Order OPHIDIA. 

 Fam. Typhlopidje. 



1. Typhlops bkaminus Daud. 



2. Typhlops nigeoalbus Dum. et Bibr.^ 



Typhlops nigroalhus, Boulenger, Cat. Saakes, i. p. 24 ; S. S. 

 Flower, P. Z. S. 1899, p. 653. 



Several specimens, agreeing closely with the example described 

 by Boulenger in the ' Catalogue,' from Jalor and Kuala Aring. In 

 none of these, however, does the rostral shield extend to the level 

 of the eye. In this respect it agrees with T. muelleri Schleg. 

 from Sumatra, but differs from this latter in having the breadth ot" 

 the rostral shield as in T. nigroalhus. Our specimens seem, then, 

 to be intermediate between these two species. Largest specimen 

 424 mm. in total length. 



Fam. BoiDj3. 



3. Python reticulatus (Schneid.). 



Fam. Ilysiid^. 



4. Cylindrophts riteus (Laur.).

One specimen from Biserat, lacking the vermilion colour on the 

 tail. Called " Ular gelenggaug " (sugar-mill snake).

^ For explanation of the Plate, see p. 583. 



^ Since this paper was read I find that Werner (Zool. Jahrb. Syst. xiii. p. 488) 

 is of opinion that T. nigroalhus D. et B.= 2'. muelleri Schleg.
