 ON A TYPHLOPS NEW TO JAVA 



BY 



Dr. Th. W. VAN LIDTH DE JEUDE. 



June 1901. 



In a collection of reptiles from the Dutch colonies, given 

 to me for identification by Mr. L. Dollo of the Zoological 

 Museum at Brussels, I found two specimens of a Typhlops 

 from Batavia, very much agreeing with Boulenger's descrip- 

 tion of T. polygrammicus Schl., but in some points differ- 

 ing from our typical specimen from Timor. 



The snout is depressed, rounded and strongly projecting, 

 nostrils just visible from below. Rostral about ^/g the width 

 of the head, nearly extending to the level of the eyes, the 

 portion visible from below a little more long than broad, nasal 

 incompletely divided, the cleft extending from the second 

 labial to the surface of the snout; praeocular present, in 

 both specimens as hroad as the nasal, in specimen a broader, 

 in specimen b narrower than the ocular, in contact with 

 the 2"^ and S^d labial. Four upper labials. Diameter of the 

 body 40 to 42 times in the total length. Tail in specimen a 

 1^/3 as long as broad, in specimen b only a little longer 

 than broad, ending in a spine. 22 scales round the body. 

 Specimen a measures 365 mm., specimen b only 340 mm. 



11 rows of dark longitudinal lines on the upper parts, 

 bordered by narrower whitish lines, which latter are formed 

 by the light coloured edges of the scales. Under parts white. 



In our typical specimen of T. polygrammicus the snout 

 is not so much depressed, the nasal cleft proceeds from 

 the Jirst labial, and the lower parts as well as the upper 

 parts show the dark and the whitish lines. 



In our collections are no specimens of T. polygrammicus 

 Schl. from Australia, so that I am unable to compare such 

 specimens with those from Java and Timor, but seeing the 

 differences in the various descriptions, I think that speci- 

 mens from so different localities ought, at least, to be 

 regarded as local varieties of one species.
