Remark. — The lateral shields of head are subject to various modi- 

 fications, viz., the fourth supralabial may enter the eye when subocular 

 is not present ; the number of supralabials is variable. Chin-shields 

 in specimen No. 65 of the Formosan Museum and in specimen No. 

 35 of the Medical School are differentiated, while in the two other 

 specimens, there are recognizable two pairs of enlarged scales not in 

 contact with each other. 



Family Cobridse.
