 guous. Nostril in the middle of an oblong scale, often divided 

 by a suture above and below the nostril, as if in the middle be- 

 tween two scales. Frontoparietal 2, contiguous. Palate vvith a 

 central slit, widened at its front end and toothed behind. Low-

 plates soldered togetb.er, with the nostril in the suture. Some- 

 limes the front portion is much the largest, triangular, as in P. 

 auratus, and may be mistaken for a second supranasal plate.
