Depth 41^ ill length measured from snout tip inside rostral exten- 

 sions; head 2%, width IYq. Snout 1% in head; eye 4%, 2^5 in snout, 

 little greater than interorbital ; maxillarj'^ extends % to eye, length 

 2yg in head; mouth width 2; barbel long as head, reaches front of 

 anal, with 10 pairs of filaments ; 2 pairs anteriorly each side of lower 

 mental filaments and 2 filaments on the inner edge of each mandibular 

 ramus or chin, with posterior bifid; mouth edentulous; interorbital 



5 in head; deeply concave, superciliary ridges elevated. Gill rakers 



6 + 19, of which 5 above and 1 below mere low rudiments; slightly 

 longer than gill filaments or 4 in eye. 



Pair of broad, flattened, rounded, rostral extensions, li/^ in eye 

 and interspace equals basal width of either extension; very small, 

 short, median rostral spine at last fourth in snout; small antero- 

 supraorbital spine each side, and pair of postero-supraorbital spines, 

 posterior greatly larger and erect; pair of large erect diverging oc- 

 cipital spines; postocular keel ends in short, small obtuse suprascap- 

 ular spine ; small, slender opercular spine with distinct keel, its length 

 1% in eye; edge of keel of suborbital sta3^ unevenly and slightly 

 undulated, ends behind in long slender preopercular spine reaching 

 1/3 of pectoral, or its length subequal with eye ; rather long asperous 

 keel below and behind hind end of maxillar}^, followed by short one. 



From above gill opening 84+1 bony lateral plates; 4 rows of 

 diminishing spiniferous plates on trunk and tail; spines all large, 

 strong, erect, and surfaces of plates rough rugose ; hind pair of plates 

 on belly before vent 1% in length of front pair; row of 3 small plates, 

 each bearing horizontal keel ending in short spine, above gill opening 

 and 3 similar subvertical or inclined plates behind gill opening.

 ray 5% ; caudal 21/0, little concave behind, truncate as expanded ; least
