Show 160 MR. G. A. BOULENGER ON REPTILES [Feb. 21, 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, 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 China many of the birds [from Kuatun] are of genera well known in the Indian hill-country. Now, if N.W. Fohkien Avere anyAvhere 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 vieAv propounded by Mr. H . J. Elwes in his paper " O n 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. REPTILIA. LACERTILIA. 1. GECKO SUBPALMATUS Gthr. A single female specimen. 2. ACANTHOSATJRA LAMNIDENTATA Blgr. Two male specimens. The diameter of the orbit being 8 millim. 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. 1893, p. 317). The discovery of this species in China is highly interesting ; it Avas known only from Pegu, Tenasserim, and the Karin hills. 3. OPHISAURUS HARTI, sp. n. (Plate XVI.) Lateral teeth conical, curved, pointing backAvards, finely striated, with a very feeble groove on the anterior side; a series of minute teeth on the pterygoids. Azygos praefrontal narroAver than the greatest Avidth of the frontal, in contact with or narroAvly separated from the latter shield by one pair of prefrontals; interparietal broader than the parietals, much broader than the occipital, which is small; two azygos shields between the rostral and the azygos prefrontal; 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. N o rudiments of limbs externally. Adult pale olive above, with irregular transverse series of blue spots ; head dotted Avith blackish; lower parts white. Young white above, with an interrupted black vertebral line, deep black on the sides and below. 1 P. Z. S. 1873 p. 615. |
