Genus 112. CARANGUS Griffith. The Cavallas. 
“ Papiopio,” small size; “ Pa'upa'u,” medium size; “ Vlua,” large size. 
Body ovate or oblong, compressed, the back sometimes considerably elevated, sometimes little 
arched; head moderate or rather large, more or less compressed; mouth moderate or large, oblique; 
maxillary broad, with a well-developed supplemental bone extending to below eye; premaxillaries pro- 
tractile; teeth developed in 1 or few series, unequal, or at least not in villiform bands; villiform teeth 
usually present on vomer, palatines, and tongue, wanting or deciduous in some species; gillrakers long; 
eye large, with an adipose eyelid; dorsal spines rather low, connected; second dorsal long, usually 
elevated in front, both tins depressible in a groove; anal fin similar to second dorsal and nearly 
as long, preceded by 2 rather strong spines, its base longer than the abdomen; caudal fin strongly 
forked, the peduncle very slender; ventral fins moderate; pectorals falcate; no finlets; preopercle entire 
in the adult, serrate in the young, usually witli a membranaceous border. Species very numerous in 
all warm seas, most of them valued for food. 
About 9 species of this genus are now known from the Hawaiian Islands.
