology 

 of rivulatus. Widely distributed in the tropical eastern Pacific.

Cirrhitxis atlanticus Osorio, 1893, Jorn. Sci. Math. Phys. Nat. [Acad. Sci. Lisboa], 

 ser. 2, vol. 3, p. 138 (type locality, Ilheo das Rolas, west Africa). 



Diagnosis. — Dorsal rays X,ll; anal rays 111,6; pectoral rays 

 i,6,vii; lateral-line scales 46 (47); 4 rows of large scales above lateral 

 line in middle of body; 10 scales below lateral line to origin of anal 

 fin; gill rakers 5 + 1 + 13 (1 specimen). 



Bony supraorbital ridge low and not extending posterior to eye; 

 pectoral fins do not reach tips of pelvics; small scales on interorbital 

 space; depth of body about 3 in standard length; longest dorsal 

 spine about 2.3 in depth; caudal fin slightly emarginate. 



Color in alcohol brown, the upper half of the body darker, especially 

 posteriorly, and containing 4 pale blotches at base of dorsal fin; 

 first white blotch centered at base of eighth dorsal spine, the second, 

 somewhat larger (slightly larger than eye) and roughly square in 

 shape, located from base of second to fifth dorsal soft rays, the third 

 at base of last 3 dorsal soft rays, and the last dorsally on caudal 

 peduncle; no irregular white spots on head, as described by Osorio, 

 are now visible, and the row of white spots below the lateral line 

 mentioned in his description is now very faint. 



Remarks. — The type (No. 510), which was examined at the 

 Museu e Laborat6rio Zool6gico in Lisbon, is in good condition. The 

 following measurements and notations were made from the specimen : 

 standard length 155.5 mm.; total length 192 mm.; depth 51 mm.; 

 head 54 mm.; width 23 mm.; eye 9.5 mm.; bony interorbital 8 mm.; 

 pectoral fin 40 mm., longest dorsal spines (fourth to sixth) 22 mm.; 

 first dorsal soft ray 23 mm.; upper margin of preopercle finely serrate,
