./. I I'ANESE SrVL PINS— JORDAN AND STARRS. 295 



pr(M)p(M-('l(' with ?) sharp subequal spines, the upper one directed 

 downward and backward, the middle one downward, and the lower 

 one hooked forward. Niisal spines well developed. On top of head 

 from cA'e running' Ijackward is a low, rounded ridge, which is scarcely 

 broken, though shows slight indications of tubercles. 



Over posterior margin of eye is a prominent ])lunt tubei-cle which 

 does not bear a tentacle. Top of head thickly covered with rough 

 bony plates which extend forward on interorbital space to front of 

 ej'e. Similar plates on opercle. toj) of })i'(H)percle and on cheek behind 

 eye. Humeral spin<^ vej-y shoi't and ])lunt. not nearly so long as in 

 G. intcTin cdiiis. 



Lateral line with concealed bony plates. A few I'ough scattered 

 plates behind pectoral base much more numerous and regular in the 

 male than in the female; no axial tentacles. 



Middle dorsal spines the longest; spinous dorsal rather high in 

 front, the spines growing rapidly shorter behind the middle in the 

 female, holding their length nearly to the last in the male. Dorsals 

 well separated. Soft dorsal highest anteriorly, the rays growing 

 gradually shorter posteriorly; the last ray not adnate; tips of the last 

 rays not reaching so far posteriori}^ as do those of anal, which do not 

 reach to within a diameter of the eye of the base of the caudal. Pec- 

 torals with 19 rays, its posterior outline broadly rounded, r(>aching to 

 above base of second anal ray in the female, to above fourth anal ray 

 in the male. Middle ventral ray the longest, not reaching vent in 

 female, reaching past vent nearly to anal in male. Caudal rather 

 deeply concave, even when tin is spread; the outer rays half the 

 diameter of the eye longer than the middle ones. 



Color nearly luiiform light slaty brown above, in spirits, without 

 spots or crossbars, changing abruptly to silvery white just below 

 middle of sides; a diHused dusky blotch on cheek; membrane behind 

 maxillary dark slate-color; bi-anchiostegals dusky in male; silvery 

 white in female; spinous dors;d with 8 black or dark brown bands 

 following the upper outline of the tin, the upper one bordering the 

 upper edge; posteriorly the bands are ))roken; in the female they are 

 narrow and diffused, and in the male they are broad, conspicuous, and 

 wider than the white inters})ac(\s; similar l)ands on soft dorsal showing 

 the same modifications in both sexes, but running obliijuely downward 

 and backward; 2 dark cross bands on caudal: 8 and the beginning of 

 a foui'th vertical dark cross bands on ])ectoral, wider on male: anal 

 and ventrals white in female: the former with an indistinct dusky 

 longitudinal band in male.
