FORMOSAN BATEACHIANS AND REPTILES. 221 



9. Elaphe ccü^inata (Günther). 



Two young sjDecimens (No. 10) and one large adult (No. 

 5), the latter from Taipa, form an interesting addition to the 

 fauna of Formosa. The scale formula of one of the young 

 specimens is as follows: — scale rows 23; ventrals 217 ; analYi; 

 caudals ^Ygg ; oculars 2-2 ; temporals 2-3 ; supralabials 8. 



10. Simotes formosanus Günther. 



How little significance the anal shield has in this genus, 

 from which Cope separated Holarchus because of the undivided 

 anal, is shown by the tw^o specimens (No. 17) in the present 

 collection, both from Taipa, one having the anal entire while 

 in the other it is divided. The scale formula is as follows : 

 scale rows 19 ; ventrals 163 ; anal 1 ; caudals ^Ygg ; supralabials 

 8 ; oculars 2-2; temporals 1-2. 



"Rather rare" according to the collector. 



Fam. Natricicïœ. 



11. Natrix stolatus (Linn.). 



Four specimens of this widely distributed species from Taipa 

 (No. 14). The following is the scale formula of one ($): scale 

 rows 19; ventrals 146; anal 7^ ; caudals 'V74 ; supralabials 8, 9; 

 temporals 1-2. 



The collector notes that it is common on the plains around 

 Taipa. 



12. Natrix piscaior (Schneider). 



The known range of this species embraces the whole of 

 southeastern Asia from India to the Malay Peninsula and Archi- 

 pelago, as well as southern China, so that its occurrence in 

 Formosa causes no surprise. The present collection contains 5
