caudal peduncle. Snout blunt, shorter than large eye ; upper jaw slightly 

 projecting, teeth small and sharp, in 1 or 2 irregular series in lower jaw, 

 in several series in upper jaw, the outer row slightly enlarged; maxillary 

 extending to posterior edge of pupil; chin with 4 large pores; edge of 

 preopercle covered with skin, which is serrated on the edge. Gill rakers 

 slender, 9 -f- 13 ; scales ctenoid 011 the body, cycloid on the head. Spinous 

 dorsal a little higher than soft dorsal; first dorsal spine very short, second 

 about 5 times longer, third twice as long as second, third, fourth, fifth, 

 and sixth subequal, the others rapidly shorter; first anal spine very small, 

 the second many times longer and stouter, but shorter than soft rays; 

 ventrals inserted behind pectorals and reaching beyond them ; caudal 

 truncate. Ground color silvery, but so closely set with small dark brown 

 points as to almost obscure the silver; sides with about 4 faint dark cross 

 bands and with conspicuous black stripes following the rows of scales, 

 about 11 horizontal stripes below lateral line, those above slanting 

 obliquely upward anteriorly, but becoming horizontal posteriorly; tips 

 of ventrals and anal black, other fins dusky. Here described from a fine 

 specimen from the Astillero at Mazatlan, 8 inches in length. Pacific Coast 

 of tropical America; recorded only from Ma/atlan and Panama; appar- 

 ently rare; our specimens from Mazatlan and Panama much darker than 

 Steindachner's type, which was deeper, the depth 2 in length, (/uaxpos, 

 large; G^, eye.)

 its length 2J- in head; premaxillary anteriorly on level with the lower 

 border of the orbit; lower jaw included; maxillary broad, not entirely 

 concealed by the preorbital when the mouth is shut. Teeth of the lower 

 jaw blunt, conical, in 2 series, those of the inner series much larger than 

 those of the outer; upper jaw with a narrow band of villiform teeth and 

 an outer series of larger teeth, which are remote from each other and 

 decrease in size toward the angle of the mouth. Chin with 5 small pores; 

 snout with 6 pores, arranged in a _- - shaped figure. Preopercle with
