apart is a pair of spines which point upwards, backwards 

 and slightly outwards; running backwards from these are 

 the ridges that bound the wide groove in which the max- 

 illary process fits; these approach each other behind and 

 end in sharp spines which point backwards and upwards ; 

 these spines are midway between middle of eye and 

 the spines behind rostral spines; no median or mova- 

 ble spine at tip of snout; a pair of large -spines above 

 posterior third of eye and a pair of larger ones at occiput, 

 these are continuous with the dorsal ridges ; a curved 

 ridge running from superior orbital rim and ending in a 

 small spine just above opercle ; a small ridge on opercle ; 

 preopercle with a large spine ; a couple of spines below eye 

 at lower edge of suborbitals, running from them to tip of 

 snout is a ridge along lower edge of preorbitals; it is 

 somewhat irregular but without spines ; interorbital space 

 wide and deeply concave, a pair of ridges on each side, 

 converging forwards; supraorbital rim prominent; ante- 

 rior nostril ending in a short, wide, conical papilla, with 

 a small opening at the apex; no noticeable depression at 

 occiput. 



Dorsal ridges converging from the occiput to behind 

 the soft dorsal; they unite on the second plate behind the 

 base of last dorsal ray, this is continued as a single ridge 

 on about 8 plates where it becomes obsolete; the upper 

 lateral ridge follows the course of the lateral line to about 

 the middle of spinous dorsal, where it slants sharply up- 

 ward and is continued to tail above lateral line; lateral 

 line midway between upper and lower lateral ridges pos- 

 teriorly; a single spine above base of pectoral indicating 

 an obsolete ridge between the lateral ridges; lower lateral 

 ridge becoming obsolete under pectoral on 2 or 3 plates 

 behind its base ; abdominal ridges widest apart behind 

 base of ventrals, uniting directly behind anal base and
