Nine specimens (U.S.N.M. Nos. 34170-78) from Taipe, Formosa, ap- 

 pear to be typical T. septentrionalis with one inguinal pore on each 

 side and three submandibular shields. They have a moderately 

 broad head and moderately large temporals, about seven in a row 

 between orbit and ear-opening, and in these points as well as in 

 coloration difl'er from T. smaragdiiius which normally also has two 

 more rows of large dorsals. I have compared them with two Chinese 

 specimens collected by Dr. Eliot Blackwelder, in the Chin Ling ^h)im- 

 tains in the Province of Shansi (U.vS.N.M.Nos. 85525-26). 



The relations to T. formosanus will be discussed under the latter.
