FISHES OF SINALOA. 483 



Family SCARID^. 



182. Scarus perrico Jordan & Gilbert. Perrico. 



This large parrot-fish is rather common about the rocky 

 islands near Mazatlan. A single specimen was obtained 

 by us. The original type was found by Dr. Gilbert at 

 the same locality. The fins of another specimen were 

 found on the beach at La Paz by Mr. James A. Richard- 

 son. 



Body olive brown. The markings, fins, teeth and spots 

 on head all bright blue green. 



Family EPHIPPIDyE. 



183. Cheetodipterus zonatus (Girard). 

 Occasionally seen at Mazatlan, several specimens be- 

 ing taken by us in the Astillero. It was found by Dr. 

 Gilbert at Mazatlan and Panama. The original type of 

 the species came from San Diego, where no author sub- 

 sequent to Girard has seen it. It is probably generally 

 diffused along the coast, although less abundant than the 

 corresponding species ( Chcstodipteriis fabe?' L.) is in the 

 Atlantic. 



Chcetodipterus zonatus agrees with Chcetodirpterits fabcr 

 in nearly all respects. The chief differences are that 

 behind the great band from soft dorsal to anal in Ch. 

 zonatus there are two other bands; one under middle of 

 soft dorsal, the other at base of caudal, both distinct com- 

 plete rings; no other bands. The third dorsal spine is 

 not very high, being only about half length of head, and 

 about twice height of the fourth. Dorsal VIII-i, i8; 

 anal II, i6; scales 70. Long rays of soft dorsal and 

 anal ^ longer than head.
