IACI 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 EPHIPPIDZ. 
183. Chetodipterus 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 ot 
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 (Chetod7pterus faber L.) is in the 
Atlantic. 
Chetodipterus zonatus agrees with Chetodipterus faber 
in nearly all respects. The chief differences are that 
behind the great band from soft dorsal to analin C2. 
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-1, 18; 
anal II, 16; scales 7o. Long rays of soft dorsal and 
anal 4 longer than head.
