410 NEW FISHES FROM PACIFIC OCEAN— GILBERT 4- CRAMER. vol.xix. 



equal; least depth of ])e(luTJcle 2^- in greatest deptli of trniilc. Head 

 heavy, compressed, it jireatest Avidtli U;, and its width in front of orbit 

 3 in its o-reatest deptli. Snout very blunt and short, its interior pro 

 tik^ nearly vertical. Orbit moderate, far forward, nearly circular, 3 to 

 3.^ in head. Interorbital space broad, convex, its width equal to orI)it. 

 A sliglit median ridjj,e running up onto the interorbital si)ace. Sleuth 

 large, obli»iue, the maxillary slender, 1| in head, its posterior end 

 extending about one third of its total length beyond the posterior rim 

 of orbit. Teeth small, in narrow bands on Jaws and i)ahitines; a single 

 scries on each jaw larger than the rest. A large patch of suuvll teeth or 

 asperities on pterygoid. Posterior edge of i)reopercle directed upward 

 and forward. Opende with a long, triangular i)ointed lobe, about on 

 a le'. "1 with lower edge of orbit and extending beyond the root of the 

 pectoral, the edges above and below the lobe slightly emarginate. 

 barely covering the gills. Gill rakers slender. 2 in orbit, 15 on hori- 

 zontal limb of first arch. Bones of head thin and flexible. Xo distinct 

 orbital or postorbital si)ine. 



Scales thin, cycloid, not serrated, moderate, those of lateral line not 

 enlarged; 3 in a transverse scries between lateral line and origin of 

 dorsal. Cheeks, oi)ercles, and interoi'bital space scaly. 



Photophorcs. — Mandibulars 3 pairs, operculars 2, the upper appar- 

 ently double, the lower minute, behind angle of jaw; ])ectorals 3, the 

 uppermost above opercular lobe at lower edge of second or third scale 

 of lateral line, the second in front of middle of base of fin, and the 

 third midway between this and the foremost thoracic spot, the three 

 forming an obtuse angle at base of ])ectoral fin. Thoracic •">, the first 

 and second pairs far apart, the fourth ])air almost directlj" outside of 

 the third. Supraventral 1, about midway between lateral line and 

 and base of ventral fin : ventrals 5, the first pair close together between 

 bases of ventral fins; the first three efpiidistant and forming a straight 

 line diverging backward from midventral line; supraanals 4, one imme- 

 diately und<'r lateral line and forming with two others a straight line 

 extending oblicpiely downward and forward, the fourth a little above 

 and in front of the first anterior anal spot; anterior anals 5, equidis- 

 tant, the last three forming a gentle curve upward toward the ])ostero- 

 lateral; posterolateral 1, under lateral line and a very little behind 

 the hindermost anteiior anal; posterior aiuils 5, equidistant; caudals 

 4, ecjuidistaut, in a gentle curve with the concavity forward. The spots 

 are divided by a black se])tum. Anteorbital gland, orange-colored: a 

 triangular or heart-shaped portion of it at the antero-<lorsal angle of 

 orbit; within and belowthis the organ occupies the entire area between 

 orbit and middle line down to nostrils and between orbit and maxillary 

 backward to about the \('rtical from the center of the eye. 



Distance from tip of snout to origin of first dorsal and to base of ven- 

 trals 2| in length of body, from tip of snout to origin of anal 1|, base 

 of dorsal 4i to 5, base of anal <t, from root of i^cctorals to root of ven- 

 trals 0.| in length of body. Pectorals inserted low, below the line
