Remark. 



— The s 



secimen 



No. 20 



in the 



Bureau 



Sci 



. Res. 



and 



the 



specimen No. 40 in the Formosan Museum have a small sub-prcocular. 

 The latter specimen shows a great variation in the number of 

 temporals, the second row of these being non-existent owing to 

 confluence. The upper shield of second row is coalescent with parietal, 

 forming a quadrangular shield.
