FOBMOSAN BATRACHIANS AND REPTILES. 225 



Fam. Cvotalidœ. 



18. Trimeresu7'us m.uci'osquamatus (Cantor?). 



Three specimens from Taipa, two adult (No. 6) and one 

 young (No. 18), agree with Boulenger's description of other 

 Formosan specimens. 



19. Trimeresurus gramineus (Shaw). 



Of this widely distributed species there are four specimens 

 (No. 2) from Taihoku (Taipa). I have compared them with 

 specimens in the U. S. National Museum from Lower Siam, and 

 can see no essential différence. 



The collector remarks that this species is often found in 

 the woods climbing on the trees, being difficult to see on account 

 of its green color. It is common, especially in northern Formosa. 

 The native name means "Green Bamboo Thread." 



Old. Testudinata. 



Fam. Btnydidce. 



20. Ocadia sinensis Gray. 



A young specimen from Taipa (No. 29), September, 1896, 

 sliows all the characters assigned to this species except that the 

 edges of both jaws are smooth, not finely denticulated. The 

 suture between the humerais appears to be abnormally long at 

 tlie expense of that of the pectorals which is not as long as 

 that of the pectorals and gulars together. Crown of the head 

 uniform olive brown, rest of head wdth the characteiistic narrow 

 longitudinal yellowish lines. 



The collector says that it is common in Tamsui River.
