scales on cheek. Fins medium, dorsal slightly behind anal, midway 

 between tip of caudal and posterior rim of orbit, the distance from tip of 

 snout to origin of dorsal being twice the distance from that point to base 

 of caudal fin ; dorsal and anal low, their longest rays half length of head ; 

 base of anal '1\ in head; pectorals If in head ; ventrals short, \\ in pec- 

 toral ; caudal fin truncate, about as long as head; peritoneum black. 

 Color pale olivaceous, covered except on breast with numerous minute 

 dark brown specks, arranged chiefly along the edges of the scales, thus 

 giving the sides and back a checkered or crosshatched appearance ; in 

 addition to these fine punctulations, there are usually 15 to 30 larger spots 

 more or less definitely arranged in two rows lying along or above the axis 

 of the body; in some examples these spots are absent or blended so as to 

 form short, indistinct vertical bars ; in most specimens there is a very 

 obscure lateral band about 1 scale in width ; fins plain or with few very 

 minute punctulations ; top of head dark. Coast of Texas ; not rare in 

 brackish water. (Named for Dr. Oliver Peebles Jenkins, who studied with 

 Dr. Evermann the fishes of the Gulf of California.)

Head 3^ ; depth 4i; eye 3^. D. 10 or 11 ; A. 10 (occasionally 9) ; scales 

 3.5-11, about 22 before the dorsal. Body stout, heavy forward; head

 series, the outer enlarged and canine-like ; jieritoneum pale. Dorsal

 and anterior rim of orbit, or about midway between base of caudal and 

 opercular opening; anal small, its longest rays 1-V in head. Color in 

 alcohol, olivaceous, profusely si)rinkled or dusted all over except on 

 breast with very fine brown punctulations, so abundant on back as to 

 obscure the individual specks ; median line of back with a black stripe from 

 occiput to dorsal fin; sides Avith 10 to 12 or more brown spots of larger 

 size, these sometimes arranged somewhat definitely in two longitudinal 

 lines, in the upper one of which the spots are confluent in some examples, 

 forming large, oblong blotches ; all the fins except the ventrals with 

 numerous very small brown specks. Length 2 inches. Coast of Texas in 

 brackish water ; not rare, (ptilrereus, ■powdery .)
