Length of head 4|, height of body 4| in the total length. Eyes 

 diameter 4| in length of head, | diam. from end of snout, and 

 1 apart. The maxilla reaches half a diameter behind the orbit. 

 Vertical margin of preopercle strongly denticulated, with a rather 

 strong tooth above its rounded, produced, but entire angle. Teeth 

 villiform in jaws, in a semilunar band on the vomer, and in an 

 interrupted one on the palatines. Fins third dorsal spine highest ; 

 second dorsal one fourth higher anteriorly than the anal, its upper 

 edge rather concave. The pectoral rays unbranched, the free ones 

 reach to rather beyond the end of the ventral ; base of anal slightly 

 longer than that of second dorsal ; caudal deeply forked. A spine 

 on the shoulder at the commencement of the lateral line. Ccecal 

 appendages long and rather numerous. Air-bladder large. 

 Colour golden ; pectoral deep black ; a lower black edge to the

Length of head 4| to 4, height of body 6 in the total length 

 (excluding the filamentous prolongation of the tail). Eyes 

 diameter 7 in length of head, 1 to 1 ^ diam. from end of snout, and 

 2 apart. The maxilla reaches to far behind the orbit. Preopercle 

 \vith a rounded and produced angle, its posterior margin mode- 

 rately serrated, and having a strong tooth above its angle. Inter- 

 orbital space rather flat. Teeth in a somewhat semiluuar band on 

 the vomer, and in a wide cuneiform baud, broadest anteriorly, on 

 the palatines, the last emarginate internally about its middle. 

 Fins spines of first dorsal weak, the third having a rather fila- 

 mentous prolongation, the fin one third higher than long ; second 

 dorsal highest in front, where it equals the anal and is one third 

 higher than its base is long ; upper edge of the fin concave. Pec- 

 toral with its rays branched, having five articulated free rays, the 

 upper of which is the longest, reaching nearly to the anal ; the 

 latter fin extends posteriorly some distance behind the vertical 

 from the end of the second dorsal, and is concave below. Caudal 

 deeply lunate, with pointed lobes, which usually have filamentous 

 terminations, the lower mostly the longer. Air-bladder oval and 

 thick, occupying the entire length of the abdomen, and posteriorly
