either region as distinct. On this point I cannot do better than 

 recall the prefatory remarks of Mr. H. H. Slater in dealing with 

 the Birds, yiz.: " that many of the Himalayan birds, hitherto known 

 only from the Indian side, would on further investigation be 

 found, either in identical forms or as closely-allied representative 



species, in China many of the birds [from Knatun] are of 



genera well known in the Indian hill-country. Now, if N.W. 

 Pohkien were anywhei-e near the Indian boundary the circumstance 

 would be of interest ; far more so when, in the present case, these 

 birds come from a region much nearer to the Pacific coast." This 

 is a confirmation of the view propounded by Mr. H. J. Elwes in his 

 paper " On the Geographical Distribution of Asiatic Birds " \ 

 wherein the Himalo-Burmese and Chinese Avifaunas are shown 

 to be one, and the limits of a '' Himalo-Chinese " subregion are 

 defined. 



EEPTILIA. 



L A C E R T I L I A. 



1. Gecko subpalmatus Gthr. 

 A single female specimen. 



2. ACANTHOSAURA LAMNIDENTATA Blgr. 



Two male specimens. 



The diameter of the orbit being 8 millim. in both specimens, 

 the supracihary spine measures 2, the supratemporal 3 and 2|, 

 the longest nuchal 3 (see measurements in Ann. Mus. Genov. 

 [2] xiii. 1893, p. 317). 



The discovery of this species in China is highly interesting ; it 

 was known only from Pegu, Tenasserim, and the Karin bills. 



3. Ophisaueus haeti, sp. n. (Plate XVI.) 



Lateral teeth conical, curved, pointing backwards, finely striated, 

 with a very feeble groove on the anterior side ; a series of minute 

 teeth on the pterygoids. Azygos prsefrontal narrower than the 

 greatest width of the frontal, in contact with or nai-rowly separated 

 from the latter shield by one pair of pnefrontals ; interparietal 

 broader than the parietals, much broader than the occipital, which 

 is small; two azygos shields between the rostral and the azygos 

 prsefrontal ; five supraoculars. Ear-opening minute, smaller than 

 the nostril. Dorsal scales in 16 longitudinal and 103 to 106 

 transverse series ; 8 or 10 dorsal series obtusely keeled ; lateral 

 and ventral scales smooth, the latter in 10 longitudinal series. 

 No rudiments of limbs externally. Adult pale ohve above, with 

 irregular transverse series of blue spots ; head dotted with blackish; 

 lower parts white. Toung white above, with an interrupted 

 black vertebral line, deep black on the sides and below.
