386 MR. G. A. BOULENGER ON REPTILES AND [June 5, 



band in most of them is well defined, but in some it is wider than in 

 others. In one of Dr. Staudinger's examples, however, this band is 

 evanescent, and the rich blue of the upper surface of the wings 

 almost reaches to the transverse spots which cross the apex of the 

 wing. There is a black spot within the cell, but this colour does 

 not extend beyond it as in more typical examples. Between this 

 extreme example and the type, the specimens before us may be 

 arranged so as to some extent to bridge the gap between them ; but 

 the series is not so complete as that of A. heatifica described above. 



6. Report on a Collection of Reptiles and Batrachians from 

 the Timor Laut Islands, formed by Mr. H. O. Forbes. 



By Gr. A. BoULENGER, F.Z.S. 



[Eeceived April 30, 1883.] 

 (Plates XLI. & XLII.) 



The Reptiles and Batrachians collected by Mr. Forbes in the 

 Timor Laut Islands, and presented to the British Museum by the 

 British Association, belong to 17 species, which, with the excep- 

 tion of two new to science, were already well known from diiferent 

 parts of the Austro-Malayan Subregion. The two new species are 

 a Lizard of the Australian genus Lophognathus, Gray, and a Snake 

 of the Indian genus Simotes, D. & B. The latter is the most 

 remarkable discovery, as no species of this genus was known to 

 occur eastwards of Java. 



The following is a list of the species collected : —
