shore also. Both juveniles and adults are usually 

 solitary but are sometimes seen in small groups. 

 The rock beauty occurs in an area of the west- 

 ern Atlantic bounded by: Cumberland Island 

 (Georgia), Bermuda, Bahamas, Turks Islands, 

 Hispaniola, Puerto Rico, Virgin Islands, Guade- 

 loupe, Barbados, Trinidad, Rio de Janeiro (Bra- 

 zil) , Salvador' (Brazil), Natal (Brazil), British 

 Guiana, Curasao, Cuba, and Tortugas (Florida).

pigmy angelfish 

 Figures 16-17 



Characterized by 14 spines in the dorsal fin 

 (rarely 15) ; adults with the caudal fin and most 

 of the body a bluish-black. Dorsal soft rays 15- 

 17 (usually 16). Anal fin with 3 spines and 

 16-17 soft rays. Pectoral fin with 1 spine and 

 15-16 soft rays. Lateral-line scale pores 36-42 

 (usually 38) . Gill rakers 21-24 (usually 22-23) . 

 Maximum size: from literature records, 53.5 mm 

 SL; from personal collections, 62.1 mm SL (3.5 

 inches TL) , 14.5 g. 



Other common names for this species are vel- 

 vet angelfish and cherubfish. 



The pigmy angelfish is rare in shallow waters 

 but is abundant in certain areas in deeper waters 

 off southeast Florida and the Bahamas, in areas 

 of coral and rock. In Martinique, the species 

 has been found at a depth of 252 ft. Both the 

 juveniles and adults occur singly or in small 

 groups. 



The pigmy angelfish at present is known to 

 occur in an area of the western Atlantic bounded 

 by: West Palm Beach (Florida), Bermuda, 

 Bahamas, Dominican Republic, Virgin Islands, 

 Martinique, Curasao, Colombia, Yucatan, and 

 Florida Keys.

 spectively. They also helped to review the man- 

 uscript and make suggestions. 



Mr. George C. Miller and Dr. Robert V. Miller 

 of the Tropical Atlantic Biological Laboratory 

 helped orient my thoughts on the relationships 

 among the species, and the former aided in the 

 final preparation of this manuscript which has 

 been abstracted from a portion of my doctoral 

 dissertation at the Rosenstiel School of Marine 

 and Atmospheric Science, Miami, Florida.
