 Centronotus subfrenatus Gill, Proc. Ac. Nat. Sci. Pliila., 1859, p. 14(r, Hliiinoila. 



Head 8| in length; depth 6|; depth of caudal peduncle ?> in head; 

 e3^e 5f ; snout 5i; interorbital space 10; D. LXXXl; A. II, 89; P, 15. 



Head very small; body elongate, greatly compressed posteriorly; 

 eye rather low in head, the interorbital space greatly arched; lower 

 jaw projectino slightly beyond the upper, maxilliar}^ extending to a 

 vertical through anterior edge of orbit; teeth short, blunt, in narrow 

 bands on both jaws, more numerous on the upper, a few minute teeth 

 on the vomer; gillrakers 2 + l<>, slender, pointed. 



No lateral lines; body covered with minute cycloid scales, which 

 grow outward on membranes of dorsal and anal tins; head completely 

 covered with similar scales except on interorbital space; no tentacles 

 on head; nostrils with small tubes; dorsal with short, rigid, pungent

terior ones 1 in head; anal with 2 strong spines, the longest rays 3^ in

 with the base of caudal, as is also that of the dorsal; caudal rounded, 

 li in head; pectoral narrow, rounded, 2^ in head; ventrals very small, 

 the spines prominent, equal in length to first spine of dorsal. 



Color, variously mottled or l^lotched with l)rownish or blackish on 

 a yellowish-olive background; upper third of body having the color 

 darker than the lower parts; a dark stripe extending downward from 

 eye and upward over interor))ital area; dorsal and anal blotched like

'The following is the substance of Schlegel's account of crn^Hiaphut, a form which 

 we can not separate from nehidoi<us. 



D. LXXVIII; A. II, 40. 



Body greatly compressed, the greatest depth in the region of the anal oitening, 

 contained 8 times in the length; head 9 in length; teeth numerous; scales mimite, 

 delicate, deeply imbedded; dorsal composed of strong spines, somewhat curved, 

 beginning above the pectorals, extending to caudal; the anal begins below the forty- 

 first spine of the dorsal and extends to the caudal; caudal resembling that of E. nehu- 

 losus, except that it is a little larger; pectorals also similar to those of that species. 



Color in spirits, uniform pale reddish brown, darker along tin- base of the dorsal; 

 fins bordered with yellowish. (Schlegel. ) 



This species differs from E. vehulosus, according to Schlegel, in having a smaller 

 head, larger eyes, more strongly curved spines, and a lighter color.
