 attenuate ; dentibus lateralibus magnis, antico approximate-. 



Oblong-elliptic, moderately convex, rather solid, flesh-coloured, 

 with dull crimson rays, the entire surface rough with tooth-like 

 scales, which become more crowded at the rounded anterior extre- 

 mity, and between the distinctly indicated umbonal ridge and the 

 nearly straight posterior edge rise into rather distant elevated tangs ; 

 slopes gentle ; posterior side the longer, its extremity angidated ; 

 ventral edge nearly straight ; teeth very distinct, the lateral large, 

 the anterior lateral approximate, The scales are replaced near the 

 beaks by raised concentric strise. 



An unique specimen, in the cabinet of Mr. Cuming, was found
