In this fish, the muzzle projects a very short, distance in advance of the premaxillary border, and is therefoi-e 

 referred to the same genus as the BhyncMtUhyt braehyrhynchus of Bleeker, as proposed by Gtll, though without 



entire confidence, as I have not, seen the latter species. 



The premaxillary groove open in Myrioprittis, is here over-roofed and closed by the extension of the bones of 

 the front, ; the spines of the premaxillaries are very short. On the vertex is a short, supraoccipital corona. In front 

 of and on eaeli side of this, two approximated crests rise, which extend to the end of the muzzle. They enclose a 



groove which is narrower 

 and deeper on the anterior 

 half the cranium. Exter- 

 nal to these, a low ridge 

 extends from each pterotic 

 region, parallel to the 

 other. Above the posterior 

 border of the pupil they 



diverge to the front margin 

 of the orbit, ami then eon- 

 verge to the end of the 

 muzzle. A bony thicken- 

 ing on each side marks the 

 union of these ridges with 

 the median. From this a 

 strong ridge extends along 

 the posterior margin of the 

 preorbital bone, enclosing 



in the angle with the lateral, the nares. Its edge is serrate, as is also that of another high crest, on its front edge. 

 Post frontal region, ridged ; four teeth on posterior rim of orbit. Prcoporeulum, serrate coarsely behind and below, 

 with rudimental spine at angle. Int.eroperculum, suboperculum, and operculum serrate, the hitter with one sub- 

 median spine. Clavicle, epiolaviclc and " posttcmporal" toothed. Eye 2T, times, interorbital width 8 times, in length 

 of bead. Last 8-2 times in length to basis of caudal ; depth in same 2-75 times. Scales ',', -88 -7. Pin rays D. X I .
