Vor. III] VAN DENBURGH—NEW REPTILES AND AMPHIBIANS 53 
ber of the group with seventeen scale-rows. I have examined 
specimens from Kosempo and Kanshirei, Formosa. It gives 
“me much pleasure to name this species in memory of Professor 
Cope, whose studies have thrown so much light upon the 
relationship of the species of natricine snakes. 
Elaphe porphyracea (Cantor) 
Mr. Boulenger has recorded four specimens from Fokien, 
China. It is of much interest to find that the species occurs 
also in Formosa, where it has been taken at Kanshirei, Shin- 
chiku and Giran.
