REPTILES FROM NIAS. 255 



back and 2 on each flauk. These lines are formed by 

 small elongate dark spots on the scales , such a spot flow- 

 ing together with that on the preceding and the follow- 

 ing scale. These lines are situated on the '6^^, the 5^^, 

 the 7*^, the 9^^ and the 11th longitudinal series of scales. 

 The abdominal-shields are whitish , with several very small 

 irregular dark spots anastomosing with each other , and 

 so forming a dark cross-band at the anterior part of each 

 abdominal-shield. This band is broadest in the middle of 

 the shield. Underneath the tail the colour is whitish with a 

 dark subcaudal line. The coloration of this species shows some 

 resemblance with C. gervaisi D. & B. differing from it in 

 presenting 5 in stead of 4 longitudinal dark lines. 



Our specimen, captured in the isle of Java, has 190 

 abdominal- and 22 pairs of subcaudal-shields. 



*6. Cydophis tricolor Schl. 



This interesting snake is represented in Mr. Pasteur's 

 collection by a single specimen. Hitherto it is, as far as 

 I know of, recorded from Java by Schlegel (and afterwards 

 by Giinther and Jan, though probably after specimens 

 from the Leyden Museum), and from Sumatra by Stoliczka ^). 

 In the collections of the Leyden Museum there is one 

 specimen from Sumatra, and another from Borneo. 



7. Simotes purpurascens Schl. 



The single specimen by which this snake is represented 

 in Mr. Pasteur's collection agrees in all points with the 

 description given by Fischer of Simotes ajjinis "). It has 8 

 upper- and 9 lower-labials on each side, and differs in 

 this point from the specimen mentioned in Boulenger's 

 list under the name of S. labuanensis Gthr. which is said 

 to have 7 upper- and 8 lower-labials ^).
