 ossified. The crown of the head is slightly convex, smooth, with a 

 feeble occipital crest posteriori)' ; interorbital space ^vith a longitu- 

 dinal groove and with a pair of v,nde pores anteriorly ; turbinal bones 

 concave, spoon-like. Maxillary elongate, triangular, much dilated 

 posteriorly ; intermaxillary with short posterior processes. The in- 

 fraorbital ring is throvighout of nearly equal Avidth, rather narrow 

 and firm. Bottom of the tympanic groove osseous. The limbs of 

 the praeoperculum are provided -wdth a very distinct muciferous 

 channel, and of nearly ecjual length ; they meet at an obtuse angle. 

 Operculum with an internal longitudinal ridge terminatin"g in a short 

 spine. The cavity for the pectoral mxiscles is rather small. Fifteen 

 abdominal and fifty-four caudal vertebra? ; vertebra? compressed ;
