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

 recall the prefatory remarks of Mr. H. 11. Slater in dealing with 

 the Birds, viz.: " 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 Cliina many of the birds [from Kuatun] are of 



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

 Fohkien were anywhere 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 "' Ilimalo-Chinese " subregion are 

 defined.

1. GrECKO SUBPALMATtrS Gthr. 



A single female specimen. 



2. ACANTUOSAUEA LAMKIDENTATA Blgr. 



Two male specimens. 



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

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

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

 [2] xiii. 1S93, p. 317). 



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

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



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 prtefrontal narrower than the 

 greatest width of the frontal, in contact with or naiTOwly separated 

 from the latter shield by one pair of prtefrontals ; 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 

 tlie 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. Young white above, with an interrupted 

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